I was fairly astonished when the parents of these flowered last summer. I was expecting the electric violet florets but not the shocking pink involucre! I couldn't stop taking pictures of them as they developed.
In every other respect these are exactly like the normal giant cardoon but only 2 - 3ft tall with leaves about 12ins long.
Easy to grow in a well drained soil in a sunny spot.
Sold out for now. Sorry
