Fritillaria pyrenaica is another species that varies in color and form a great deal. From Spain and Western France Fritillaria pyrenaica will reach 18" once bulbs are mature.
Fritillaria pyrenaica has a maroon outer petals with yellow inners. Pretty bell shaped flowers in mid spring. Originally from the Pyrennes a well drained sunny potion is best. Ours are pot grown and are a hardy bulb. Some varieties have darker bells, some with traces of the 'chequered look'.
As this is one of the earlier fritillaries to flower it is also suitable for naturalising into lawns. Simply lift a sod or two awya from areas of foot traffic, plant the bulbs and replace the loosened sod.
