An annual widely grown as an ornamental vine. It was developed in cultivation as a hybrid between I. coccinea L. (red morning-glory) and I. quamoclit L. (cardinal climber or cypress vine). The latter has narrowly pinnatisect leaves (suggesting those of Myriophyllum), while I. coccinea has entire to dentate leaves; both are natives of tropical America and, like the hybrid, sometimes escape cultivation as short-lived adventives in colder climates. Ipomoea ×multifida was collected on newly bulldozed gravel in Jackson Co. in 1957 (C. & B.Horne 4, MICH); it or its parents may be expected to appear briefly elsewhere in the state.
