Lifecycle	annual
Edible parts	leaves, stems

Growth Stages

Stage	BBCH	Notes
Sowing and germination	0	Direct-sow fresh seed about 0.5cm deep in full sun, well after the last frost once soil is reliably warm; germinates in 7-10 days (Johnny's Selected Seeds).
Thinning and establishment	1	Thin seedlings to 10-15cm apart; water regularly until well established, in lean, well-drained soil (Johnny's Selected Seeds).
Succulent leafy growth	3	Becomes notably drought-tolerant once established, needing only deep, infrequent watering; loves baking full sun and lean soil (Johnny's Selected Seeds).
Continuous harvest	8	Harvest young, tender stems and leaves continuously from about 4-6 weeks after germination, through to 40-60 days maturity; monthly successional sowing keeps up supply (Johnny's Selected Seeds).

What the research guides add

Purslane is a garden weed and a salad plant at once, and NC State describes its toughness.

• An annual succulent that is drought-tolerant once established and grows in full sun and well-drained soil; propagation is by seed and stem cuttings. (NC State Extension)
• Its taproot and fibrous secondary roots tolerate poor, compacted soils and drought. (NC State Extension)
• The flowers are small, yellow and open only briefly in the morning, each replaced by a seed capsule that splits to release dark seeds. (NC State Extension)
