Our garden has a small patch of woodland, with thriving trees but the ground level plants are limited, apart from snowdrops and celandines.
So we've started working on widening the number of species, beginning with some ferns. We have acquired five kinds, three native to this country, one from China I think, and one from New Zealand. Some are deciduous so their foliage dies back in autumn, others retain their leaves throughout the seasons.
Ferns tend to like shade, but in varying degrees, so we've been trying to match their position carefully to their preferences. Not sure we have it right, it's a difficult judgement, but they can be moved later if necessary.
Not all in the ground yet, but the photo gives an idea of what we are aiming at.
