I could repeat the name but then that would be parroting.

I think this is erythrina abyssinica. The leaves look very similar to your picture.

Also commonly referred to as Wax Begonias. The amount of ground each individual plant covers is dependent on how each individual plant grows for you. I've seen estimates of everything from 4 to 10 inches. With too much sun, the leaves can turn translucent and pretty ugly. Partial sun suits them fine and they don't mind being close together. I'm going to play Ken here and say your posts often leave out details that could be useful - are you wanting to cover a big space as in the Old Victorian practice of carpet bedding? A patch here and there? Or a border? How much space - as in footage - are you wanting to devote to this plant? Coverage might be trial and error as to the number of market packs you'd need. It's such a popular plant, Home Depot, Wal-mart, etc. carry racks and racks of them every year so not starting out with enough first time around is easy to remedy.

It's either passiflora vitifolia or coccinea. The flowers are pretty similar--the easiest way to tell them apart is by the numbe of lobes on the leaves. Vitifolia, the grape leaf passionflower, has three lobed leaves, and coccinea has entire leaves (one lobe).
