Rock Skullcap Plant Care

Rock Skullcap (Scutellaria saxatilis) belongs to the Lamiaceae family within the Scutellaria genus. Rock Skullcap is native to the southeastern United States.

Rock Skullcap displays a low spreading groundcover growth habit, reaching up to tall with a spread of approximately . Rock Skullcap produces small tubular flowers in shades of blue, purple, or pink.

Rock Skullcap thrives in full sun to part shade.

Well-draining sandy loam with added organic matter. Good drainage is essential for Rock Skullcap to prevent waterlogging, which leads to root rot and fungal issues.

Choose a spot with full sun to part shade and well-draining sandy loam with added organic matter. Avoid low spots where water collects after rain.

Plant container-grown or balled-and-burlapped shrubs in spring or early autumn, setting the root flare at soil level, and water well after planting.

Prune Rock Skullcap while it is dormant in late winter: first remove dead, damaged and crossing branches, then thin lightly for shape.

If it flowers in spring, prune right after flowering instead so you don't remove next year's buds. Never take off more than about a quarter of the shrub in one year.

Water deeply in late autumn before the ground freezes, and spread a 5–8 cm (2–3 in) layer of mulch over the root zone, keeping it away from the trunk.

Young and container-grown shrubs need extra protection: roots in a pot freeze much more easily than roots in the ground.

Rock Skullcap can be propagated through seeds, division of root ball, softwood cuttings. Similar propagation techniques also apply to caucasian skullcap plant care, which shares the same genus.
