If you are here in the summer, look closely at the flowers of this plant and you'll see that the yellow petals appear to be topped with a bright yellow pompom! These tiny filaments are carrying the pollen that will stick to any bee or butterfly that stops by to sample the flower's nectar.

BLUES FESTIVAL™ St. Johnswort is a cultivar of a north American native plant that thrives in hot dry conditions. It has bright yellow flowers which contrast against the bluish-green foliage and it grows to form a low mound about three feet high and wide. This plant is tough and can handle, deer, salt, and drought and yet requires practically no maintenance. All it asks is full sun and very well-drained soil in return.
