Euphorbia Grandicornis Cow Horn Cactus (euphorbiaceae)

Spiky and Spiny Triangular stems are edged with rather sharp dark gray double spikes all down the entire length creating an ominous appearance. Once a year the margins explode in beautiful bright yellow flowers. When full size Grandicornis can reach 6 feet in overall height and spread up to 6 feet. The sunny spot in the yard or on the urban patio will become home for Cow Horn. Plant in multiples in close proximity they make an impenetrable smaller hedge or border.
