This is a lovely mec, with dissected leaves and pale yellow flowers. It is monocarpic and about the same size as horridula, I would say treat it as horridula, if you grow them. It might be difficult to get to planting size, keep the seedlings well shaded with fleece and don't let them get too hot, then plant out in a cool position in the garden. If you sow them now they should germinate within about 4 weeks, once they are starting to germinate keep them frost free. Good luck with them.
