Gold Crest Bluebeard, Spiraea, Caryopteris

Caryopteris x 'Gold Crest' PP32310

You can grow this award winning Bluebeard for its foliage alone! The new bright yellow spring foliage retains its color throughout the growing season even in the hot and humid south. In late summer and fall, dense whorled clusters of deep violet-blue, nectar rich, tubular flowers are held above and among the wonderfully contrasting foliage. Gold Crest Bluebeard, a Caryopteris hybrid, was selected for its heat tolerant brilliant foliage, for its dense compact habit, and its pollinator attracting flowers. In zone 6 Bluebeard tends to act more like a clump forming die-back perennial and becomes more shrub-like where winters are milder, although, it benefits from a hard late winter or early spring pruning since it flowers on new growth. Somewhat drought resistant once well-established and prefers a sunny site in a well-drained soil for optimum vigor and flowering. Won Best Pollinator Friendly Perennial for the Southeast in 2019 at the UGA Trial Gardens and was rated above a 4.5 out 5 at both Penn State(2021) and Mississippi State(2020) trial gardens as 2nd year perennials!

Spikes of 1" blue to purple tubular flowers that are tipped with white on the lower two petals are produced over an extended period beginning in mid to late spring into late summer if moisture is adequate. Heartleaf Skullcap, Scuttelaria ovata, is a shade-loving rhizomatous groundcovering evergreen native perennial with heart-shaped foliage that emerges a purplish red to burgundy and maintains a tinge of that coloration even at maturity. This species is widely distributed throughout much of central and eastern US and extends into both Canada and northern Mexico. Heartleaf Skullcap is tolerant of dry shade once well-established which is one of the more difficult combinations for plants to thrive in. It will be most apt to flower longest under average moisture conditions. The flowers attract hummingbirds, butterflies, and other garden beneficials.
