#ProPlantTips for Care:
Wallflowers do well in full sun and partial shade locations, favoring afternoon shade to give them some relief from the intense sun. Plant in enriched well-drained soil that is alkaline and on the drier side. Provide moderate amounts of moisture, letting plants dry out slightly between waterings. Established plants are very xeric and low-maintenance! Deadhead the flowers after they fade and trim the plants in the early spring before new growth emerges.
- Full Sun & Partial Shade
- Well-Drained Alkaline Soil
- Low Moisture Once Established
- Deadhead To Tidy Up The Mounds
- Heat-Tolerant Perennials Or Annual Accents
