Hi — we need a tallish fern for a gap in the hedge between our tiny townhouse patio in East Van and the sidewalk. The rest of the hedge is rhododendron and various other shrubs, but there’s a spot between the fence and the trunk of a deciduous tree we want to fill. I’ve been looking for an option for a tall evergreen fern, because it’d be hard to plant a shrub in all the tree roots. At this point I’m looking at Chilean hard fern, or Blechnea chilense. Does anyone know where I could get one locally, please?
