Any blue campanula or other blue perennials? I'm going to try some larkspur (annual) hoping it will reseed too.

annual larkspur is purple

Have you tried Delphinium Summer Nights? It's supposed to be longer-lived than the regular Delphiniums. I had Del. Butterfly Blue last year but it didn't overwinter for me.

I'm growing some annual Lupin Sunrise that look true blue and yellow. Didn't get around to planting Lupin Nanus Blue Bonnet, another annual.

I had just one larkspur come up in a bad place, think it was true dark blue.

I've got seeds for a petunia "Blue Daddy". It had better be true blue. I thought I had one in a mix but it was purple. Again.

Lobelia, true light blue maybe a dark blue.

Iris, Mariposa Skies also we shall see what Princess Caroline is.

Seeds for nemophilia mensiessii Baby Blue Eyes

I have seedlings almost ready to transplant of Bluebird Delphinium, looks darkish true blue w/white eyes, we shall see. Why won't they do well for you? Some are going into a hot spot w/soaker hose and for safety will put the others someplace else.

Viola sorbet Yesterday Today and Tomorrow, squirrels dug in the planter box but looks different shades of true blue and white, will try again. Bet it's purplish.

Adenophors Bulleyana looks true blue on the packet, I haven't succeeded in growing them from seed, but all the photos I've seen look purple.

There are some Siberian iris I ordered and one I didn't but like that look true blue. We shall see.

I have seen a true blue columbine but never been fortunate enough to find one in a garden center, always out B4 I get there or don't have them.

Salvia Blue Crystal looked true blue in Burpee's photo but was not; it was you guessed it.

Blue Dreams Catmint is not blue, you guessed that, too. My meadow sage is purple.

I'm looking for a true blue clematis. C. Rooguchi which I have comes very very close to dark blue but has a hint of purple in it.

Bluebells (the Virginia kind) I couldn't get to grow yet, they look true blue.

Also I think Texas Blue Bonnet is true blue and may possibly be grown as an annual in some more northern zones.

There is a true blue poppy, mencosis or something, but not for my zone.

Some varieties of hydrangea will bloom true blue in alkaline soil, pink in acidic.

What did I leave out? True blue of any shade is one of my theme colors to coordinate with or complement my house which is now painted true blue. I've always been crazy about blue flowers anyway.

Roses are red and violets are blue, haven't seen a true blue wild violet yet.

Oh, scilla and hyacinths are true blue. Also if you can find lycoris squagimera which should grow well in your zone, it's gorgeous, pinkish, purple, lavender, yellow throats and tipped in true sky blue, have a photo of that. I planted 5 and they came up but never bloomed in the early fall like they are supposed to. Now I lost a couple over the winter but 3 are up and one multiplied. I'm still waiting.

salvia ulignosa (bog sage) is a pale blue with pure white, bi-color:

There are some blue irises, starting with Dutch irises, then bearded irises.

* Plumbago (electric blue)

* Brunnera (sky blue)

Flax immediately comes to mind as well as the before mentioned plumbago.

~Chills

I could use some Rozanne geraniums, read a discussion about them, but would want to be sure of the color. I think I'm done for this year though.

Spiderwort, came up as a volunteer from somewhere in back in a spot that's not too good, love it, but it never came back.

Annette

I think an all blue garden might be pretty; mine I'd like to interplant with some white. Some of the blues w/other colors sprinkled in them would accentuate it all.

I'm pretty sure Blue Daddy petunia is not going to be blue, remember I did plant some last year. They are purple but really pretty anyway. I'll look for the petunia the other poster mentioned.

Brunneras are true blue as are forget me nots. I've got an aquatic forget me not in the pond that blooms for months and doesn't mildew like the early spring one does in the garden.

My 'Rozanne' hardy geraniums are not true blue, they are fabulous but they are lavender.

'Heavenly Blue' morning glories are sky blue and gorgeous but I've had trouble with the seed packages not containing the right ones.

Caryopteris are not bright cobalt blue but they are very close to blue, more close than the 'Rozanne' geranium for me. Ditto Perovskia

There are three plumbagos, one is tropical and sky blue (Plumbago auriculata) and the other two are hardy and electric cobalt blue, one ground cover, one subshrub (Ceratostigma).

I've killed Lithodora over and over but it is electric blue.

Muscari, Grape Hyacinth is true blue but invasive. True Hyacinths also come in blue. There are blue Scilla/Squill bulbs as well but some are also invasive.

There are true blue Iris both bulbs and bearded, I love the dwarf reticulatas early in spring. I've got light blue and bright blue.

