About Amaryllis 'Red Lion'

Hippeastrum 'Red Lion' · also called Red Amaryllis · flowering

'Red Lion' is the classic deep-red amaryllis, sending up a tall hollow stalk topped with two to four large velvety trumpet flowers from a single fat bulb. Easy to force indoors in winter, it wants bright light, a snug pot, sparing water until growth starts, and a dry dormancy to rebloom.

Mature size: Flower stalk reaches 45-60 cm tall with blooms up to 15-20 cm across; leaves arch to a similar length.

Watch for — Tall stalk flops over: Low light makes the heavy-headed scape stretch and lean; grow in the brightest spot, rotate the pot daily, and stake tall stems if needed.

Indoor size vs how big it gets in the wild

Indoors and in a pot, expect flower stalk reaches 45-60 cm tall with blooms up to 15-20 cm across. In the ground with no restriction it is a completely different plant — leaves arch to a similar length. — which is why the pot, the light and the pruning matter so much for the size you actually end up with.

It builds steadily in both height and spread to a medium, manageable size, filling a pot and a corner over a few years.

Growth rate and years to mature

Amaryllis 'Red Lion' is a moderate grower. Realistically, expect three to six years to reach mature indoor size, gaining a steady amount each growing season. Its feeding profile backs this up: once leaves appear, feed every 2-3 weeks with a balanced or high-potassium liquid feed through spring and summer to recharge the bulb. stop feeding when foliage yellows ahead of the dormant rest period.
