Blue Penstemon Seeds Growing Guide
• Sowing: Sow seeds on the soil surface and lightly press into moist soil; do not cover, as light helps germination. Cold stratify for 2–4 weeks before planting to improve germination.
• Location: Full sun.
• Soil: Well-drained, sandy or rocky soil with low to moderate fertility.
• Water: Keep soil lightly moist during germination; once established, water sparingly and avoid waterlogging.
• Care: Hardy perennial that prefers cool, dry conditions and good drainage. Remove spent flower spikes to encourage longer blooming and maintain strong blue floral displays that attract bees, butterflies, and hummingbirds throughout the season. 🌸🐝🌿
