Germination & Seedling
2-3 weeksSeeds sprout and develop first true leaves within 10-14 days. Seedlings are delicate with oval cotyledons followed by small, narrow leaves.
Keep soil moist but not soggy. Provide bright light. Thin seedlings to proper spacing once they have 2-3 true leaves. Keep temperature around 60-70°F.
Vegetative Growth
3-4 weeksPlant develops rosette of increasingly larger leaves. Foliage becomes lush and dense. Leaves deepen in color and become more tender.
Water consistently. Apply balanced fertilizer every 3-4 weeks. Remove any flowering stalks immediately to encourage leaf production. Thin to final spacing.
Leaf Harvest Ready
4-8 weeks (ongoing harvest)Outer leaves reach 4-6 inches long and become tender enough for harvesting. Plant continues producing new leaves from center.
Begin harvesting outer leaves regularly. This encourages continued production and prevents flowering. Pinch off any flower buds that appear.
Flowering (if allowed)
2-3 weeksIf not harvested and left to mature, plant sends up flower stalks with small greenish flowers in spikes.
Remove flower stalks promptly if leaf production is desired. Allow flowering only if seed collection is intended.
Seed Production
3-4 weeksFlowers develop into small winged seed pods. Seeds mature and dry on the plant.
Allow flowers to go to seed only if saving seed is the goal. Collect seed pods when they turn brown and papery.

Harvest Tips
Begin harvesting outer leaves once they reach 4-6 inches long, typically 45-50 days after planting. Harvest in the morning when leaves are crisp and full of moisture. Pinch or cut leaves from the outside of the rosette, working inward, allowing the center to continue growing. Never harvest more than one-third of the plant at once. Regular harvesting encourages more tender leaf production and prevents early flowering. Leaves are most tender when young; older leaves become tougher and more bitter.
Fun Facts
- 🌱 Pūpae is a native or naturalized species of New Zealand and has been part of Māori dietary practices for centuries before European contact.
- 🌱 The name 'pūpae' comes from te reo Māori (the Māori language) and refers specifically to this nutrient-rich edible green.
