A dryad is a tree nymph or tree spirit who are often tied to the very tree they spring from thus if the tree dies the dryad does as well. However, for the purpose of this list, I am counting heroes and heroines who are botanically based or have botanical powers. 

Fun! We need more dryads! 

My lists are never in any particular order.

6. The Dryads' Tower by Judy Mays

or twenty long years, no druid has inhabited the tower in the dryad's valley, leaving them vulnerable to humans who'd cut down their trees. Finally, though, a mage who can protect their sacred grove has arrived seeking the magical knowledge the tower contains.

Navaar isn't a druid but they've waited long enough. No children have been born to them in too long because a dryad's tree consort, after all, cannot sire her children. A human male is needed for that. The mage Navaar is perfect, for the night they captured and seduced him, three of the dryads became pregnant. Yes, Navaar is a worthy successor to the druid who left them so long ago.

But then Navaar rescues a druidess from a Blood mage who'd wanted the tower for himself. Dylana, daughter of the druid who'd last inhabited the tower and a dryad mother, has returned to the place of her birth; and she wants the tower for herself, and no man, even if he is a powerful -- and enticing -- sex mage, is going to keep her from claiming it.
