Ti plants come in reds, greens, pink, and even striped. The green ones are the most common, and I would guess the easiest to grow.

I just hack off a piece and stick it in the ground, and it grows! Paradise!

I have been growing ti for 25 years. The red and green have intermingled over the years, and I also purchased special varieties, which have mingled with the original ones, and I save the seed and plant them. Now I have some really unusual and subtly beautiful varieties, which are as yet unnamed.

Ti plants are fun to grow from seed you save, watching them grow and change in appearance. A plant may look very different grown in sun or shade. Some plants get brighter colors in sun, some in shade, very individual. At first, they all look the same...green. Just slight differences in color of stems. The older they get, the more color they show. Also, reveal different habits, the way they display and arrange their leaves around the stalk. Width of leaves is another interesting variable, as is the sheen of the leaves.

There are many named varieties, one of the prettiest and best growing is 'Miss Andrea', small, bushy, quick to make keikis.
