What Garden Flowers Could We Plant To Attract Butterflies And Bees?

Though most nectar-producing flowers attract both bees and butterflies, there are certain favorites of each.
Butterflies prefer candytuft (Iberis umbellate), cornflower (Centuaurea cyanus), forget-me-not (Myosotis), sweet scabious (Scabiosa atropurpurea), marigold (Calendula Officinalis), mignonette (reseda), which are all types that blossom the year round, whereas seasonal varieties preferred include sweet william (Dianthus barbutus-July), sweet rocket or dame's violet (Hesperis matronalis), New England aster or Michaelmas daisy (Aster novae-angliae summer autumn/summer), sedum spectabile, honesty/silver dollar plant (Lunaria annum spring/summer), achillea millefolium, dianthus deltoids and aubretia.  

For bees, try lavender, lupin, sage, rhododendron, Phacelia tanacetifolia, borage and cotoneaster, which are common garden plants. Some wild flowers that do an equally good job are viper's bugloss or Echium vulgare, comfrey or Symphytum officinalis, red clover or Trifolium pretense and greater knapweed or Centaurea scabiosa.

Butterflies like bright flowers. They see certain colours I've been told, but not sure who asked the butterfly.  I have azaleas, Cassandra, roses and gardenias in my flower bed and the butterflies are everywhere. Oh, I also have cotton growing and it makes a very pretty lilac colour flower before it turns into cotton, the butterflies like that too.
