Description

An excellent groundcovering subshrub for shade, Golden Rule® hypericum has colorful orange new growth and attractive yellow foliage. Unlike 'Brigadoon', it does not revert. Yellow summer flowers up to 2" across add to its appeal. Although it is not as aggressive as the green-leafed varieties, it will benefit from a trimming one or two times per year.

Growing Tips

Tip die-back is possible in colder climates; however, this is readily pruned away and plant regenerates quickly in spring. Benefits from periodic rejuvenation pruning.
