Ice Plant (Delosperma) Identification and Flowering Tips

Succulent with yellow daisy-like flowers grown ~1 year. Asks for ID, flowering tips, if overcrowding prevents blooms.

Identification: Ice Plant (Delosperma spp.)

• Yellow-flowered = likely Delosperma nubigenum or D. congestum
• Mat-forming succulent, zone 5-9 hardy
• Flowers summer (June-August in NH)

Flowering Strategies

1. Hanging basket: Better drainage, cooler roots, more flowers
2. Full sun: 6+ hours direct
3. Lean soil: Sandy, gravelly, low organic matter
4. Dry winter: Rest period improves bloom
5. "Super Bloom" fertilizer: High P, low N (optional)
6. Apple trick: Cut apple nearby—ethylene may trigger bloom (works for bromeliads, some succulents)

Equatorial Note

Near equator, seasonal cues absent. May need artificial "winter" (cool, dry) to induce flowering cycle.

Overcrowding

Not typical bloom inhibitor for ice plant—they flower prolifically in mats. But container restriction + rich soil = vegetative growth over flowers.
