Stunning the second year!

These didn't bloom at all the first year, just established their nice rounded mounds of lance shaped leaves. They were cut back into low mounds, then we had a super brutal (for us) cold bout, and I feared they might not make it. Not to worry! They grew rapidly this spring and have burst into stunning displays, covered by floating double yellow flowers. I'm looking forward to how they do going forward. I also intend to plant more now that I've seen them.

These flowers did even better than I expected. They are so pretty and by deadheading, I'm getting even more blooms. Super easy to care for.
