TRADESCANTIA - Spiderwort — (-20oF, USDA Zones 5-9) This is one plant that you are okay to ‘neglect’. It needs to be ‘starved’ to prevent excessive growth. This means planting in poorer soil, giving it minimal water and fertilization. However, if you live in hot, dry areas, give it more water and some light shade. If you significantly cut it back, you will not only get new growth, but it will also re-flower as weather gets cooler.

They are easy to grow, but do not like being moved much, so select a spot they can stay in for awhile. This is a great plant for a woodland setting. Give moist, humus-rich soils in a cool partially shaded location. Mulch in the fall with leaf mold. Some selections may be slower to flower.
