Dormancy/Tuber rest
2-3 monthsSubterranean tuber remains dormant through late summer into autumn; no visible above-ground growth.
Keep soil relatively dry. Ensure proper chilling period if species requires cold dormancy. Allow soil to warm gradually as growing season approaches.
Vegetative emergence
3-4 weeksShoots emerge in autumn to early winter; narrow, linear leaves begin to develop above ground.
Increase moisture as growth begins. Provide bright, indirect light. Maintain cool temperatures (55-65°F ideal). Ensure mycorrhizal associations are active.
Leaf and stem development
6-10 weeksPlant develops 3-8 narrow, grass-like leaves; stem elongates to support flowering structure.
Maintain consistent soil moisture without waterlogging. Continue bright, indirect light. Support with stakes if needed for taller species. Avoid disturbance to developing root system.
Flowering
2-4 weeksDistinctive orchid flowers emerge, ranging from red and pink to white, yellow, or purple, often with intricate patterns and spider-like or insect-like features.
Maintain steady moisture and cool temperatures. Provide excellent air circulation. Avoid moving plant during bud development. Do not fertilize; many Caladenia species are sensitive to high nutrients.
Seed maturation and senescence
4-8 weeksFlowers fade and seed pods develop. Above-ground foliage gradually yellows and dies back naturally.
Allow seed pods to mature fully if seed propagation desired. Gradually reduce watering as plant enters dormancy. Do not remove foliage until completely brown to maximize tuber energy storage.

Common Pests
-
and
Remove by hand in evening; use copper barriers or organic slug bait. Maintain good air circulation to reduce conditions slugs favor.
-
Increase humidity and air circulation. Spray with water to dislodge. Use neem oil if severe, though these orchids are sensitive to many sprays.
-
Remove with alcohol-dipped cotton swab. Quarantine affected plants. Use insecticidal soap cautiously on orchids.
-
Improve drainage and air circulation immediately. Remove affected tissue. Reduce watering frequency. Repot in fresh substrate if widespread.
-
Do not overwater or use conventional potting mix. Inoculate with appropriate orchid mycorrhizal fungi. Source plants from reputable native orchid specialists.
Uses
Native pollinator support

Harvest Tips
Caladenia orchids are grown for ornamental flowering; do not harvest flowers, as this stresses the plant and prevents seed formation. Allow flowers to be pollinated naturally by insects for seed development. Collect mature seed pods (when brown and papery) in late spring to early summer. Seeds should be sown immediately or stored in cool, dry conditions for up to 1 year.
Fun Facts
- 🌱 Many Caladenia species use sophisticated visual and chemical mimicry to attract specific bee species for pollination, with flowers resembling female bees or other insects.
- 🌱 Caladenia orchids form obligate relationships with specific mycorrhizal fungi; without the correct fungal partner in the soil, the plant cannot establish, absorb nutrients, or flower successfully.
- 🌱 The genus includes the remarkable species Caladenia supplans, which self-pollinates and can produce over 2 million seeds in a single seed pod—one of the highest seed counts in the plant kingdom.
