eucalyptus globulus

Published on by HashiLeave a comment

The blue gum Eucalyptus globulus, native to southern Australia, is one of the most widely planted eucalypts in the world*. The bark is mostly smooth, seasonally cream to pale grey to orange-tan, shedding in long strips which often remain hanging in the canopy. The trees are very fast growing (up to 60m tall), and tolerant of salt-laden coastal winds and cold temperatures.

The species has naturalised in California and become invasive in coastal areas. We have several advanced trees on our block; I don’t know whether they self-seeded or were planted by the original owner. Even though they don’t ‘belong’ here, and they drop fire fuel, we kind of love them …

The art of soil

Published on by Hashi1 Comment

My daughter gifted me the four pan mineral suite from The Art of Soil. The pigments behave a little differently to regular watercolours, so I’m enjoying playing with them to learn their properties and how best to use them. They are very muted and grainy, which I love. They can be mixed with other brands to good effect. (The bright green above includes some Daniel Smith green gold.)

heteromeles arbutifolia

The toyon berries are putting on a good show right now. This is the shrub for which Hollywood is named, though it’s not a type of holly at all. Toyon (Heteromeles arbutifolia) is a prominent component of the coastal sage scrub plant community, and a part of drought-adapted chaparral and mixed oak woodland habitats. It is the sole species in the genus Heteromeles.

Butterflies, bees and hummingbirds love the summer flowers, and the autumn berries are devoured by a large variety of birds, including cedar waxwings, quail, towhees, Western bluebirds, robins, and mockingbirds.

Erythrina fusca

The coral tree (Erythrina fusca) is the official city tree of Los Angeles, and is widely planted in frost-free areas. We have large one at our place, and while it needs annual pruning, we never cut back as far as this specimen. I feel sad for street trees that get pruned to within an inch of their lives.

phyllocnistis citrella

The citrus leafminer is a very small, light coloured moth that arrived in California from Mexico in 2000 and has now spread throughout most of California. I’ve never seen an adult, but the larval action is very evident in my yard, especially on the young lime trees. They only infest fresh growth, which of course is just about all a little tree has!

I’ve been removing the affected leaves, but today I read that it’s not a good idea, because it just creates even more fresh growth for the larvae to mine. Apparently the insects will die off over the cooler months; here’s hoping, too, that natural predators come along to help create balance.

Twenty 7-12 year olds (and their parents) now know the difference between a valley oak and a coast live oak, though hopefully that’s not the only thing they gained from our time together 🌿💚
