About Lilium 'Black Beauty'

Lilium 'Black Beauty' · also called Black Beauty lily, dark red Oriental hybrid lily · flowering

'Black Beauty' is a vigorous Orienpet (Oriental x Trumpet) lily with masses of deep crimson-black, white-edged recurved flowers and a light fragrance in mid to late summer. Exceptionally robust and long-lived, it tolerates a wide soil pH, reaches well over head height in good conditions, and bears dozens of blooms. Like all lilies, it is acutely toxic to cats.

Mature size: 150-200cm tall and 30-40cm wide; can carry 20-50 blooms on an established stem.

Watch for — Wind rock on tall stems: At 1.5-2m the stems can sway and lean in exposed sites. Plant in a sheltered spot or provide a tall, discreet stake.

Indoor size vs how big it gets in the wild

Lilium 'Black Beauty' grows into a room-scaled plant of roughly 150-200cm tall and 30-40cm wide — bigger than a tabletop plant, but not a tree. Indoors and in a pot, expect 150-200cm tall and 30-40cm wide. In the ground with no restriction it is a completely different plant — can carry 20-50 blooms on an established stem. — 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

Lilium 'Black Beauty' is a fast grower. Realistically, expect two to four years from a young plant to a room-filling specimen in good light. Its feeding profile backs this up: feed with a balanced fertiliser at emergence and a high-potassium liquid feed every 2-3 weeks from budding to support the large flower load and replenish the bulb. let foliage die down naturally.
