Botanic information
Leaf: The soft textured trifoliate leaves have a long petiole and two of the leaflets are sessile with the leading one terminal on the rachis. There apexes are obtuse and the cultivar 'Variegatum' has whitish margins.

Flower: The tiny creamy-white rotate flowers are arranged in a flat umbel that is up to 60mm (2½in) wide and is held above the foliage on a slender scape during summer.

Fruit: The small fruit is schizocarp (a dried fruit that breaks into sections). The small seed is not commonly seen and the plant is normally reproduced vegetatively.
