Members of the Sprekelia plant genus are half hardy bulbs. The plants are often grown as annuals in the garden.
They range from 15 to 30 cm (6 to 12 inches) in height. Sprekelia bloom from towards the end of spring through early summer.
Sprekelia have narrow lance shaped leaves. They carry red flowers reminiscent of lilies.

If growing outdoors from the off, then grow Jacobean lilies and other Sprekelia from bulbs.
Plant the Jacobean lily bulbs at a depth of 10 to 15 cm (4 to 6 inches) a couple of weeks after the last frost of spring, or in the autumn in hotter areas.
Sprekelia plant species should be spaced about 20 to 30 cm (8 to 12 inches) apart. They can grow in sunny or partially shaded locations, that have good drainage.
Ideally the soil that Sprekelia grows in should be fertile.
If growing from seed, then start off indoors. The seeds should be lightly covered and allowed to germinate at a temperature of 18 to 22 degrees centigrade (64 to 72°F).
Grow the plants indoors for about two years, then transplant outdoors a couple of weeks after the last frost of spring.
It will take about seven years until seed grown Sprekelia plants will produce flowers.
It is fairly easy to look after Sprekelia plant species such as Jacobean lily and Aztec Lily.
They should be regularly watered, and require to be fertilized every two weeks during the growing season.
If you require more plants, then they can be propagated by planting the bulblets that they produce following flowering.
