Polystichum setiferum ‘Foliosum Superbum Kaye’
I bought this luxuriant fern in 1985 at the Lancashire nursery of Reginald Kaye. The fact that it’s still growing strong is perhaps the most admirable thing about this fern: plant it and it will stay forever. It’s a particularly fine form of the Foliosum Group and has extra leafy pinnules that often overlap to give a soft, almost woolly appearance. It is completely evergreen and tolerates quite dry places in shade. In a good soil that’s not too dry, the growth is really lush – almost one metre in diameter. Height Origin Growing conditions Part shade to full shade. Hardiness RHS H7, USDA 5a-8b. Season of interest Year round.
