Ambience is a semi-leafless variety of pea.

Ambience produces petit pois, which are very small, sweet-tasting edible peas.
Petit pois may be eaten in the pod as mange tout.

Ambience pea flowers are white, with a green tinge.
The Ambience petit pois peas have few leaves but a mass of tendrils.
Semi-leafless peas have 5 advantages over the normal pea:
* easy picking – pods are easy to see as there are few leaves
obstructing the view
* stand up – masses of intertwining tendrils act as a self-support
system, improving standing, so sticks not needed
* high yields
* water use efficiency is higher.
* ladybirds are much more efficient when they hunted aphids
infesting leafless pea plants, rather than the normal variety.
Pea leaves are slippery – whereas stems and tendrils provide a
more secure footing. So ladybirds fall off the normal variety
nearly twice as often as the leafless plants.
Leafless peas have a recessive gene which produces a modification of
the common pea plant (Latin name - Pisum sativum L.) leaf morphology,
where leaflets are replaced by tendrils, reducing the foliage. The
tendrils contribute to plant growth in a similar way to flat leaf
structures.
Semi leafless peas have at least 5 advantages over the common garden pea.
