Hypericum calycinum 'Brigadoon'
(Aaron's beard, St. John's wort)
'Brigadoon' is a new St. John's wort with brilliant chartreuse-yellow foliage that looks great next to dark-foliaged plants. It grows 12 to 16 inches tall and spreads quickly to about 2 feet wide, making it an excellent groundcover when planted in groups. In the sun, the small, oval leaves turn a dazzling orange-gold. The fuzzy, rather inconspicuous yellow flowers appear in midsummer. 'Brigadoon' tolerates heat, most any type of well-drained soil, and shade.
