The Crown Imperials are those we know best, though this only represents the species Imperalis, so attractive in the garden and so popular as a cut flower. This is a plant that is extremely partial to lime, in fact in the limestone areas of the East Cotswolds a dwarf species, F. meleagris, may be found growing naturally in meaciows during late April and early May. It is known to country folk as the Snake’s-head Lily. The fact that the Fritillarias bloom throughout May makes them a most valuable plant for herbaceous border or rockery, where they should be planted in clusters towards the front of the border or at the back of a rockery, whilst several of them can be naturalized to good effect. Especially are F. meleagris and F. pyrenaica delightful when planted in an orchard where the grass is not cut before the beginning of July.
SOIL AND PLANTING
The fritillarias enjoy a deeply dug soil and one containing plenty of humus, The bulbs appreciate anything which will ensure a cool, moist soil during summer Old mushroom-bedis ideal, so is hop manure and some peat. The plants must have plenty of moisture when making growth during late spring, but must have a well-drained soil otherwise the bulbs may decay during an excessively wet winter. It is advisable to plant the large bulbs on beds of sand to encourage while a mulch with rotted manure or peat after flowering will help to retain soil moisture during summer. When preparing the soil do not neglect the addition of lime rubble where this is not present in the natural form.
The bulbs should be planted 6 in. deep in September or earlier if the soil is heavy and a strongrun is required before winter.
Deep planting will prevent the bulbs from drying out during a period of drought. They should be left undisturbed for several years for they do not like undue disturbance. When it is necessary to lift and divide the clumps the small bulblets should be removed and planted into beds of peat and sand where they will in twelve months attain flowering size and be ready for their permanent quarters. This is a better method than growing fromwhich takes five years until the plants reach flowering size. If it is required to grow from seed, this should be sown as soon as ripe in pans of a pure peat and sand mixture, the being transferred to individual as soon as large enough to handle.
