For cultivation in gardens, we recommend white (Lilium candidum), royal (L. regale) and tiger (L. tigrinum) lilies. Garden lilies grow best in humus, fertile, deeply cultivated soils, in sunny places, but shaded for several hours a day. The bulbs of white and royal lilies are planted in mid-August to a depth of about 15 cm at intervals of 30-35 cm, while the bulbs of tiger lilies are planted in September at a depth equal to their three times their height, at intervals of 30-40 cm.Lilies can grow in one place for 3 yearsIn the garden they look decorative when planted in large groups against the background of lawn or coniferous shrubs.
