This Heuchera is very attractive and has proven a lot hardier than some of my other varieities. It did not heave this winter, as many others did and it survived deluge conditions in the spring and drought conditions in July. It gets late afternoon sun in my garden.

I'm adding a note only to point out that it has grown well through three winters now in my Zone 3 garden; and last winter was definitely a "test" winter, for sustained cold. It is in a somewhat sheltered place - the wind doesn't get to that area, and it has consistent snow cover. The soil is sandy loam, and water is consistent. In my opinion, zone information is only one of several factors that affect plant survival, and often not the deciding one. I concur with the positive comments of others - fascinating foliage that changes shades slightly as it matures, and always a strong, healthy mound. Whenever I go by its garden, it catches my eye first, before all other plants. Plants with other colors of foliage make excellent companions.

'Amethyst Myst' is superior to the old 'Palace Purple' it is one of my favorite Heucheras and I grow close to two dozen of them. Has really nice color that doesn't fade and it is a more compact grower.
Make sure you bait for slugs if they are a problem in your area.
Otherwise the plant is care free except for watering in severe drought.

I have several of these alum roots, and I really like them..even tore out my Palace Purple to replace with the Amethyst Mist (those were seed grown and quite variable, too much khaki green for my taste). I have them planted in the outer drip line of a med. size tree, a fairly dry area and they are thriving. They survived a very cold winter (but had lots of snow cover) and a very hot, dry summer.

This heuchera seemed more tender than others I have grown and only made it through two Catskill winters. The one in more sun did better than the one in more shade. It also seemed vulnerable to "watering" by the dog, which browned it up pretty badly. It was gorgeous while it lasted, though..

I enjoy the color the leaves add to the winter garden. The plants do not go dorment in the Atlanta area. They are very versatile too. They can be grown in partial shade to sun; borders, beds or containers.
