"There are a few different white yarrows, but I think most of them are aggressive. I have one that looks like tall baby's breath (gorgeous as a filler), but is a thug. I pull most of it out, as soon as it shows, and it still fills in well."
"I agree with Julie. I love spireas. They're hard as nail, and come in dozens of sizes/colors, from old bridal wreath to ground covers. Anthony Waterer and Goldflame are two that have done well for me."
I often buy my plants at end of season specials ( I think it's the best time to plant perennials, and they're the cheapest, then). Last year, I bought an "assorted lily mix" for a terrific price and tossed in some late…"
"I love my hori hori knife. It's a trowel that's serrated on one side, sharpened on the other, has measurements down the blade. Makes it easy to plant small perennials in my hard clay soil, and cut small roots (which I have loads of, with 3…"
"Diddiloo, I found this on zones for Sweden;
In Sweden and Finland, at sea level to 500 metres, zone 3 is north of the Arctic Circle, including cities like Karesuando, Pajala and Rovaniemi. Kiruna is the big exception here, which being located on a…"
"Dry shade is a challenge, especially in a short growing season (like 4!). I'm told epimedium likes it there, but I've never had good luck with those. I have large maples (with their shallow roots), and have had success with lamiastrum,…"
"Jan, up here in the 'frozen north" of zone 4, they last the summer (if I don't let them dry out too much...they're under maples). I thought they were spring flowers...this is the first year they've rebloomed for me. It must…"
"Julie, it's called celandine poppy... yellow, with a big flush of blooms in the spring, then blooms off and on during the summer, with a very cool seed pod. They do reseed but not invasively. I love 'em too."
"There are tons of shade plants for Wisconsin. Besides the ones you've mentioned, I have blue lobelia, lysimachia, bishop's weed (a thug, but great where nothing else will grow), woodland poppies, pachysandra (wonderful ground cover, daffs…"
"Deer and rabbits deposited manure into my gardens and lawn. Still to pull last of veggies and put away to compost. What would happen if I just left it in garden to decompose over winter, pea plants I mean?"
