Ti plants grow well in Hawaii, so well that they can get out of hand. If they look like doing so, the prudent thing is to prune, but that has one drawback. Where you cut a stem of a ti plant, two new shoots will form. This means that trimming a ti plant is a temporary fix prior to it coming back stronger.
Despite this drawback, I like them quite a bit. The lines of the leaves make for interesting patterns and shapes, especially when the sun shines on them, or through them. They’re also popular with wildlife. Geckos and anoles spend a good deal of time sunning themselves on ti leaves, or resting on the edges with one eye peering over to see what else is around. In this photo, a green anole was doing just that, but found nothing worthwhile, just me pointing my camera at him.
