Xysmalobium undulatum
"Milk Bush"

Pretty much unheard of in cultivation – this EXCEPTIONALLY RARE South African wildflower (also known as “Uzara”) bears a striking resemblance to its close cousin, Asclepias (“Milkweed”). Substantial 3.5” across spherical clusters of fuzzy white-edged, lime green flowers appear in late Spring or Summer followed by bright green, puffy seed pods up to 4” long and covered in curly “hairs”. Dying back to the ground with the first frost, it re-emerges in Spring with multiple upright stalks that have reached 3-4’ tall for us here along the coast (though they may get up to 5’ inland), spreading over time to form a good-sized clump. Massive, 10” wavy leaves feature showy creamy yellow ribs and veins. Great in large containers (10+ gal). Tolerates a wide range of soils including clay.
