Solanum lanceolatum

Grows well in full sun to parrt shade in zone 5a/b. Can get aphids if plant doesn't get enough air space, but nothing a garden hose and a windy day can't resolve. Easy to grow from seed.

Fast growing tropical looking shrub that reseeds in the watered yard.Gets gangly and ugly if not pruned to shape.
Kennedys second picture isn't S. lanceolatum,but S. lanciniatum.

We've grown it every year for about five years. We collect the seed from the pods (fruits) and let them dry a bit. They give a nice tropical look when placed in containers or next to caster beans and cannas. They do like a lot of water and get ugly very quickly when they wilt.

I bought it at the Montreal Botanical Garden in May, was about 1 foot tall, now at the end of July it is 3 feet tall, and in full bloom, with a lot of "green" fruits. Can be propagated by cuttings of half-ripe wood at the end of August, or by collecting the seeds when the fruits turn yellow.
Not hardy enough to survive our winters, but I will do anything to save it for next spring. It is very lovely and fast growing.

This plant is also known as Kangaroo Apple. Apple because of the edible fruit. Kangaroo, because the intermediate leaf, can resemble a kangaroo's footprint, having a single leaflet on one side of the main leaf.
