French, Spanish, Mediterranean and common brooms are the most familiar of the brooms because they are among the most invasive and aggressive of weeds in rural areas. Many other brooms (that are primarily within the two genera of Cytisus and Genista) that are tame enough for home gardens unfortunately share the bad reputation, even though many of the modern varieties are hybrids that do not even produce viable seed. Once established in sunny, well drained sites, brooms are not at all demanding.
Broom bloom is almost always bright yellow, although a few varieties of broom have white, pink, pale orange or even purplish flowers. Most have finely textured evergreen foliage. Others are foliated only for a short time in spring before they drop their foliage in early summer to reveal distinctive bare green stems. The most popular modern varieties are fluffy, low shrubs less than four feet tall. Some of the more traditional types get taller than ten feet.

It’s a beautiful picture. I like seeing broom here. I marvel how we seem to have some type or other in flower all year round. It does grow wild and flourish, but doesn’t seem to take over.

The particular specimen that I got the picture of happens to be a species that is not invasive here. However, like the invasive species, it grows and dies fast. Individual specimens of the invasive species last only two or three years as they replace themselves with countless progeny. The specimen in the picture last more than five years, but no longer than ten. I suspect that it was planted by someone who brought the seed from Italy.
