The little known Natal Mahogany plant, Trichila dregeana, is an excellent upright exotic looking houseplant that loves to be watered. The Natal Mahogany, a hardy, woody, bushy plant with dark green shiny leaves, can reach over 7′ in height and over 4′ in width. Although a Natal Mahogany resembles a Schefflera Amate, it’s more exotic looking and much more forgiving. Interiorscapers have learned that a Natal Mahogany can grow even in moderate, low light as long as it has enough water. These plants are considered poisonous and should be kept away from pets and children.

This plant, relatively new to the market, is an absolutely sensational indoor plant from South Africa. It’s perfect for people who tend to over-water.
A Natal Mahogany does very well in self-watering and sub irrigation pots. This should solve the watering problem. If you don’t want to invest in new pots, be sure to always leave your Natal Mahogany plant in a deep saucer filled with water while you’re away. You could also use DriWater to keep it moist.
In theory, yes you can find a natal Mahogany in a small pot. In reality, I haven’t seen one in a pot smaller than 10” in diameter and about 12” in height. They are usually sold as floor plants 4ft.-6ft. in height.
It sounds like your Natal Mahogany could use more light. Cut back the leggy growth, move the plant to a brighter spot in your home, and it should become bushier in no time.
