How to Grow Paradise Lily

Paradise Lilies can be grown either from seed or from roots. If growing from roots then bury them about 8 cm (~3 inches) deep in either the spring or autumn.

Paradise Lilies are able to thrive in either a sunny or partially shaded part of the garden, and require good drainage. The soil should be rich and deep.

If you plan to grow Paradise Lily (Paradisea) from seeds, then sow the seeds into flats in the springtime. The flats should then be put into a plastic bag and placed in the fridge for about three weeks.

The flats should then be sank into a shady part of the garden. It may take from one to six months to germinate.

As soon as seedlings emerge, transplant them into their desired location. It will take about three years before seed grown Paradisea will flower.
