About Me Getting Started
Planted this little guy a couple of years ago as filler/weed barrier in two gardens, one in full sun, the other shade in the morning and sun in the afternoon. Both spots are doing well and the first year the plant starting spreading as i expected - not gang busters, but slow and steady while maintaining a healthy look. The spreading was slower than I had hoped it would continue this year, but probably to the very unusually wet spring we had in Denver this year (2015). Still looks great though, even in a garden that received inches more moisture than it is designed for.
To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.
