Astonishing in bloom! From the highlands of Guatemala and S. Mexico comes this extremely rare evergreen Sun­flower tree. In its native habitat it grows to 20’ tall, though here in the Bay Area we’ve not seen it reach more than 10’. Handsome 6” tropicalesque leaves are held on strong upright bamboo-like branching stems but the real show comes February-May when the flowers appear – 3” across, clear white with a gorgeous raised black center encircled by a lime green ring. Lightly fragrant! Fast-growing and best in cool coastal areas where temps don’t often rise much above 80 degrees F. Provide rich soil and regular water. Can be grown indoors in a container.
