While I like to grow Purple Sage (lavender flowers and purple-green leaves) and Pineapple Sage (red flowers and green leaves), I have never seen seeds for these varieties. There are just a few seed ideas for sage from most seed companies.
Seed Ideas:
Broadleaf Sage – this variety has larger gray-green leaves and purple-blue flowers
Common or Garden Sage – this variety has lavender flowers
