Discussion

Ulex europaeus is cultivated for fodder, bedding, and hedges; the flowers are used to produce a dye. An extract from the seeds is used for tissue typing, due to its ability to selectively bind with certain types of lipids and proteins.

In Massachusetts, the species was last collected in 1931 and is likely extirpated there.
