One way in which the eucalyptus, mainly the ******** E. globulus, proved valuable in California was in providing windbreaks for highways, orange groves, and other farms in the mostly treeless central part of the state. They are also admired as shade and ornamental trees in many cities and gardens.
Eucalyptus forests in California have been criticised because they compete with native plants and do not support native animals. Fire is also a problem. The 1991 Oakland Hills firestorm which destroyed almost 3,000 homes and killed 25 people was partly fueled by large numbers of eucalypts close to the houses.
In some parts of California, eucalypt forests are being removed and native trees and plants restored.
I already have some eucalyptus saplings. I can take the Vicks smell, and I already have a cat that marks all the stuff around here, not to mention a crape Myrtle that is shedding all over the place. Also we have acreage that we can plant them on far away from the house. Most of the ground under the native pines is barren too.Many people consider these a "nuisance" tree. They're hugely messy, dropping flowers, seedpods, and tons of stringy bark all over the place. They smell like a mixture of Vick's Vapo-Rub and cat pee. They are allopathic, and crowd out/poison other plants. The ground under one of these trees is usually a barren wasteland.
So, no. I wouldn't plant these trees.
Beekeepers plant all kinds of things that are not native, Vitex is a example. In fact, the invasive ones seem to be the ones that produce the most honey.These trees have no natural place in the American ecosystem, and many have become invasive pests, crowding out native trees.
