|My grandfather just bought a home with very little landscaping and since this has become a new passion of mine in recent years, I've decided to landscape his yard for him in my spare time. I'm mainly focusing on plants and flowers that will come back year after year, including annuals that reseed themselves, to keep maintenance and replanting to a minimum. Do annual salvias, scarlet sage in particular, reseed themselves or do they require replanting next spring?|
|Salvia is not a reliable self-sower. The seeds are fragile and short-lived so you'd have best results if you purchased new seed each year. Annuals that freely self-sow include sweet alyssum (Lobularia maritima) and pot marigolds (Calendula officinalis).
Self-sowing perennials include purple coneflowers (Echinacea purpurea), Virginia spiderworts (Tradescantia virginiana), gloriosa daisies (Rudbeckia hirta), and garden phlox (Phlox paniculata).
Good luck with your new landscaping project!
