The Paradisea plant genus includes two members: Paradisea liliastrum and Paradisea lusitanica; these go by the common names of Paradise Lily or St. Bruno's lily.
Paradisea is an hardy perennial that reaches about 24 to 32 inches (60 to 80 cm) in height, with the Portuguese and Spanish native P. lusitanica being slightly higher at 32 to 40 inches (80 to 100 cm).
It is an alpine meadow plant that carries white funnel shaped flowers that bloom towards the end of spring.

Paradise Lilies can be grown either from seed or from roots. If growing from roots then bury them about 8cm 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.
It is necessary to mulch Paradise lilies in the autumn and to feed them in the spring with fertiliser. They like a moist soil so regular watering is recommended if growing Paradise Lilies. If you require more plants then Paradisea can be propagated by division in the springtime.
