I really don't like carnations or tulips. I love roses, orchids and calla lilies. Oh, and daffodils.

Lily of the valley, of course :D (I genuinely loved them long before joining AEPhi)
Roses - all colors, particularly those with scent
Violets, especially white violets
African violets
Hydrangea
Crocus - because it is one of the first flowers to bloom in spring
Orchids - but I don't get enough sun to grow them :(
Gardenias
Dogwood
Cherry blossoms
Azaleas

oh, I could go on and on :)
