Calystegia sepium – What You Need to Know
If you’ve ever walked through a garden and seen vines twining around everything, you’ve probably met Calystegia sepium. Also called hedge bindweed or morning glory, this plant can look pretty but it’s a stubborn weed that loves to take over. In this guide we’ll show you how to recognize it, why it spreads so fast, and easy steps to keep it in check without breaking the bank.
How to Identify Calystegia sepium
The first clue is the leaf shape. The leaves are large, heart‑shaped, and have a slightly wavy edge. They grow in pairs opposite each other on a thick, twining stem that can reach several feet. In early summer, the plant produces trumpet‑shaped white flowers that open in the morning and close by afternoon – a hallmark of many morning glories.
Another giveaway is the root system. Calystegia sepium sends out long, woody rhizomes underground. Those rhizomes store energy and let the vine pop up again even after you cut it back. If you dig a bit around the base and see thick, white roots spreading out horizontally, you’ve likely found bindweed.
Look where it grows, too. Hedge bindweed loves sunny spots, garden edges, fence lines, and even cracks in concrete. It’s not picky about soil – you’ll find it in clay, loam, or sand, as long as there’s a bit of moisture.
Managing and Controlling Hedge Bindweed
Stopping Calystegia sepium is all about breaking its root network. The quickest method is to dig out the whole plant, making sure you get as much of the rhizome as possible. Use a garden fork and work a few inches away from the stem, then lift the root ball. It’s hard work, but removing the underground part reduces regrowth.
If digging isn’t an option, try a repeated cutting strategy. Cut the vines just above ground level every two weeks during the growing season. The plant will keep sending up new shoots, but without leaf power it eventually exhausts its stored energy and dies off.For a chemical approach, apply a systemic herbicide that moves through the plant’s vascular system to the roots. Spot‑apply to a leaf on a sunny day and avoid runoff onto desirable plants. Follow the label instructions carefully; a little goes a long way.
Mulching can also help. Cover the area with a thick layer of newspaper or cardboard, then top it with organic mulch. This blocks sunlight and makes it harder for new shoots to push through. Check the mulch regularly and replace it as needed.
Don’t forget to keep the garden tidy. Remove any new seedlings as soon as you see them, and repair cracks in patios or pathways where seeds might fall in. A well‑maintained garden reduces the chance for bindweed to establish in the first place.
Finally, stay patient. Calystegia sepium is a persistent weed, and it may take several seasons of consistent effort to get it under control. But with the right identification tricks and a mix of manual and chemical tactics, you can keep your garden looking tidy and enjoy the good plants without the bindweed taking over.
