When to Plant Sedum (Stonecrop) in Frederick County, VA

Sedum (Hylotelephium spectabile, formerly Sedum spectabile) is a supremely tough, drought-tolerant perennial prized for its late-season interest. The flat-topped clusters of starry flowers open pink in late summer and deepen to copper-red as temperatures cool, remaining attractive well into fall and providing seed heads that feed birds through winter. Succulent foliage emerges blue-green in spring, is handsome all season, and turns bronzy after frost. Remarkably adaptable — thrives in poor, gravelly, or sandy soils where other perennials struggle — and virtually maintenance-free once established.

Frederick County, Virginia is in USDA Zone 7a. The average last spring frost is April 24 and the first fall frost is October 18, giving you a growing season of approximately 177 days.

At an elevation of 743 feet, Frederick County receives approximately 44.4 inches of rainfall annually with predominantly silt loam soil. Summer highs average 88°F, providing good warmth for Sedum (Stonecrop) during the growing season.

Growing Tips for Frederick County

Plant divisions or container plants in spring after frost danger passes, or in early fall. Excellent drainage is the primary requirement — upright border sedums will rot in wet, heavy soils over winter. Lean soil actually improves performance; avoid over-fertilizing which causes floppy stems. Tall cultivars (Autumn Joy, Matrona) may need light staking in rich soil. Divide every 3–4 years in spring when centers become sparse. Deadhead selectively — leaving seed heads through winter extends ornamental interest and feeds goldfinches. Very low water requirement once established. Year 2+ plants reach full clump size and peak bloom display.
