I think that there are some that spread by seed, and some that don't set seed. That may be the difference in people's experience. They are hard to remove if you don't like them where you plant them, as the tiny baby offset bulbs would have to be sieved out of the soil or constantly weeded or they come back. But they are reliable and very pretty in their time.
My fall planted persicaria is only about 12 inches high and it is starting to send out short flower buds. Really curious to see how large it gries this year in my amended clay soil. I had a hard time finding it and ended up getting it from arrowhead alpines. I think lazy s carries it as well.
Persicaria polymorpha did fabulous for me for a few years but lately seems to struggle. I have a small piece I may try to salvage and replant. I'm not sure why it suddenly became unhappy. Do you know a good mail order source? I'd like to try another one.
Thanks for asking this question as I started a mix of Japanese primula seeds and have one of this miniature which I really like. Now I have a name for it. I read online that p. Kisoana spreads by stolons and self seeds. My singleton has not spread at all probably because it is growing in packed soil on the north side of the house and later gets covered by hosta leaves. Think I will move it to a better location.
Rouge, my cordifolia made it through the winter and is spreading but it definitely doesn't look as vigorous as that or does it have such large flowers. I'm afraid my conditions are more challenging. Mine are trying to compete with Maple roots.
I think I am going to buy a few of those 'Sugar & Spice' and offer them a better position than the last batch I planted. Further away from the tree roots.
Oh, one of my favorite plants! I started out with two small sections 25 years ago; now there are so many I use them as a fill-in groundcover. Subtly variegated-leafed whitish and purple-flowering plants have joined the collection. And I am trying to get my hands on some B. ochracea, too. Your neighbor's patch looks nice peeking out from under the conifer.
lilsprout, you got my quirky sense of humor. Most people aren't familiar with the endlessly repeated adage of "3 years..
But I should have answered the question, which isn't as simple as, is it enough sun?... For your columbine, just fine, & having a preference for moist soil. While the daylily in bloom, likely gets enough sun, if it's until 2:30.
Whereas, I'm not even familiar what zone ne Ohio is & can say if your lavender can survive winter. Some may make it with protection, to zone 5? possibly with protection & well drained soil & if it's a hybrid...That can be a really tough question, as its a matter of plant hardiness & your zone & how much winter protection & if the soil drains well enough in winter & things to do, such as that, but does prefer full sun exposure & not severe exposure to elements of winter.
Shasta daisies can be an odd lot, depending on if its a newer hybrid, or just regular old ordinary, tried & true, 'Alaska'. Others can be picky about too much or not enough water in summer & soil , not only grown in, but planted into & I've seen some thrive in afternoon sun, where other cultivars may just melt, in the same conditions... & some drought tolerant in hot afternoon sun & others constantly thirsty, with afternoon shade!
Try giving your daylily some fertilizer and make sure it gets adequate water, afterwards.. If it still looks sparse, then maybe try another more vigorous one. There are thousands to chose from, just like Hosta selections.
Some daylilies entirely lose leaves in winter and others may have a few short ones, waiting for spring to arrive (at least down here where I'm at, in zone 7/8) & with the past winter, the ice age, from... I'd better not say!
hth you decide about what to expect, & when planning & planting in the future.
Full sun plants only require a min. of 6-8 hours of direct sunlight. I had Lavender, Blue Flax, perennial Foxglove, perennial Snaps, Dianthus, Thymus serpyllum, Daylily, Chives, Daffodil, Sedums, etc., that did great beneath a Cherry tree. They received sun from a.m. through about 2-2:30 pm and then filtered light to med. shade. This bed never got any amendments except leaf fall....soil was mostly sandy/gravelly and infertile towards the perimeter, which for the most part fit about everything planted here.
I grow polychroma, "bonfire" and 'First Blush'. Bonfire will spread around a bit where it is happy, but I like it, so I don't mind. Polychroma would take over the garden if allowed, but I still like it. Deadheading it would prevent it's world-conquering tendencies. First Blush is a lovely plant - tidy, compact and always pretty from early spring through late fall.
I also really like E. grifitthii - it spreads, but only through the bed where it is planted. It is easily controlled.
E. amygaloides 'purpurea' is a spreader too, but easy to control here.
Looking through my lists, it is interesting how many I have tried and yanked because of their aggression or they failed in our climate.
Yes, it is possible that the Pirouettes are better behaved. A little self seeding never bothers me. I do tend to mulch heavily, and they are growing under a camellia where I rake up the spent flowers in the spring while the begonias are still dormant. So it is also possible I am interfering with self-seeding. Nevertheless, they are truly lovely in a very special way. I really like this plant.
I would venture to guess, if your soil is depleted of sufficient nutrients & they haven't been divided often enough, & you cut for long stem bouquets, you get reduced flowering such as seen above in photos.
Long stems being cut annually, is not nearly the same as deadheading, which is removal of just the tip, where the flower was...
That isn't to say, heard of people with extremely rich soil, mowing them down after blooming, and getting huge flower displays, the following year. So, there is something that just isn't right, about those three, going on & can't dig in your soil, don't know how much you or how many stems you cut off, or the last time these were divided.
Perhaps, after going dormant in autumn, carefully dig ( as the roots are brittle) & see what's with the soil, & while you are at it, divide them to rejuvenate them. Then add a slow release fertilizer when replanting & amend the soil too...
Sometimes I get request for seeds from different places and to go through my disorganized mass of seeds and make some sense out of them, label and get them to the post office eats up my day. It is at some of those times , That I am made glad that this is not my business. All I want to do is traipse through the hill and dale collecting seed, feeling connected.
At the end of summer, some of the seeds at a store across the street, will reduce them to only just pennies a pkt. Including; Delphiniums, Canterbury Bells, Columbines, Perennial wildflower mix, etc..
Then , recycle a padded envelope & pay the least, using first class rate... to U.K.
Apart from that, collect what I can, from my own garden...
Just requires a little patience, of a few months.
Rouge- that is a really nice plant! I'm glad to hear it came back as well as it did, good for you!
I'm polygonatum free right now but when I go visiting and see plants I've given away I wonder why.... But then I guess you can't grow everything lol
Help identify
Camassia maybe Blue Melody due to the variegated foliage.
