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.

Fiery orange, yellow, deep cobalt blue along with reds and near purples adorn the large showy flowers and bracts which are produced mainly during spring and fall as well as in winter in areas with mild tropical climates or where grown indoors. In almost all regards the Narrow-Leaved Bird of Paradise resembles its more common cousin the Orange Bird of Paradise, although this one is more resistant to drought and has reduced its leaf blades to the point where, once the plant is mature, only the narrow, rush-like, blue-green petioles remain with which to endure the desert conditions from which it arises. It is considered to be more drought resistant and prefers well-draining soils. Makes for an unusual container specimen or use it similarly to the Orange Bird of Paradise as an informal hedge, shrub, or specimen plant. Item# 11139
