Hedra (hed-er-ah), Ivy; Araliaceae Family. Hedra is a genus of 12 to 15 species of evergreen climbing or ground-creeping woody plants. Native to western, central and southern Europe, northwestern Africa, central-southern Asia east, Japan and Taiwan. Evergreen, Ivy provides year-round interest as border edgings or foundation groundcovers. Many ivies are fast growing and will quickly fill in bare spots. This makes ivy a good choice as groundcover under trees, where other plants refuse to grow.
In the right conditions, ivy can be a vigorous grower. Plants should be set about one to two inches deeper than the upper layer of the potting medium, for additional root development. Ivies grow best on sites where the soil is aerated and well drained. Ivy is not tolerant of extreme drought or extended wet soil conditions.
Ivies are used in window boxes, urns and other elevated planters for cascading effect, indoors or outside; as ground covers and are trained on walls, fences, posts and trellises.
