Amaryllis is a bulbous plant, with each bulb being 5–10 cm (2.0–3.9 in) in diameter. It has several strap-shaped, hysteranthous, green leaves with midrib, 30–50 cm (12–20 in) long and 2–3 cm (0.79–1.18 in) broad, arranged in two rows.
Place the pot in a location that receives bright, indirect light. Water sparingly until you see about 2" of new growth. From then on, water regularly. As the plant grows, turn the pot periodically to encourage the flower stalks to grow straight.
The stored bulb contains all the "food" your amaryllis needs to sprout and bloom. If you decide to keep your amaryllis for reblooming next year, you'll need to fertilize it like you would any houseplant
Prune the flowers and stalk once it’s spent and before the amaryllis develops a seedpod, which depletes the amaryllis bulb’s energy. Wait until the flowers completely fade and the flower stalk yellows before trimming it off the plant. Trim it off about an inch above the bulb, being sure not to cut into the foliage. For foliage pruning, wait until it has completely yellowed and becomes brown before trimming it off the plant.
The ideal temperature is 68 to 70 degrees F. Water sparingly until the stem appears, then, as the bud and leaves appear, gradually water more. At this point, the stem will grow rapidly and flowers will develop after it has reached full growth.
The plant is considered poisonous to humans if ingested, primarily causing stomach upset if the bulb is ingested. The American Society for the Prevention of Cruelty to Animals also lists amaryllis as being toxic to both cats and dogs. Amaryllis is also known as "naked lady" because it produces flowers before leaves on the "naked", leafless flowering stalks. Fruit of amaryllis is capsule filled with large, heavy seed. Amaryllis propagates via bulbs and seed. Plant starts to bloom 6 year after sowing.
