Slimy. A taste I don't particularly love. But, healthy to eat. Very pretty as a vine, especially the red-stemmed variety, with green leaves and dark purple berries and delicate pink/white flowers. And very easy to grow, provided you have decent soil and a fair amount of water. And, it constantly reseeds itself.
In the rainy season, the ones I grow from potting soil grow like weeds here. But, I was hoping that quality would transfer to seeds I sowed into the local soil, and that is not at all the case - they are so far sickly, and grow extremely slowly. And as soon as they put out leaves, the damn iguanas eat them, unless I keep them netted all the time. I have a few starting even now in the pots, in the dry season, but they grow slowly and look anemic until they start getting daily water.
I would prefer a less slimy spinach, with a lighter flavor. But, they are good for you, and grow freely half the year, and I enjoy them in small quantities mixed in salad, or like in a wrap or something.
