I'm with most of the others - liking different things at different times of the year.
Am rather fond of the first of each genus - the 1st snowdrop, early daffs, tulips, hyacinths etc because they herald spring & lengthening/warmer days, when all the foliage seems fresh & new.
I also love blossom-time on apples, pears, prunus.
Then I keep buying lilies for their gloriously large flowers & knockout scent, even though I have to keep them in pots & hunt/destroy lily-beetles every day!
And finally, like Dahlia lover, I enjoy growing Dahlias from seed. They don't seem to need too much help & it's always a late-colour surprise because for some reason I can only find mixed-colour packets.
