Eucomis. Fertilize once a month, water regularly and enjoy. If after the foliage dies back and part of the bulb is exposed, cover with dirt or the snails will attack. Dividing is tricky. I waited for 2 years after getting new shoots because the new bulbs were too connected to the main bulb to divide. They do best in the sun - in the shade the flowering stem gets too long and it flops over.

thanks for the answer, it looks like the pineapple plant will be on the move into the glorious British sun!
