Bellis perennis. Bellis English Daisy seeds produce compact, versatile plants that are hardy in Zones 3-9. The pompon like flowers are fully double and can be deadheaded when they fade to prolong the flowering period. English daisy care includes keeping the soil moist. English daisies in the garden grow in full sun or part shade. Blooms of English daisy flowers may slow during the hottest summer days and return in cooler temperatures of late summer or fall. English daisy grows in nearly any type of well-drained soil and tolerates either full sunlight or partial shade. Plant seeds on well-prepared soil in late fall or early spring, then cover the seeds with about 1/8 inch of soil. Water the area lightly, using a spray nozzle to prevent washing out the seeds.
