Detailed Information

Flower: Flower shape: irregular Cluster type: raceme

[photo of flowers] Flowers are in clusters that arise from the leaf axils, with 5 to 10 flowers in a cluster. Each flower is a typical pea shape, ½ to ¾ inch long, and creamy white to pale yellow, sometimes turning orange with age.

Leaves and stem: Leaf attachment: alternate Leaf type: compound

[photo of leaves] Leaves are compound in groups of 3 to 5 pairs, with a tendril at the end of the leaf stalk that wraps around other plants for support. Leaflets are oval to egg-shaped, 1 to 2 inches long and to 1¼ inch wide, becoming smaller at the end of the stalk. At the leaf axil is a pair of leaf-like appendages (stipules) that are generally oval, about ½ inch long and sharply pointed at the tip end. Stems are angled or round, and hairless.

Fruit: Fruit type: capsule/pod

[photo of fruit] Fruit is a flattened pea pod about 2½ inches long, containing several seeds.

Notes:

Members of the pea family can often be distinguished just by the stipules; those of L. ochroleucus are quite large compared to other species. The leaflets are also broader and rounder than most other legumes, and combined with the woodland habitat and creamy white flowers make this pretty easy to identify.

I have a patch of cream pea now in bloom (5/20/2012)in an open area of our woods, 30 feet from a south lake shore. Thanks for helping me identify--we are apparently at the west edge of its range!

Took me a while to figure out what this was, hard to locate in the local ID books. Have seen a few near Little Boy Lake in Longville, MN. In bloom the week of June 9th.
