Fabaceae: Pea Family — Broom
The pea family has 5-petaled flowers, consisting of a wide upper banner petal, two wing petals, plus two lower petals which are fused to form a boat-shaped keel. Many produce heads or spikes, consisting of multiple individual flowers (examples are lupines and clovers). The seed pod is generally a “legume”. This is a long, flattish pod, swollen by the seeds, and splitting lengthwise along both the top and bottom.
This page shows three highly invasive plants. In particular, French Broom has an adverse impact on the landscape in parts of the Monterey Peninsula. It should be eliminated wherever it is found, no matter how pretty it may appear when in flower.
