Now here’s a plant that I hadn’t seen before – Anisodontea ‘El Royo’, or Cape Mallow. Its hibiscus-like flowers persist throughout winter on this west-facing wall in Olive Mason’s garden, Dial Park – apparently they shrivel up when there’s a frost, but bounce right back again. A quick Google has revealed that you can buy it at Cotswold Garden Flowers.
It looks so fresh and summery in the winter gloom. If I had a sheltered, west facing wall, I would definitely plant one. As it is, I have an exposed, west facing wall, so I don’t think I’ll risk it.
