One of my best lily is the calla lily. It is far an away the best Lily. My daughter might disagree as she loves growing Lily's.
Cali lily's don't fare well here in Western Pennsylvania as you have to bring them in to protect them from the hard freezes we get here.
Morning glory is another of my favorites as it is a perennial,meaning it grows from year to year. It climbs so you can do as some people do and plant it around your mailbox or the porch.
Another one is the tulip and it is also a perennial. You see them selling just before Easter as the Lily is also seen at roadside stands plus more flowers they sell.
