The Lilium genus are grown as half hardy or hardy bulbs in the garden.
Due to the large size of the genus, there is a large range in height (from 30 to 1.8 m; 1 to 6 feet) in the lily (Liliaceae) family.
Lilies usually have lance shaped leaves, long upright stems, and beautiful trumpet shaped fragrant flowers.
Depending on the species, Lily bloom from the end of spring through to the end of summer.

The lily can be grown from either seeds or lily bulbs. It is probably easiest to grow from bulbs. As the Lilium genus is large the variation in lily bulb size is large too. Smaller species should be burried about 6 cm deep, whereas larger ones needed to be planted ad deep as 30 cm (1 foot).
The best way to decide how deep to bury a lily bulb is to multiply the size of the bulb diameter by three, and bury it that deep. Bulbs can be planted out in either autumn or at the start of spring.
The bulbs of small lilies should be spaced about 25 cm (10 inches) apart, whilst bigger lily varieties should be spaced about 50 cm (20 inches) apart. If you prefer to grow lilies from seed, then they should be sown at about 6 mm deep before the last frost of spring, or in autumn.
It can take from two to four years before seed grown lilies will flower.
Lilies can be grown in both sunny and lightly shaded conditions, this depend on the species. As a generalization lilies like to grow in a slightly acidic moist soil.
Lilies take a little caring for: they require regular watering to keep the soil moist during their most active growing periods. The lilies base should be mulched in the spring. Lilies require to be fertilized at the start of spring and when the flowering period has finished. dead flowers should be removed. Lily stems should be cut back to the ground level upon the first frost of the winter.
The Lilium plant will produce bulbils or bulb scales, so if you require more lilies in the garden then these can be used for propagation at the beginning of autumn.