Delphinium bella donna come in electric cobalt blue but they are difficult to get to behave as perennials same as regular Delphiniums which don't have quite the same electric blue color. I've never seen a true blue Larkspur they are all purplish, not that that is a bad thing. I was a florist for twenty years and D. bella donna was the primary cobalt flower I used for weddings since it was available year 'round and always true blue.

I've killed at least six blue Corydalis

Plumonaria are true blue perennials but sometimes combined with pink.

Annette

I love my Cranesbill 'Rozanne' but mine is nothing approaching blue. I would call it a medium purple.

I am trying Salvia 'blue hill' this year, not sure how blue it will end up.

Thank you, buyorsell for the seed offer! In the past I have not done so well with seeds. Maybe I'll look for blue columbine next spring.

For some reason, brunnera and forget-me-not does not like my soil, I can't remember if it is the clay or the alkaline nature.

Some of the other options: plumbago, blue poppy (does this like humid conditions?), cerastostigma and caryopteris.....where do you buy those? Locally or online? Thanks everyone!

I just went outside and looked at it again and it isn't true blue but is bluish lavender/periwinkle in color. I remembered it being true blue but I was wrong. There was a forget me not right there for comparison.

I am just commenting on plants I myself have grown and found to be a 'true blue'. Not sure if you are looking for a deep, medium, or light blue?? I am sure several of these have been mentioned, but I will just throw them out there again.

Ajuga- Bugle Weed. Several interesting cultivars. The variegated kinds do not spread as fast for me. Deep or med blue.

Anchusa- Bugloss. I bought one last year. Wonderful deep blue flowers. I thought I killed mine, but it is up.

Aquilegia- Columbine. Lots of blue kinds/cultivars available. Make sure you buy one in bloom. I have often bought one only to find out later that it wasn't the right one.

Aster frikartii 'Monch' is a light blue. I would compare it to perriwinkle. I also have one, A. tongolensis 'Wartburg Star' that is a bright med blue. Great little Aster.

Brunnera of course. Sky Blue color, brighter than forget-me-nots.

Campanula- many kinds are blue. My C. 'Blue Uniform' (Uniform Blue) is a medium blue. Great mounding little plant.

Centaurea montana- Perennial Bachelor Buttons. They are indeed a deep blue. They can look a little 'purple' from far away, but up close you will see the petals are blue.

Corydalis elata- the blue Corydalis. Mine is just going to bloom. It bloomed last year, but this is my first full year with it. It is doing okay, though the foliage is getting a tad yellow.

Echinops- Globe Thistle. I grow 'Blue Glow' and it is a true-blue.

Erigeron speciosus 'Azure Fairy'- Fleabane. LOVE THIS PLANT! It looks a lot like an Aster, but it much easier to grow. It has incredibly bright med blue flowers. Beauty!

Eryngium- Sea Holly. I only grow 'Jade Frost' (with variegated foliage), but I know most other Sea Holly are blue. Mine has really nice blue color that fades to silvery-blue.

Geranium (perennial). G. magnificum is amazing. Medium deep blue flowers. Simply amazing color; you could just dive into it!

Hyssopus officinalis- my 'Dwarf Blue' is the deepest blue you will ever find. I adore this plant. It stays small and tidy. Foliage stinks, flowers don't last very long, but that doesn't bother me. Great edging plant. It is one of my favs. Also an herb.

Scabiosa- I have several unknown kinds. One looks like 'Butterfly Blue' and the other similar to 'Deep Waters'. Both are a light blue.

Linum- Blue Flax. Good medium blue color with blueish colored foliage to boot. Great for a filler plant.

Nepeta- Catmint. My N. subsessilis has beautiful true-blue flowers. Med deep blue. What a hardy plant.

Lupine. I have a cultivar called 'The Governor', which has deep blue flowers with some white.

Platycondon- Balloon Flower. I have one that I belive is 'Sensation Blue' or something like that. You will never find a bluer blue than this!

Polemonium- Jacobs Ladder. My 'Blue Wirl' is a deep blue. 'Brise d' Anjou' has grown well for me too.

Veronica 'Crater Lake Blue' has deeeep blue flowers. Doesn't bloom long. I am having foliage problems with it. 'Royal Candles' has deep blue flowers too. Great plant. Never fails me.

I also want to mention that the shrub Caryopteris (bluebeard) had dark blue flowers. And the bulb scilla, which has small dark blue flowers. Don't forget Pansy. ;-)

You can't tell I like blue flowers, can you?
CMK

Dracocephalum- Dragon's Head. I have 'Fuji Blue'. It is just budding now; this is my first full year with it.

Rosemary has blue flowers. Annual for me, might be perennial for you in a protected site.

