Impatiens (Impatiens walleriana) are the go-to annual for shaded beds and containers. They produce a continuous carpet of flat-faced blooms from transplant until frost, needing little deadheading. Their preference for consistent moisture and part-shade makes them ideal under trees and along north-facing borders.
Rains County, Texas is in USDA Zone 8b. The average last spring frost is March 13 and the first fall frost is November 16, giving you a growing season of approximately 248 days.
At an elevation of 363 feet, Rains County receives approximately 66.1 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 95°F, so Impatiens may need afternoon shade and extra watering during peak heat. Sandy soil warms quickly in spring — great for early planting — but Impatiens will need more frequent watering and organic matter to retain nutrients. Ample rainfall means less supplemental watering, but ensure good drainage to prevent Impatiens root diseases.

Impatiens 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.

Growing Tips for Impatiens in Rains County
Direct sow Impatiens outdoors after March 13 in Rains County when soil has warmed and frost danger has passed.
Sandy soil in Rains County dries quickly — mulch Impatiens with 2-3 inches of straw and water deeply 2-3 times per week rather than lightly every day.
General growing tips
Start seeds indoors 8–10 weeks before last frost at 70–75°F; germination requires light — do not cover seeds. Transplant after last frost once nights consistently exceed 50°F. Water regularly — wilting causes bud drop and they rarely fully recover the same flush. Watch for impatiens downy mildew (IDM); consider New Guinea impatiens as a resistant alternative in affected regions. Pinch tips at planting to encourage branching.
