Gardeners' Notes:


On Jul 25, 2011, JenDion from Litchfield, NH (Zone 5b) wrote:

This Ajuga has fantastic texture and sheen. In my zone 5 garden it has been a slow grower, until established (2-3 years) then seems to spread a little more reasonably, but no where near invasively. Mine gets full sun from noon or 1pm until sundown.

This one is high on my list of favorite Ajugas, though, at times, it can be a bit moody. Having some in several areas assures having backup, and it does spread well. Blooms in May in my garden.

Lovely groundcover. Slow grower for me. Unless I plant it underneath a very large plant, it won't survive the heat. Not easily found in my area, I try to get a couple of 4" pots when I'm lucky to find it. The foliage is shiny and feels very leathery.

This plant does very well, or maybe too well, in my zone 5 area. It grows very rapidly however it does allow some grasses to grow up through it. Some would call it invasive. I guess depending on where you want it, but you do have to control it.

I acquired tis at a local nursery ere in theb Catskills. I have it growing in a bed surrounding an Alberta Spruce, with crocosima Lucifer popping up through it. Very attractive. Sturdy enough to fight off the goutweed problem, but nowhere near as invasive as most ajuga. Beautiful color and sheen.

This groundcover is growing around Sum and Substance Hosta. The contrasting colors are nice. The Mettalica has a glossy sheen, indeed, like metal. In this situation, it has spread VERY slowly, which is OK with me. As it has become more abundant, the blue flowers in Spring are very attractive.