Anemone nemorosa 'Robinsoniana'- Wind Anemone. Such a welcome sight in early spring! Medium blue flowers.

Campanula persicifolia 'La Belle' has double med blue flowers. Doesn't reseed.

Omphalodes- Blue Eyed Mary. Semi-shade plant with dark blue flowers. Flowers resemble Forget me nots but are larger. I have O. cappadocia 'Starry Eyes', which have blue flowers with a white edge around the petals. O. verna have fully blue flowers.
CMK

My 'Princess Caroline' Iris is the bluest light blue in the whole world - it's breathtaking. I wish it would bloom all summer.

Westy

Love that morning glory. Never did get one here, they were all various shades of purple even though seeds and pots labeled 'Heavenly Blue'

I have purchased my caryopteris and pretty much everything else locally. I don't mail order many plants.

Also, I agree with what everyone else has suggested above.

Karen

I can definitely relate to what you are saying about the blues actually being purples and mauves. The photos of Karen's Salvia are an example... To me that's purple and not a true blue.

I do grow the Meconopsis Benotifolia in my gardens (from seed), and they are the truest blue I have seen in gardens. Unfortunately, I don't think your weather would make them happy. We have coolish summers which they like. Here's a photo...

A close-up of the flowers...

I do have other blues in the gardens which come really close and are true blues as well. Anchusa - Common Bugloss, Cynoglossum - Annual Forget-Me-Not, and the Nikko Blue Hydrangea (we have extremely acidic soil...).

I also grow this viola, but it's not a big plant. Can't remember the name.

Here's Brunnera Jack Frost in my gardens. It reseeded itself and there's lots of little ones this year. :O)

Centaurea montana is indeed a reliable, true blue plant (heh) but the foliage looks awful in between bloom cycles. I have it planted with Phlox paniculata 'Laura' which blooms in the exact same vibrant magenta-purple as the center of the bachelor buttons.

I just planted a brunnera Jack Frost, hope it self seeds, didn't know if it would multiply or not.

kristin, that is an especially stunning Heavenly Blue. It's got darker spokes in the flowers, not typical of the ones I've seen. I've never started any from seed, but a bird dropped a smaller blue one, it comes back every year, and I can't get rid of it. Maybe I'm finally rid of it but bet more seeds will sprout next year. It gets tangled in my forsythia bush nearby which I don't want.

One year I had it tumbling over a milk can, then allowed some to climb on my porch rails, went crazy. The only thing is that in really hot spots in the heat of the summer, they will wilt, and I have to quickly water them. Most people don't seem to bother with them, and they come back every year by self seeding once established. They do like sun, but that one looks like it might be part shade.

Thanks tiffy for the great pics! :)

It came to me l;ast night - Ultima Morpho Pansy is what it actually is. The flower is small like a viola. Mine were seed and they came out with a lot more blue/less white than they are suppose to.

My earliest "themed" section of the garden was a "blue" garden, and I'm still
tinkering with it 15 years later. . . ALL blue that first year was just redundant
and kind of boring . . . in subsequent years, mixing in a few whites made a
huge difference in way the bed would "read" - but the real revelation came
the year that I was wandering about the garden with a birthday gift, and just
happened to set it down in front of my blue bed. WOW !!! The gift, in bloom, was a soft yellow hemerocallis ('So Lovely') . . . and it was the YELLOW that finally made my blue garden sing! You can overdo it, of course, but through all the seasons now, I try to have a bit of yellow (preferably a soft yellow) tucked in somewhere amongst the blues.

By the way, someone above dismissed the tender perennial salvias because
they weren't hardy in their zone: a Salvia guaranitica is featured every year
in the blue garden here (Z. 6b) - I just treat it as an annual. . .surely, a 5-foot explosion of purest blue (in one season!) is worth a couple of dollars each season. . .

I was SO hoping you'd remember. Now to find some seeds. I see things I can live without, but those are so enchanting I want some so bad. Yes, I have other viola seeds to plant, but they pale in comparison to that, so what if they peter out in the heat (read you should cut them back by 1/2 in early June - maybe a little later in our zone)?

Do you remember where you bought the seed or which brand? I'll google, but one vendor's seeds may not be the same as another's. I was even thinking about asking you to send me some seeds, that should be ok from Canada, but not plants. Best I buy my own if I can find some, like 5 packets. But I don't have a clue how to save viola seeds, probably don't have anything you'd want in trade, problem crossing border anyway, I'd be willing to BUY seeds from you if there's no other way.

Googling now. Vesey's shows theirs as nice blue and yellow combo. Pretty but no. Big Dipper Farm, blue and yellow again, but more blue. Nature Hills. Purple and blue. No. They have another one called "Got the Blues", it has more of a face, but could settle as a substitute.

