Bought this last year at a garden centre and it had lush large leaves and not a lot else, potted it up and near enough forgot about it. It did really well and then this year suddenly keeled over. I've replanted it in the ground, having found a dense overcrowded rootball in the pot and now it has this mound of ?failed flowerheads (looks more broccoli like than what I bought last year!!!).
The trouble is I have zero recollection of what it's called, so not sure how best to revive it!
Any ideas? It's not an Acer is it?
