Your squash is still immature, but a winter squash type looks right. When it gets its full mature color and size, it will be easier to know what it is/crossed with - crosses are always possible if this was a "volunteer" plant. And unless your neighbor is into heirloom veggies, I would think the varieties that are commonly available on your grocer's shelves are the usually the best guesses. FataMorgana

I think that it really depends on how we grow our plants. In nature these Hoyas go through a period of hot and dry weather which is why they have developed their succulent traits. Most growers are not going to grow their plants this way an the plants won't complain although their growth habit will certainly reflect the pampered life they receive. I would also assume that the plant in question was grown in very high light because of the closely set leaves. The red margins of the leaves make me wonder if this is not in fact Hoya subquintuplinervis? Xuan do you still have that photo of your Hoya pachyclada growing outside on the old tree stump? If I remember correctly that plant had an upright growth habit. Mike

Red malabar spinach isn't a delicate vine. The stems get quite thick as do the leaves. The stems are a dark red, almost purple and the foliage has red veins. The ripe berries are a very dark purple. There's a green version called white malabar spinach which looks the same except the stems and foliage are green and the ripe berries are a whitish green. Both can get huge!

Birds would peck - most likely leaving 'holes' in the leaves. If chewed on, could be squirrels, or chipmunks. They can climb anywhere!
