Mimosa aculeaticarpa is a straggling, thicket forming shrub, usually growing up to 3.3 feet (1 m) tall, but occasionally double that height. The twigs are hairy and armed with backward pointing spines that easily catch in clothing. The alternate leaves are bi-pinnate with a varying number of small oblong leaflets. The flowers are white or pale pink, bunched together in globular heads. The fruits are flat pods up to 1.6 inches (4 cm) long, flattened between the seeds and splitting open when ripe.
USDA hardiness zone 3a to 10a: from −40 °F (−40 °C) to 35 °F (+1.7 °C).
How to Grow and Care
Mimosa is capable of growing in some really hardy zones and can survive in temperatures as low as -10 degrees Fahrenheit (-23 degrees Celsius). Although it grows exceptionally well in bright and full sunlight, it can grow in partially shaded areas as well. The plant can grow on a large variety of soil types like clay, loam, and sandy soil. The soil should ideally be acidic but a mild alkaline soil would suffice too. The plant is known to survive in droughts and hence requires little watering.
The ideal time for planting a Mimosa is during the spring on a well drained soil. As these flowering plants prefer soil which is acidic in nature, it is advised that you add peat moss and composted leaves at regular intervals to maintain its acidic properties. Water the plant and soil enough, but not so much as to saturate it. Keep the area under the tree clean, by sweeping away the fallen flowers and seed pods. Pruning of the branches should ideally be done during fall. This tree often tends to get infested by pests like webworm caterpillars. If affected, the branches should be removed as soon as possible to prevent any collateral damage to the plant. If not taken care of, the need to spray insecticides might arise… – See more at: How to Grow and Care for Mimosa
