Growing White Sage: A Complete Profile
By Growing Home Greens Team · August 10, 2026
White sage is a different species from the common culinary sage already covered on this site, grown mainly for its silvery, fragrant foliage, traditionally dried into smudge bundles rather than used in the kitchen.
Sowing
Transplant, sowing 2 to 3 seeds a quarter inch deep into individual containers 8 weeks before the last frost, thinning to one plant per cell after germination. Direct-seeding in spring, as soon as the soil can be worked, also works, sown a quarter inch deep. Germination takes 7 to 14 days at 65-70°F. Space plants 12 to 18 inches apart in rows 18 inches apart.
Less cold-hardy than common sage
White sage is hardy in zones 6-9, noticeably less cold-tolerant than common culinary sage. In areas where temperatures regularly drop below 10°F, mulch heavily in late fall or dig up, pot, and bring the plant indoors to overwinter rather than leaving it exposed.
Harvest
Individual leaves or branches can be picked the first year once plants are established. In the second year and beyond, cut stems to within 6 inches of the base just as flowers begin opening, then hang small bunches upside down to dry in a well-ventilated spot out of direct sunlight. Once established, it also propagates readily from softwood cuttings taken in spring or early summer.
White sage has no well-established companion pairings, and nothing it needs to be kept away from. At 1 plant per square foot, it’s a fragrant, silver-foliage addition to the Garden Designer, best given winter protection outside its zone 6-9 comfort range.

Varieties worth considering
- Straight-species white sage (Salvia apiana): Johnny's Selected Seeds sells this species plain, without competing named cultivars; the silvery foliage and fragrance are traits of the species itself, distinct from the culinary sage cultivars sold nearby. (source)
Why each variety is listed comes from the source shown next to it. We haven't grown these ourselves yet, so treat this as a research-backed starting point, not a personal endorsement. The buy links are separate from those sources: they go to seed suppliers that sell that exact variety, and we may earn a commission on some of them.
Where to buy white sage seeds
None of the seed suppliers we list carries white sage seeds right now. A local garden center or a specialty seed house is the place to look.
