Back in July last year, when I was offered some colchicum bulbs, I had thought they would be great to have in my pots. A few autumn crocuses seemed like a pleasant idea - and the flowers in September/October were lovely, adding some colour when not much else was happening. However, I'm now wondering whether that autumn colour was worth it as their leaves have completely swamped the pots they're in! I'm just hoping that they'll die back soon (colchicums grow from bulbs and only have leaves from spring to early summer, during which time they store energy, before the leaves die back and they then flower in the autumn). Thankfully the tulip bulbs in the pot next door (a variety called Valentine) have been more successful!
The colchicums are responsible for the huge mass (or should that be 'mess') of leaves in the large blue pot, not quite the effect I'd hoped for:
