Thanks for your kind words, Lin.
I actually prefer this white variant over the regular "blue" ones. Any idea if the white flowered type will come true from seed? The plant in question is isolated from the others.

that depends on their pollination habit/technique, I once had volunteers of a white Centranthus ruber, all of them white as well; clueless about Dianthus though, self-pollination would make that happen,

bye, Lin.

Looks like Patty meant to say Coreopsis Galaxy, not Mercury Rising. Love the combo of those together, though. Beautiful!

What you are discovering online is correct - other than these both being a variegated cultivar of euphorbia, they are nothing alike. 'Silver Swan' is a sliver-white variegated selection of E. characias. It blooms with a pale, greeny-white flower bract and should get to about 30-36" tall.

'Ascot Rainbow' is a variegated xmartinii hybrid. It has a lot more color than 'Silver Swan' - a mostly creamy yellow base with just a touch of green along the leaf midribs. New growth comes in with a reddish tint and in my area, the entire plant colors up brightly (red, pink, orange) during cold weather. The flower bracts are a pale chartreuse yellow on a pretty compact (18-24") plant.

Placed side by side, IMO the two plants look nothing alike. If you were trying to match the Silver Swans, I doubt you would be satisfied with Ascot Rainbow, although I think it is a stunning plant all on its own. Silver Swan presents a very 'cool' appearance that combines great with darker colored foliage and slivery blues. Ascot Rainbow looks best with warmer colors - golds, bronze, toffee tones.

If it's flopping so that the center is bare and the blooms are faded/gone you can cut it back as hard as you'd like, it'll start growing again and bloom in 6-8 weeks. Mine do the same thing but I'm probably 2-3 weeks behind you--mine are blooming and standing up nicely right now....

I grew Echinacia/coneflowers from seed back in 2009/2010 the first time I tried winter sowing and had good germination. I didn't expect blooms the first season based on what I'd read on the WS forum. The plants bloomed the second season but that's in my zone 6 garden, which is quite a bit warmer than your Z3. It's no more than a guess but perhaps they take a season or two longer to bloom in your zone.

Good luck & hope you see blooms in the very near future.

Echinacea blooms the 2nd year from seed for me too. I am just getting the first flowers coming out now.

If your plants are 3 feet tall, you must have blooming stalks shooting up. Aren't there buds at the top?

I am green, or orange as the case may be, with envy! So pretty, and I supposedly don't like orange. Apparently this year I do. A few seeds sprouted, but something thinks these plants are YUMMY. Think it's partially my fault for the probably-too shady spots where I put them. Wrong romantic notions about them twining all over this fugly metal thing... Yours looks very sunny and dry, thus happier. Very nice. Did you just forget the name, or did a critter grace your garden with the seed? Maybe they prefer to be "fugitives?" Ha!

I agree, nothing more is needed. A large pot or urn in front of the post with something tall, or shepherd hook with pretty, bulky hanging basket could add interest at a higher level, break-up the shelf-type appearance of everything being the same height without crowding at ground level.

The beautiful JM deserves a better spot, to be the focus in a focal point.

Right around the corner, near where the hose is laying, might be a good place for a tall, columnar evergreen entity, to block the view (and winds) of your front yard from that parking lot, and the reverse - while softening the appearance from the curb - I think.

But you live IN the house, not at the curb. What is available to view from the large, lovely window? Looks like the yard is spacious enough to create focal points far enough away from the house to be seen from inside, that do not block the view out of the window(s.)

Making any decisions from this angle alone would likely be regrettable. Such a beautiful house, less is more, don't hide it, unless you're doing it from much farther away from the house, to include the yard in the privacy, not just the house.

and you would remove individual flowers.. not the whole stalk at once ...

Nope, do remove the whole stalk, down to the lower leaves (usually around 1foot tall) as soon as the main spike of flower has died back - more side shoots will appear for a later show around late August (if you give them a little extra food and water)

Veronica cultivars have not been long-lived in my garden, so I wouldn't be surprised if 'Blue Bomb' bombed.

Years ago I bought Sunny Border Blue, which was named Perennial plant of the Year in 1990-something, and it was pretty the first year. But it grew weaker each year, instead of expanding, to the point where I shovel-pruned it.

There is one Veronica 'Icicle' left in the front garden that has lasted a few years, I like the delicate white spires of this plant.

Beauty is in the eye of the beholder, and I think this plant is absolutely lovely. Unfortunately my attempts at growing veronica have been dismal failures.

I would vote for any type of hydrangea or hosta for the ugliest plant ever, although I know these are popular with a large majority of gardeners.

why replant what needs to be moved... wont it be going back????

two choices ....

make a nursery bed .... even just a pile of wood chips.. dig up plants.. nestle them in.. and 'hold them over' for the week or two of the project ... replant.. the spread mulch .... this plan might seem slightly backwards.. to order the finish mulch first.. but is brilliant.. if i say so myself.. lol ... make it part of the project and have him deliver and place it.. where you need it for the storage ... sorta like nurseries.. who bury ball and burlaps in mulch ...

or use plastic grocery bags .. dig plant... insert in bag .... carry to holding area in full shade ... set down.. open bag flat .. and let them lay there for the duration ... pick up.. and replant after it is all done ... throw bag away .. water and mulch ....

take lots of pre and post pix ....

good luck

ken

ps: might be an interesting NEW post about how others have 'held plants over' ... if you dont address it solely to me.. lol ...

I love this plant!! I know it can be a problem but I find it behaves rather more nicely if you stress it a bit. More sun, less water and spreading growth slows dramatically. it doesn't try to take over the world.

No reason why it shouldn't respond to RoundUp or any other broadleaf herbicide if you are in a position to use such.

A non-chemical alternative to Roundup might be vinegar. I use regular white vinegar as a weed killer in my garden because I don't like using harsh chemicals. Vinegar kills whatever it touches so I'm careful to pour it slowly on the weeds--briars, crabgrass, dandelions, poison ivy--and avoid getting any on my plants. I pour it on both the foliage and close to the stems at ground level.

I planted a couple of Branford Beauty a year or two ago. They are very small still; at this point they have more of the low/wide look of a JPF, so I'm not sure yet hom they'll look longterm.

I have never seen this plant showing any blackened leaves. I have it in my very dark shade hosta garden. It actually reseeds and I have had to remove the babies to other areas. In 5 years I have 5 new huge plants.

@katusha, yes, I do this with several plants and it works very well...Brunnera, Pulmonaria, Lady's Mantle, Bachelor's Buttons, Husker's Red Penstemon, variegated Symphytum, to name only a few off the top of my head. Keeps things fresh-looking and healthy, as many spring flowering plants can look ratty after bloom. Sometimes I wait until the plant splays, showing the basal growth coming up and sometimes I just shear it right to the ground. I have never lost a plant this way.
