Like its tough green-yellow cousin Euphorbia polychroma, 'Chameleon' grows well in average, dry to medium moisture, well-drained soil in full sun to light shade. It produces its best purple leaf color in full sun. It tolerates poor soils that are somewhat dry; it does not thrive in extreme humidity.
I love to see this plant contrasted with the chartreuse foliage of Lysimachia nummularia 'Aurea' (Golden Creeping Jenny) or the grey leaves of Artemisia ludoviciana 'Silver Queen' (Western mugwort 'Silver Queen'). It has an attractive way of blending within a border.
