Golden Rule™ - St. John's-Wort - Hypericum This is the solution to many landscape challenges. An excellent groundcovering subshrub for shade, Golden Rule 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 12" tall
Honshu Kerria: Every garden deserves this splendid Kerria! Hard to find but so easy to grow, this delightful little shrub offers big 2-inch golden-yellow blooms most heavily in spring, and intermittently in summer and fall.
Not as invasive as the Blue Moon variety, I think this Amethyst Falls Wisteria would be beautiful framing our back patio (up the colums) with the lovely fragrant, vividly blue flowers hanging down just into view and blowing in the breeze from spring all through summer.
