Like overgrown buttercups, Chrysogonum virginianum 'Pierre', commonly known as Goldenstar, resembles thousand of small butterscotches atop pillows of green. This
low growing,
herbaceous mat-forming plant, is similar in structure to
Ajuga.
Prized for a
long blooming time, the star-shaped
sunny-yellow flowers (1- 1 1/2 inches long) dot mint-like foliage in early spring and continue sporadically throughout the summer. Superb in terms of both spread and degree to which it propagates flowers, Pierre creates a delightful ground cover or edging in any perennial
border.
Though Pierre does bear fruit, it is non-ornamental. The real focal point of this plant is the
semi-evergreen, jade-green opposite leaves that are round-toothed along the edges, and reach 1-2 inches long. Excellent as a facer in naturalized gardens, 'Pierre' is especially useful for
partial shade borders where, when in bloom, the flowers resemble tiny night lights in the darker shade.
With a limited tolerance of
foot traffic and a fair to good
weed-suppressant rating, as well as a willingness to tolerate a
wide range of well-drained, moist soils, this hardy perennial is an almost fool-proof choice.
Because it spreads indefinitely, you can plant Pierre in large areas where you need expansive coverage and have the added benefit of long-lasting bloom season with golden blossoms polka dotting a carpet of green foliage.
Interesting Facts Pierre is native to North Carolina and as such, is lovely in woodland garden scenes.
Things to Note If grown in
full sun, Pierre may need more water.
In
zones 8-9, this plant will require afternoon or full shade.
Gardener Tips Pierre is a perfect gentleman combined with
evergreen and
deciduous shrubs, small
trees,
ferns, and
herbaceous perennials.
Black Eyed Susan and
Mary Todd Daylilies are a lovely duo to join with Pierre for a sunny-side up display of blossoms.
