English Bellis Bellis perennis. Bellis English Daisy seeds produce compact, versatile plants that are hardy to Zone 3. The pompon like flowers can be deadheaded when they fade to prolong the flowering period. Plants stay very compact at only 15-20cm (6-8"), so they are great for tucking into containers or any little empty spot near the front of flower beds. This is a great option for adding low-growing flowers into lawn settings, but the seeds should be started in plugs - not just scattered over established lawns.
