Gardeners' Notes:

Third time must be a charm in my Zone 5 garden. The first two times is just disappeared or melted away, like one other poster has stated. The last time I put it in a protected area, morning sun only, near a large shade tree, and behind a picket fence. Lime Rickey did very well this past summer and even looks good during the mild winter we're having. I believe it must be protected from too much sun and winter winds.

Over the years, this heuchera has completely disappeared. Unlike the other heucheras in my garden (I'm a heuchera addict!) this one never thrived, growing smaller instead of larger each season. I could see it dwindling before my eyes, no matter what I did. It was planted around other heucheras that have done just fine. In addition to its weak spirit, it was also occasionally mauled by some kind of varmint passing by at night. I don't know why--all my other heucheras seem deer and rabbit resistant. Maybe because this one is the color of lettuce it was hard to pass by? I will be trying "citronelle" this year to replace this one. I have heard that heucheras by Thierry Delabroye may be more robust than this plant. Here's hoping!

I planted this in a partly sunny north location in the middle of July 2005 and it is growing and doing very well. I planted a hosta at the same time and it is dying, which surprises me since hostas are supposed to be so easy to grow.
