Hypericum calycinum
Hypericum calycinum
Common Name: St. John's wort

A widely used and attractive evergreen groundcover which is dense, but not invasive. Deep green, oval leaves and 2" gold flowers with pincushion-like, center-clustered stamens in late spring and early summer. One of the nicest groundcovers when in bloom. Most content in cooler areas away from drying winter winds, although quite tough once established.

Height: 15-18 Inches
Spread: 24 Inches
USDA Hardiness Zone: 5-7

Pycnanthemum muticum
Pycnanthemum muticum
Common Name: clustered mountain mint

We give up! So many of you claimed this mountain mint to be superior to Pycnanthemum virginianum that we decided to try it for ourselves. We love it! Its leaves are broader and more lustrous, the bracts are silvery and very showy, the flowers are pinkish and its habit is more compact. Nicely aromatic. This native is happiest at the wood's edge, so it is excellent for a naturalized border or woodland garden. Mountain Mint is one of the best nectar sources for native butterflies, so butterfly gardeners can't do without this one. Our bees go crazy for it, too!

Height: 2-3 Feet
Spread: 2 Feet
USDA Hardiness Zone: 4-8
