Purple Passion' is a woody-based, evergreen perennial. The dark green leaves and stems are clothed in bright purple hairs, especially on the undersides. The thistle-like flowers are egg-yolk yellow, with a purple calyx, appearing mostly in winter
Grow indoors in a loam-based potting compost in bright, filtered light. Train up a support, or pinch out shoots to keep more compact and encourage new shoots.
