Cascalote is one of the few trees that blooms in the Winter, and when it does it a spectacular sight! This rare thorn-less version from Mountain States is known as Smoothie®. It produces large spikes of clear yellow flowers at the branch tips during the winter months, followed by attractive copper-colored seedpods. Like its parent, Smoothie® may suffer frost damage when temperatures drop below 20°F when younger. In warmer winters it will remain evergreen, with glossy green compound leaves. Smoothie ® grows best in full sun and well-drained soil.
