Plumgrannies are a melon. Imagine if you will, a little melon that fits in the palm of your hand. It's striped like a watermelon and colored much the same until it ripens. Looks like a baby watermelon covered in little stinging hairs.

When it ripens, the rind turns a rich orange color. It's incredibly aromatic. A lot of people grow them for the scent alone, rather than to eat.

Inside looks more like a cantaloupe than a watermelon. Texture and consistency, seeds, and all that.

There's lots of images from seed catalog pics on Google images. Take a look.

There are a few different varieties. I don't remember the name of the one my grandmother had. She only free it a few years, as a hobby plant. She got the seeds from someone she and Papa met camping. Anyway, as I recall it had a sharp taste to it, kind of a weird cross between a cucumber and a honeydew melon. It's unexpected, but not horrible. Mostly I remember the smell. It's the smell of late summer, early fall.
