This is a large shrub, very common in chaparral, with clusters of small narrow pointed leaves (the “fascicles” which give the plant its scientific name) and a mass of tiny white flowers which produce a spectacular display in early summer. Like som other chaparral plants, Chamise is “allelopathic”, i.e. it releases a toxin that inhibits the growth of other plants in the vicinity. Like certain Manzanitas, Chamise develops a burl (although invisible because underground). This burl is a repository of dormant buds that are stimulated by fire so that the plant is able to resprout even following a fire which destroys everything that was above ground. Another consequence of the fire is that the heat vaporizes the allelopathic toxins which explains how it is possible for the fire following herbaceous plants to flourish and put on such a spectacular display in the few years following a destructive fire.
