Karwinskii is a winter blooming large caney plant. The species seems to be the one which has felted white stems and under the leaves and pinky reddish flowers late winter. It will be 2-3m high. However it seems to be very promiscuous and there are a number of variations.
From my original seed I kept one which seems to stay at about 1.5m with peachy pink flowers and a similar size one which has cyclamen pink flowers. These two start flowering about the beginning of winter. There is another in Australia called ‘Winter Red’.
I don’t know who introduced the very large one which may be the species. This is the latest to flower that I have. Then there is the one I named ‘Winter Lipstick’ that I sold for a long time as involucrata x karwinskii, rather a mouthful for most people and needing a common name. This is very long flowering for me, from May to November, although a heavy frost could set it back. Because it flowers for such a long time it can recover from the frosting and flower again. This is listed on its own. “Timboon’ is similar to ‘Winter Lipstick’ and an excellent plant.
Usually have various karwinskiis for sale but stock is moving out fast.
