Common Ivy (Hedera helix) is common indeed and has flowered very early. I saw it in flower in London in mid-August and not long after in Hertfordshire. This is undoubtably a response to the prolonged drought and heatwaves; many plants have flowered earlier and for briefer periods this year.

 Typically Ivy is in flower September/October/November feeding various pollinators well into autumn including honey bees. Ivy honey is known for its dark colour and deep flavour. My bee keeping friends are worried the Ivy season will be cut short and with it the honey.
