Establishment
4-6 weeksYoung plants form basal rosette of fine, grass-like leaves emerging from substrate
Maintain stable water conditions and avoid disturbance. Ensure acidic, low-nutrient substrate. Monitor for algae competition.
Vegetative Growth
8-12 weeksLeaf rosette expands, forming dense, upright clumps of thin, linear foliage
Maintain consistent water level and temperature (65-75°F optimal). Ensure excellent light. Thin overcrowded plants if necessary.
Inflorescence Development
3-4 weeksThin flowering stems (scapes) begin to emerge from the center of the rosette, rising above the leaves
Increase light intensity to maximum levels. Maintain stable water conditions. Ensure adequate water circulation without direct current.
Flowering
4-6 weeksDistinctive ten-angled white or pale flower heads appear on multiple thin stems, each head only 1/4 inch across
Maintain peak light and stable conditions. Avoid water disturbance near flower stems. Monitor for fungal issues.
Seed Production and Decline
3-4 weeksFlower heads dry and produce minute seeds; parent plant may begin to decline
Allow flowers to mature and dry for seed collection if desired. Plant may be short-lived; plan for propagation from seed or new plantlets.
