Today I read about a few plant species in California.

I reviewed three species of live oak: canyon live oak, coast live oak, and island live oak. The last is only found on the channel islands.

Also learned about black walnut trees. Theyare reportedly used as rootstock in orchards of non native walnut trees. I don't fully understand what that means, but I am imagining the trunk of the orchard tree being grafted onto the stump of black walnut.

Re-learned about creosote bush. These plants live in the desert and are very old. Some of these organisms are estimated at 10000 years old. They germinated when the climate was very different.

I learned about a couple small trees: Rhus integrifolia (lemonade berry) and Rhus ovata (sugar bush). They grow from 1-10 meters, are evergreen, are highly drought tolerant, and produce small berries that birds like to eat. The integrifolia one is smaller and can be trained to grow in a specific way more easily than the ovata. But the ovata can be toppedtopped without much issue. The wood is very dense.

I learned about Toyon, which is in the rose family and produces fruit similar to apples or rose hips. Reportedly, the fruit contains compounds that help prevent Alzheimer's.

In my front garden is a "Bradford" pear tree. I recently pruned it.
