Primula in Zone 8a & 8b
Primula vulgaris
When to plant primula in zone 8b
Zones 8a and 8b share the same average frost dates in our data, so this page covers both.
Method: Start indoors: Start indoors from seed, then transplant outside. Primula needs a head start most zones can't give it by direct-sowing alone.
| Start indoors | Jan 14–Jan 21 |
|---|---|
| Direct sow / transplant outside | Mar 11–Mar 18 |
| Estimated bloom | Mar 10 '28–Mar 17 '28 (First real harvest the season after planting) |
Spacing: 2 per square foot (square-foot-gardening spacing). Mature height: 0.5-1 ft.
Primula is one of the earliest things in the garden, often flowering before the last frost has passed.
How primula fits zone 8's season
Zone 8b's frost-free window runs about 230 days, from March 25 to November 10. Primula takes about 1 growing season to reach full flowering, so what matters here is how many of these seasons it gets, not whether one is long enough.
Primula is hardy in zones 4-8, so in zone 8b it stays in the ground through winter and comes back rather than being replanted. Allow about 0.75 ft of spread at maturity.
