Bindweed is one of the common plants that can flower and cause problems in your garden.
While it may look pretty, it has been described by experts as "rampant" and can "quickly smother other plants in your garden".
Here is all to know about Bindweed, including what it looks like, when it flowers in the UK, if it is poisonous and how to remove it.
How to Get Rid of These Common Garden Pests
What is Bindweed and what does it look like?
Bindweed is a UK native wildflower, and while it can be beneficial to wildlife, its spreading roots and twining stems can cause issues in gardens.
The Royal Horticultural Society (RHS) highlights two types of common Bindweed, namely Hedge bindweed and Field Bindweed.
Hedge Bindweed has heart-shaped leaves and funnel-shaped flowers.
These are "usually white but can also be pale pink with a white centre and five white stripes".
"After flowering, rounded capsules form, each containing up to four oval-shaped brown seeds," the RHS adds.

When does Bindweed flower in the UK?
Wildlife Trusts notes that Bindweed typically flowers between June and September.
Despite Bindweed stems typically dying back in autumn, the root system remains and will be "ready to produce new shoots in spring".
Nick Wood is a horticulture expert at online garden centre Gardening Express.
He has issued a warning to Brits as we come into the seasons when Bindweed typically flowers.
Arvensis: refers to plants typically found in, or associated with, fields or cultivated areas.
From the Latin 'arvum' meaning field.

He said: "Bindweed might look pretty with its delicate flowers and heart-shaped leaves, but don't be fooled - it's a rampant twining vine that can quickly smother other plants in your garden.
"Hedge bindweed is the real culprit here, with its fast-growing, climbing stems that can wrap around and strangle anything in their path.
"Field bindweed is less aggressive, but it's still a persistent problem, especially in open soil where it can spread rapidly.
"While it's a native wildflower, its aggressive growth and spreading roots can quickly take over gardens and other natural areas, which is why it's incredibly invasive in the UK.
Bindweed UK law
Mr Wood added that while there is "no specific law directly addressing bindweed in the UK", Brits "all have a legal duty to manage invasive plants to prevent them from spreading and causing harm to neighbouring properties".
The RHS adds that while you do not need to remove Bindweed from your garden, it can spread to other plants, so controlling it is key.

It said: "If left to grow in a wildlife corner or less-cultivated area, or through a mature hedge, it will boost the variety of living organisms (plants, animals, fungi and microorganisms) in a particular environment.
"Boosting the biodiversity of your garden has many benefits, including supporting wildlife, improving soil health and reducing the likelihood of pest and disease problems. biodiversity of your garden and gives you a chance to enjoy its attractive flowers.
"It is, however, a good idea to control the spread of hedge and field bindweed as they are both capable of outcompeting and smothering other plants."
Is Bindweed poisonous?
With Bindweed being very common in the UK, it is important to know if it is poisonous to humans or pets.
Thankfully, unlike some other weeds in the UK, Bindweed is not poisonous.
Poisonous Plants Found in the UK
The expert explained: "Luckily, bindweed isn't poisonous to humans or pets, but it can be a nightmare for gardeners trying to keep it under control. This is despite the fact that its flowers can attract pollinators.
"But don't let that fact lull you into letting it run wild - the damage it can do far outweighs any small benefit."
Mr Wood also touched on how best to remove the invasive plant.

The expert warned Brits to "act quickly" if they find Bindweed in their garden.
He also issued a guide on how to attack the plant and get rid of it.

"If you leave even a tiny fragment behind, it can regrow and spread all over again.
"You'll need patience and persistence, and be prepared to keep at it for several growing seasons.
"Herbicides can work, but they often require multiple applications, and be careful not to damage nearby plants."
If you are looking to dig out Bindweed, Mr Wood recommended against it.

He said: "You can try digging it out, but be warned - bindweed has a notoriously extensive root system.
"If you miss even a tiny piece, it can regrow with a vengeance. Regular cutting and pulling can keep bindweed in check, but it's a long game.
"Persistence is key, and whatever you do, don't let it flower - that's when it spreads even faster."
