Avocado trees

Right in the backyard of a Lower Nob Hill neighborhood apartments, we have two types of avocado trees. The Hass avocado tree and the Reed avocado tree. Both are around 4 stories high.

Hass Avocado Tree

The fruits of the Reed avocado tree are round in shape (like a softball) and more buttery than the Hass avocados. Both trees thrive very well in the backyard without any human maintenance. They relied solely on the rainfall for water and the soil in the backyard. The Reed avocado tree bears more fruits each year. A lot of hummingbirds hang out among these trees.

Pacific Blackberry

I saw this on a hike one weekend on the San Francisco ecology trail. This plant, also known as rubus ursinus, is native to the western part of North America. It bears white flowers and it has many prickly thorns. It probably makes harvesting the fruits tough. It attracted some Elegant Sheepmoth while I was there. According to, the plant bears sweet-tart fruits that are dark purple to black and up to 2 centimeters in length.
