Hippeastrum reginae, commonly sold as an amaryllis, is a bulbous geophyte native to tropical South America. It produces a thick, hollow flower stalk (scape) bearing several large, trumpet-shaped blooms—typically vivid scarlet to orange-red with a green throat—followed by or accompanied by strap-like, arching leaves. The bulb stores energy to power a dramatic flowering display each season. Unlike true Amaryllis (Amaryllis belladonna from South Africa), Hippeastrum reginae grows and flowers indoors reliably when given bright light, a snug pot, and excellent drainage. After flowering, the plant channels energy back into the bulb; maintaining healthy leaves for weeks to months is essential to support next year’s bloom. A brief dry rest period mimics its native seasonal cycle and helps reset the bulb. Grow in a fast-draining, gritty mix with one-third of the bulb exposed above the medium. Rotate for even growth, stake if needed, and protect from cold drafts. With proper light, careful watering, and a sensible feed-rest rhythm, it rewards with spectacular, long-lasting blooms.

How to care for Queen Amaryllis
Water
At planting or when growth resumes, water thoroughly until excess drains, then wait until the top 3–5 cm (1–2 in) of mix is dry before watering again. Bulbs dislike waterlogged media; never leave the pot standing in a saucer of water. Reduce frequency once flowering ends, but keep the leaves slightly moist as they recharge the bulb. For dormancy, provide only a light sip every 3–4 weeks to prevent complete desiccation, resuming regular watering when new growth appears.
Light
Provide bright light with several hours of direct sun. Indoors, a south- or east-facing window is ideal; supplement with grow lights if daylight is weak. Outdoors (frost-free seasons), give morning sun and afternoon shade to avoid scorching. Insufficient light leads to weak, elongated scapes and fewer blooms; too much harsh midday sun can burn leaves. Aim for 4–6+ hours of strong light daily.
Nutrients
Feed regularly only while in active leaf. Apply a balanced, low-salt liquid fertilizer (e.g., 10-10-10 or 5-10-10) at half strength every 2–3 weeks from leaf emergence through 6–8 weeks after flowering to rebuild the bulb. As buds form, shift toward a higher-potassium ratio to support blooms. Flush the pot with plain water monthly to prevent salt buildup. Do not fertilize during the dry rest or when soil is kept nearly dry.
Temperature
Best growth occurs at 18–24°C (65–75°F) with cooler nights around 13–18°C (55–65°F). Protect from frost; prolonged exposure below 5°C (41°F) can damage bulbs. During a rest period, keep bulbs cool and dry at 10–15°C (50–59°F). Very high heat (>30°C/86°F) with low light can weaken scapes and reduce flower quality, so provide good light and ventilation in warm weather.
