Field Bindweed (Convolvulus arvensis) can be differentiated from Hedge Bindweed (Calystegia sepium) by the smaller, often pink, flowers on plants that creep along the ground on verges, waste ground and hedge bottoms. The plant is known to contain alkaloids that affect other species, such as horses and mice, if they eat large quantities. The effects on rabbits are unknown but it is a plant that is best left alone.

Wild cherry (Prunus avium) is a common tree in UK. The leaves contain cyanogenic glycoside. The leaves, twigs and branches should not be offered to rabbits.

Celery leaved buttercup (Ranunculus scleratus) grows in wet and moist places, such as ponds and streambanks. It classed as toxic to humans because it contains an irritant that can cause blisters in humans that touch it. There are no reports of problems with rabbits.

Lesser celandine (Ranunculus ficaria) is a common spring plant that grows from root tubers. It is a member of the buttercup family, so, theoretically, it might be poisonous. It is better left alone when foraging for rabbits, although it will not matter if a few leaves make their way into picked forage because the leaves are not palatable, and they will be left uneaten.

Buttercups are often included in lists of poisonous plants because, during its flowering stage, the plant contains a toxin, protoanemonin, which is released when the plant is crushed. It is a volatile, bitter, yellow oil that is prone to spontaneous polymerization to yield innocuous anemonin. Protoanemonin is degraded by drying, so hay containing dried buttercups is safe. Rabbits do not eat buttercup leaves and there are no reports of buttercup poisoning in rabbits. There are reports in other species in situations where buttercups are all that is left in overgrazed fields and the animals eat them out of desperation.

In the UK, two types of burdock, Greater burdock (Arctium minus) and Lesser burdock (Arctium lappa) may be found on waste ground, verges, and hedgerows. The picture shows Greater Burdock. It is a large plant with big leaves. Although the plant is not poisonous, the seed heads can cause problems as they are large and stick strongly to clothes and animal fur.

The greenish flowers of white bryony (Bryonia dioca) are followed by bright red berries in late summer. The berries are poisonous.

Bryony (Bryonia dioica) is a climbing plants that can be found in hedgerows mixed with other plants. It is toxic to humans and can cause skin irritation if juices from the plant come in contact with the skin. It is not a suitable forage plant for rabbits.

Giant Hogweed (Heracleum mantegazzianum) is a dangerous plant for humans. It contains toxic sap that can cause severe burns. It can grow as tall as 20 feet with huge leaves. It can be confused with native hogweed when not fully grown or when growth is stunted (e.g. regrowth after cutting). The shape of the leaves is different and they are bristly. The stem has red blotches on it (like many toxic plants. Giant hogweed is not native to the UK. It was first introduced as an ornamental plant and has spread thorough the UK. Giant hogweed should be destroyed as soon as it is identified. It is listed under Schedule 9 to the Wildlife and Countryside Act 1981 with respect to England, Wales and Scotland. As such it is an offence to plant or otherwise cause this species to grow in the wild. Under the Environmental Protection Act 1990, giant hogweed is also classified as controlled waste. The photo shows a plant growing on an allotment. Bags have been put over the seedheads to prevent the seeds spreading while the plant is dying from the effects of the herbicide it has been sprayed with.
