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.

Terry County, Texas is in USDA Zone 8a. The average last spring frost is April 6 and the first fall frost is November 7, giving you a growing season of approximately 215 days.

At an elevation of 4,751 feet, Terry County receives approximately 48.5 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 99°F, so Sedum (Stonecrop) may need afternoon shade and extra watering during peak heat. Sandy soil warms quickly in spring — great for early planting — but Sedum (Stonecrop) will need more frequent watering and organic matter to retain nutrients.

Sedum (Stonecrop) Heat Requirements (GDD)

What are Growing Degree Days (GDD)?

Growing Degree Days measure the total warmth your plants receive during the growing season. Think of it as a "heat bank" — every day above 50°F deposits warmth that helps your plants grow.

Each plant needs a certain amount of accumulated heat to mature. If your county provides more GDD than the plant needs, it's a great fit. If it's close, you may want to choose faster-maturing varieties or start seeds indoors to get a head start.

Sedum (Stonecrop) needs ~1,819 GDD — county provides 5,213 GDD Excellent fit

Growing Tips for Sedum (Stonecrop) in Terry County

Direct sow Sedum (Stonecrop) outdoors after April 06 in Terry County when soil has warmed and frost danger has passed.

Sandy soil in Terry County dries quickly — mulch Sedum (Stonecrop) with 2-3 inches of straw and water deeply 2-3 times per week rather than lightly every day.

With summer highs reaching 99°F in Terry County, provide afternoon shade for Sedum (Stonecrop) and water deeply in the morning.

General growing tips

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.
