Can you help me identify this plant? Is it a vine?
This plant is a Pelargonium Peltatum / Ivy-Leaved Pelargonium. It's closely related to the zonal pelargoniums. (And hence often somewhat mixed up)
Typical characteristics are
- waxy, ivy-shaped leaves
- long distances between the leaf nodes and thus
- trailing or hanging growth, suitable for window boxes, hanging baskets or similar
- often, but not always with flower clusters that apperar more sparse or "thinner" then their p. zonatum relatives.
In Central Europe (where I live), Pelargoniums are "the" plant for window boxes etc., so I've seen my share of them. Especially the ivy-leaved P.s (simply called "Hängegeranie" / hanging pelargonium here) can look spectacular.
This plant has a common name of zonal geranium or pelargonium. They are native to South Africa but are more commonly seen as outdoor bedding plants where they are treated as annuals.
To positively identify this plant there should be hairs on the underside of the leaves and the flower should be similar to this: and the leaves should be similar to this
