Gardeners' Notes:

Positive DonnaMack On Dec 23, 2009, DonnaMack from Elgin, IL (Zone 5a) wrote:

Absolutely beuatiful, and not at all invasive in zone 5a. Goes with roses, peonies, grasses, what have you. Deadheading results in bloom until frost. Striking yet subtle. One of my favorite plants.

This catmint has done very well in our clay-based soil within the drip line of a monster silver maple - I don't think I could ever have enjoyed the cottage-garden flavor of a catmint without this one.

This is not to recommend it as a shade plant, because the passage of the sun through neighboring trees gives it about a half day of sunlight in early summer, which lessens as the sun's path changes with the season. Also, a lot of compost was dug in at the time of planting.

Black Beauty lily has been growing up through this catmint, and we suspect it is able to flower even with woodchucks around because the aromatic leaves of this catmint mask its tell-tale odor from Woody.
