This tree’s common name, the ironwood, comes from the dark, heavy wood it produces, which sinks in water. It actually ranks as the 8th densest wood on earth at 75.4 lbs. per cubic foot. Well adapted to the desert heat and arid climate, the number one cause of death for this tree in a landscape is overwatering. This tree’s natural form is multi-trunked, 20-40 feet in height, and equally as wide. With soft grey green leaves and purple pea shaped flowers, this tree seems almost too graceful to thrive in the harsh desert; however, its short, hard thorns are a reminder that it truly is a desert native . 47 Ironwoods are scattered across campus; be sure to keep an eye out for this fascinating tree!
