I'm recreating our tiny (10x6m) north-facing garden from scratch. I've dug a large bed which is 5.5m long and between 1 and 2.5m wide at different points. I want lots of lush, green verdant planting. We've got a fatsia japonica for starters, and I'm planning underplanting with ferns, hostas and Japanese forest grass.
I need one or two other tall plants / shrubs / plants to go with the fatsia, but am a bit stumped beyond that. Any ideas? I've considered planting gunnera, a euphorbia mellifera, possibly a small acer, but not sure any of these are quite right. We've also got a left-over choisya ternata sundance from the old garden, but it's a bit mangled and I'm not sure it works. Possibly some clumping bamboo? All ideas gratefully received!
