I planted two of these last summer--LOVE the color combination and would have gotten more but I was unsure of the zone ratings. Most say zone 5. That hasn't stopped me before, but I usually don't go whole hog until I'm sure they will work here. They looked wonderful and bloomed for quite a long time (I kept them deadheaded). It's too early for them to bloom yet this year, but the foliage is lovely - a full but tidy mound of beautifully variegated leaves. If they bloom anywhere near as well as they did last year, I'll be extremely happy.
Update - late June - everything is 3-4 weeks behind here because of our weird spring, but these are starting to bloom now. There are a lot of buds! In spite of 2-3 times normal rainfall, these do not appear to be unhappy like a lot of my other... read more

I planted 3 plants in zone 5b last year (2011). All 3 came up healthy this year, and have bloomed prolifically all summer. However, one plant came up completely unvariegated, and the other 2 have portions that are unvariegated.

When healthy, "Thunder & Lightning" is a lovely massive ground cover. However, in the wet and humid conditions of THIS summer, the plants have been prone to a powdery mildew and severe leaf rot. I've already had to completely replace one plant. Several plants are rotting away, while a few others seem to be maintaing their shape and flowers. Not sure if I would plant these again.