That's enough, more pages to sift through. Now I'm wondering if yours is a mutation, a very special one. Yours has just the tinest yellow eye but all else blue with the pretty, darker blue lines.

Back to earth. I just remembered my alliums, put tons in for accents. Mine is true blue, think I got those from Bluestone. Photo didn't lie for once but who knows what their next batch might be? The head isn't as big as some, could be my soil; my granddaughter is here visiting and just loves it. Mine aren't multiplying like they say they do. They last quite awhile but don't bloom all summer.

Also while I was putzing on the web, I found Blue Monkey Flower, mimulus, looked blue but think it's not for my zone and don't remember ever seeing any even in a public conservatory.

Pls forgive if already mentioned; we've got quite a compendium here now, never imagined there were so many true blue flowers. And the really crazy thing is if they come up with a true blue rose, I don't want it, love roses, but wouldn't seem natural to me.

Vesey's is where I got the seeds from. I buy seeds from there most years. I can most certainly try to get seeds. Got to catch them just at the right time, so I'll see if I can get you a few.

Redsox,
The rabbits are in the neighbourhood but have yet to step on our property. It's just a matter of time... SIGHHHHH. I think they sense my Black Lab.

Vesey's is where I got the seeds from. I buy seeds from there most years. I can most certainly try to get seeds

Prepare for one of my longish ones - :-) or :-(, take your pick. I figured you got them from there because I saw a photo, saw you were somewhere in like Nova Scotia, and some were blue and yellow whereas others were all blue (morphed back?) (customer photo). So maybe you just got lucky.

So I found Veseys in the US, hardly anything to choose from, none of those whatsoever, so went to the Canadian site, put some in my cart along with a couple other things, went to checkout. It wanted a catalog? code also Canadian zip code. Now I'm seriously worried.

so I'll see if I can get you a few.

That is soooooo sweet of you. But NO NO NO and here's why.

I found the Canadian 800# and called, was told there was no way they could or would ship to the US. Something about the border inspection (I have bought lots of roses from Pickering but they do have some kind of pre-arrangement with the border people). So I asked what if a friend (not thinking I'd ask you but somehow some way) went there, bought them and returned with them. The lady said that I/they would be taking their chances and would risk having them confiscated, not sure they would, not sure they wouldn't. They do have Americans come through to buy things, maybe have an actual store and not just a website. She didn't want to tell me the exact location though, thought that was odd, oh well. I told her I did not want to do anything illegal.

So my heart kind of sank, and I started looking in the US. One place only sells live plants, too late for that anyway. Then I googled and started going down the list. Some were just info-type sites, some no photo, some wrong color, checked davesgarden.com. One vendor. Checked that, can't remember why that wasn't a good option.

I finally found some at Swallowtail seeds, same price as Veseys (kind of expensive), and no reduced price for buying at reduced price by the 100's.

So I major splurged and ordered 6 packets of that and two other things. I needed some insurance to try germinating different ways; usually I don't order that many even if I want a lot. They will probably self sow for me if I get them going in some spots conducive to it, plus they are listed under perennials and not annuals.

If I get lucky and get some plants, I'll be happy enough if they are blue and yellow, and maybe some will revert or whatever yours did, think it's a good chance for that. The photo was just like the one I saw at Veseys I think.

Then if I get some blue ones like yours, I'll try to find out how to save the seeds, and either keep the others or try to plant them in separated areas of the yard for accents, borders and planters, I know that won't guarantee color because of being hybridized but ups my chances.

So all is well for now. I have you to thank for introducing me to that beautiful flower!!!

To the poster about growing salvias as annuals, that is an option. It's not top priority right now, but I'll see how my blues go, how much space I fill w/this year's seeds (not doing that great) and keep that one in mind; money for seeds is a small price compared to some roses and stuff for the yard and garden I've bought.

Salvia Patens is a lighter blue version of the Black & Blue listed above. Mysotis has a range of blues. Now that I take a really good look at my garden, I realize I NEED more blues. Thanks for this thread!

Nancy VB

Salvia 'Mystic Spires' is a very dark blue, almost navy blue. I'm still working on the best companion colors -- gaillardia 'Golden Goblin' is what I've placed beside it, but that's not yet in full bloom. Zinnias in pinks, green or orange look good, too.

Also, an annual north of Zone 8b but perennial in its native habitat, Evolvulus glomeratus 'Blue Daze' is true blue.

Uploaded with ImageShack.us

Have never seen a blue Campanula, and I had really many. Amsonias are pastel blue. None of Anemone nemorosa clones is true blue(I had them all).
