Purslane in Zone 3a & 3b
Portulaca oleracea sativa
When to plant purslane in zone 3b
Zones 3a and 3b share the same average frost dates in our data, so this page covers both.
Method: Either: Start indoors for an earlier harvest, or direct-sow outside for less fuss. Purslane tolerates either.
| Start indoors | May 9–May 16 |
|---|---|
| Direct sow / transplant outside | May 30–Jun 6 |
| Estimated harvest | Jul 19–Jul 26 (~50 days after planting) |
Spacing: 4 per square foot (square-foot-gardening spacing). Mature height: 4-8 in.

Purslane has a genuine identity crisis: most gardeners spend years pulling it as a weed before realizing the same succulent, mildly citrusy leaves are a legitimate salad green, and a cultivated selection exists specifically bred for eating.
How purslane fits zone 3's season
Zone 3b's frost-free window runs about 98 days, from May 30 to September 5. Purslane needs about 50 days from sowing to first harvest.
