Full details
The Thompson & Morgan Salvia Verticillata 'Purple Rain' is a hardy perennial for gardeners seeking naturalistic charm and pollinator-friendly blooms. Its key benefit is providing weeks of continuous, vibrant purple color with minimal maintenance, especially in prairie-style or informal borders. A minor caveat is its preference for well-drained soil, as it dislikes overly damp conditions. This salvia forms low mounds of textured foliage and sends up tall, reddish stems with rich purple flowers throughout summer, attracting bees and butterflies.

Troubleshooting
Plant is not flowering well.
Ensure the plant receives adequate sunlight. Avoid over-fertilizing, especially with nitrogen-rich feeds, as this can promote foliage growth over blooms. Check soil drainage.
Leaves are yellowing.
This can indicate overwatering or poor soil drainage. Allow the soil to dry out between waterings and ensure the planting site is not waterlogged.
Plant appears leggy or weak.
Provide more sunlight. Consider a light trim to encourage bushier growth. Ensure the plant is not overcrowded.
No signs of growth in spring.
Wait until the soil has warmed. Salvia 'Purple Rain' is a hardy perennial and may have a later start. Ensure the plant is healthy and cut back any dead foliage from the previous year.
