Growing Salvia in Zone 4B

Salvia is a diverse genus with hundreds of species — all attractive to hummingbirds and butterflies, and most extremely heat and drought tolerant.

Zone 4B has a short growing season — start seeds indoors when possible and use season-extending techniques like cold frames and row covers.

Top Growing Tips

• Annual salvias (S. splendens) need 10-12 weeks from seed
• Perennial salvias (May Night, East Friesland) return yearly in zones 4+
• Cut back by half after first bloom flush to encourage repeat flowering
• Blue and purple salvias are especially attractive to hummingbirds
• Very deer and rabbit resistant — aromatic foliage deters browsing
