Wildflower of the Week: Hedge Bindweed

I haven’t written a Wildflower of the Week post for a while as there are not too many wildflowers in bloom at this time of year. There is still Hedge Bindwood in flower however.

Hedge Bindweed grows rapidly, twining anti-clockwise as it grows upwards, smothering out other plants. On a warm day when it is growing rapidly, it can twine a complete revolution in an hour. It’s not popular with gardeners being a pernicious perennial weed. If you try to dig it out and leave the tiniest fragment of root behind it will grow back!

The plant is hairless with arrow or heart-shaped leaves.

The large white flowers are trumpet shaped, formed from five fused petals.

The flowers are popular as a source of nectar for bees, butterflies and moths, including night-flying moths as the flowers do not shut at night. Hedge bindweed is the food plant of the Convolvulus Hawkmoth.

The plant is toxic, containing alkaloid chemicals that have a purgative effect. It is also considered harmful to livestock and thought to cause colic in horses. The stems are tough so can be used as string in an emergency.

The plant has many country names including Windweed, Devil’s guts and Granny-Jump-Out-of-Bed. Children played a game, squeezing the calyx and making the flower “jump” off the end, giving rise to that name.

As one of the few wildflowers still about in October (and quite an exotic looking one) Hedge Bindweed is quite a welcome sight….unless you are a gardener!
