Portulaca (Portulaca grandiflora), commonly called moss rose, is a succulent- stemmed annual built for hot, dry, low-fertility conditions where other flowers fail. Its silky, rose-like blooms open in full sun and close at night or on cloudy days. Excellent for slopes, rock gardens, containers, and parking-strip plantings where irrigation is limited. One of the easiest annuals for neglect- proof summer color.

Camp County, Texas is in USDA Zone 8b. The average last spring frost is March 14 and the first fall frost is November 12, giving you a growing season of approximately 243 days.

At an elevation of 285 feet, Camp County receives approximately 61.3 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 92°F, providing good warmth for Portulaca during the growing season.

Ample rainfall means less supplemental watering, but ensure good drainage to prevent Portulaca root diseases.

Portulaca 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.

Portulaca needs ~1,140 GDD — county provides 4,617 GDD Excellent fit

Growing Tips for Portulaca in Camp County

Direct sow Portulaca outdoors after March 14 in Camp County when soil has warmed and frost danger has passed.

Sandy soil in Camp County dries quickly — mulch Portulaca with 2-3 inches of straw and water deeply 2-3 times per week rather than lightly every day.

General growing tips

Direct-sow after last frost once soil warms to 65°F, or start indoors 4–6 weeks before last frost. Seed is tiny — surface sow and do not cover. Thin to proper spacing after germination. Thrives in poor, well-drained soil; rich or wet soil produces lush foliage but fewer blooms. No deadheading required — plants are self-cleaning. Double-flowered varieties hold blooms open longer in overcast conditions.
