lola-lemon - this particular ornamental kale/cabbage would be white even outdoors. It isn't light starvation which has made it so. They are widely used as winter bedding plants in cool climates. Bringing an ordinary culinary kale/cabbage inside would not have the same effect. The one in the picture is already opening some of its typical yellow brassica flowers.

Yes, that is. Thanks you

Its a Clivea. In time the flower spikes with get higher than that. They prefer shade and moisture but are very hardy. Ive had a heap of them in a big root ball in some shade for a year above ground. Im waiting for the driveway to be fixed. There is a caterpillar that eats them if there outdoors however ive only had it twice in 15 years. Confidor works as a treatment but spray when not in flower as it is harmful to bees. Theres a few varieties out now of different colours. Very nice hardy plant that flowers every year for me. hope this helps Tim
