2nd Year Maturity. Sensitive Plant mimosas guarantee one of the most interactive, playful, and entertaining blooms you"ll ever grow. Sensitive Plant seeds grow a neat 12-24 inch tall shrubby mimosa bursting with delicate 1 inch pink "pom-pom" blooms whose leaves are known world-wide to be seisomonastic (responding to physical touch and movement). Sensitive Plant mimosa seeds are a perfect grow for adding a brush of grace to window boxes, rock gardens, hanging baskets, or keeping anywhere guests or children can touch and watch the leaves recoil right before their eyes. Sensitive Plant mimosa thrives in a diverse variety of humid gardens and its nectar-rich blooms will keep your vegetables and crops healthy and abundant with important pollinators well into the summer.
