Alstroemeria x hybrida
Light: Gentle morning sun with afternoon shade; bright filtered shade during summer. Avoid intense western exposure and reflected heat.
Water: Keep soil evenly moist but never soggy during active growth. Check containers frequently in hot weather; reduce watering substantially when dormant without letting the root mass become completely dry.
Soil: Loose, organically enriched, very well-drained soil. Raised beds or containers are preferable to poorly draining desert soil; mulch to moderate root temperatures.
Mature size: Approximately 12–18 inches tall and 12–24 inches wide; size varies with growing conditions.
Bloom: Primarily spring and fall in Phoenix; flowering may continue during mild winter weather. Extreme summer heat commonly stops flowering.
Evergreen / deciduous: Herbaceous perennial; may remain leafy in mild weather but can become dormant during extreme heat or after frost.
Growth rate: Moderate during cool weather; slows or stops in extreme heat.
