Establishment
4-8 weeksNewly planted rosette with narrow, strappy foliage emerging; plant develops root system over first 1-2 months
Water moderately to establish roots; ensure excellent drainage. Avoid overwatering. Plant in spring for best results.
Vegetative Growth
1-2 years (until flowering age)Plant develops dense clump of blue-green, sword-like leaves growing 12-24 inches tall; no flowers yet
Minimal watering required; drought-tolerant once established. Apply light mulch around base if in cooler zones. Remove dead or damaged leaves.
Flowering
3-4 months (or longer in warm regions)Striking flower spikes emerge from center of rosette, reaching 3-5+ feet tall, lined with small tubular red, coral, or pink flowers opening progressively from bottom to top
Blooms typically appear late spring through fall (may extend year-round in warm climates). Deadhead spent flowers to encourage continued blooming. No fertilizer needed.
Seed Production
4-8 weeksFlowers fade and develop seed pods; flower spike becomes woody and brown
Allow some spikes to mature for seed production if desired for propagation. Remove spent spikes at any time to tidy appearance or encourage re-blooming.
Winter Dormancy
2-3 months (zones 8-9)In cooler zones, growth slows significantly; foliage may develop reddish tones in cold weather. In warmer zones, plant continues growth
Withhold water nearly completely in zones 8-9. Provide frost cloth or cactus blanket protection in zone 8 if severe freezes occur. No pruning needed.
