It's right on my patio in this big clay pot. It's so lush and healthy. This plant was from a stalk I trimmed of its leaves for my sinigang. I dug a small hole and pushed the stalk in this pot. There used to be a ficus benjamina plant here, apparently I over watered it and it went kaput. The ficus trunk is still intact right there, but it's now dry, lifeless. I have used this pot since, to put all my veggie trimmings, kind of a compost bin. It is now my kangkong pot. I'll see how much it will grow, if I will have enough for another sinigang. Har har har.
One thing good about this plant, it loves water. In fact, it thrives well on swamps, ponds, and any watery place. So, there is no fear of having it over watered. Perfect for me who kills my plants with love by over watering them.
