Hypericum calycinum 'Brigadoon' (Aaron's beard, St. John's wort)

Hypericum calycinum 'Brigadoon'

Aaron's beard, St. John's wort

A bright new foliage color for shady sites! Golden yellow, oval leaves with reddish edges support 2" gold flowers with pincushion-like center clustered stamens in late spring and early summer. You will hardly notice the flowers in the sea of gold foliage. This plant is most content in cooler areas away from drying winter winds, although once established it is quite tough.

Aaron's beard, St. John's wort Interesting Notes

Hypericum translates as "above a picture", referring to the fact that in ancient cultures, cuttings from members of the genus were hung above pictures to ward off evil spirits. Calycinum translates as "with a conspicuous calyx", referring to the portion of the corolla structure that lies beneath the yellow petals. - OSU Pocket Gardener

We are thrilled to see our 1998 introduction finally making its way into the mainstream trade. We were captivated when we first saw this gold leaf mutation of Hypericum calycinum on a 1995 visit to Oregon's Briggs Nursery. The plants were sent home with us and H. 'Briggadoon' was born. H. 'Briggadoon' makes a slowly stoloniferous thick groundcover of golden foliage on short arching 1' stems. In mid to late summer, the clumps are topped with yellow St. John's wort-like flowers...perfect for brightening a lightly shaded spot in the woodland garden. In colder climates, cut the old stems to the ground in early spring for best results. - Plant Delights

Sometimes commonly called Aaron's beard or creeping St. John's wort. Plants of the genus Hypericum (some species have been used since ancient times in the treatment of wounds) were apparently gathered and burned to ward off evil spirits on the eve of St. John's Day, thus giving rise to the genus common name of St. John's wort. - Missouri Botanical Garden

RE: Sun exposure - we have had success with this plant in full sun when the soil is kept moist but not sopping. It can wither or burn in direct exposure to the hot afternoon sun. The sweet spot for 'Brigadoon' is either dappled light throughout the day, or, if full sun exposure, it has just a few straight hours in the morning. The golden foliage thrives best when those light conditions are observed and when the soil is kept evenly moist. Its hardier parent, H. calycinum, can take full sun exposure including afternoon sun.

Hypericum calycinum 'Brigadoon' Growing and Maintenance Tips

In our experience, 'Brigadoon' performs best in rich, moist soils and partial shade, and may burn in the full summer sun of zone 7. 'Brigadoon' is stoloniferous and may be propagated by seed, division or terminal cuttings. Prune old wood in late winter to promote new flush of leaf color. Easy to grow and low maintenance. Best used as a groundcover or in mass plantings.
