Plumbago plants, also known as plumbago auriculata or cape leadwort, grow well in warm climates. They are a great addition to a garden, as they attract butterflies and are ignored by deer. Plumbagos are bushy plants that can grow 3-10 feet high and just as wide, according to Gardening Central.
Plumbago is an extremely reliable, resilient plant which has been popular for home gardens as well as for commercial landscapes for many years. Plumbago may be found in gardens all over the world, and was apparently popular as a standard plant in Europe. In nature plumbago is a scrambling shrub, about 3m x 3m. It grows in scrub and thicket (valley bushveld). The new growth is bright green, darker when mature.
