Any where you see a sea grape, you will see a gazillion seedlings. I have 2 sea grapes and believe me, I would not purposely plant them. Mine are old trees from when the house was built.

The grapes are messy, they stink, it's a pain in the butt to walk through them, the iguanas love them and crap the seeds everywhere, the seedlings pop up everywhere.....

How about from cuttings? Will they produce the grapes it I have two cuttings, from the same tree, of will I need each from a different plant, genetically?

Why bother with cuttings? The seeds will germinate faster than cuttings will form roots. And no, you don't need two different plants to get grapes. By the way, the grapes are edible. Although, they taste just this side of styrofoam.

How long does it take to mature, if you grow them from seeds?

Mature to what? A 20' tree or a seedling? I've seen them grow several feet in a year, but that depends on their environment.

Mature to growing edible, normal sized, fruit.

For most of us, edible will never happen. However, they will usually start producing grapes anywhere from 2 to 3 years from seedlings.

I love my seagrapes! & yes! I agree seeds are the easiest way to propagate them.Look for seedlings & carefully dig them up & pot them.

The fruit is VERY yummy, tho very thin-fleshed - & problematically, the fruits fall off when fully ripe(dark, plump & soft)
& they ripen individually, so it's difficult to harvest any significant number @ 1 time = (

However, I've been grazing on mine lately (what I can reach)
& I probly look like a nutcase to passersby = J

& those pesky fallen fruits don't sprout very much if you let the fallen leaves remain in place.

Sea grapes make wonderful jelly and jam. I don't much like them right off the bush either.

They will probably take about 2-3 years to have fruit when grown from a cutting of a mature plant. Hope that answers your questions.

This is a gravel area around my tool shed. Of course, you can't see much of the gravel because of the sea grapes....
