What outdoor living space would be complete without a beautiful perennial garden? Considering that most perennials bloom for one to two weeks in the growing season, consider using some of these plants when designing your garden. These flowers will extend the flowering period of your perennial garden and enhance your backyard.
Black-Eyed Susans (Rudbeckia hirta) – An erect perennial with bright yellow daisy like flowers will bloom the entire month of July with regular deadheading. Provide full sun with average soil and they will self sow and therefore multiply quickly to create a mass of bright yellow in the garden.
Purple Coneflower (Echinacea purpurea) – Another erect perennial but with pink daisy like flowers (or white, Echinacea purpurea ‘alba’). This plant blooms a little later than Black-Eyed Susan but will continue into August. It will tolerate some shade but performs best in full sun. It is not a fast spreader like BES which to many people is more desirable.
Moonbeam Coreposis (Coreopsis verticillata ‘Moonbeam’) – A low mounding perennial covered with light yellow daisy like flowers 1” in diameter from late June through September. They require full sun and dry soil for best growth and flowering. You will need to deadhead on a regular basis for continual bloom. If you want to reduce the maintenance, simply shear the plant right below the flowers when you see a lot of seed heads and they will re-bloom in a week or two.
Yellow Corydalis (Coryadlis lutea) – A beautiful low growing perennial for shady moist sites. It has lobed foliage and yellow flowers for about 6-8 weeks in late spring with sporadic bloom in the summer and some re-bloom in the fall. It blooms heavily in May and June and then will set seeds. The plant is a short lived perennial but it also freely self sows which will provide additional new plants. Corydalis may be difficult to find but if you have shady gardens it is an excellent choice to provide yellow flowers throughout the season. If you would like some seeds, send a SASE to Fine Lawns and Gardens Attention: Bonnie – Corydalis Seeds.
Bethlehem Sage or Lungwort (Pulmonaria saccharata) – A clump forming perennial with spotted foliage and flowers for 4-6 weeks in spring. Blooms start out pink then turn to blue or purple. Give it afternoon shade and average soil conditions. If it gets afternoon sun the foliage will burn or wilt.
