CA buckeye ~ 12/10/11 ~ Los Padres Dam

California buckeye
Aesculus californica
more information
Sapindaceae (formerly Hippocastanaceae)

I wanted to show how big our CA buckeye seeds get, much larger than the native buckeyes (A. glabra and A. flava) and introduced horse chestnut (A. hippocastanum) seeds I found when I lived in Ohio. During our hike, we had a fun time rolling the prolific seeds down the ravines to see how far they would go; it was like rolling bocce jacks over a rough terrain.

I'm surprised I don't have additional seasonal posts of the CA buckeye, considering it's noticeably one of the first trees to sprout leaves in late winter and one of the first trees to drop leaves in late summer, which I read somewhere was due to lack of water. I'll have to rectify this posting deficiency. For much better information than I could ever provide, check out Clare's buckeye post at Curbstone Valley Farm.

bigleaf maple and CA sycamore ~ 11/19/11 ~ Garland Ranch

Both these deciduous trees are native to California and provide lovely autumn colors. They can be quite tall, so it's difficult to compare the shapes of the leaves when they're too high to examine. It's taken me until this hike, when the forest floor is littered, to truly distinguish the leaves. For the longest time, I thought Garland only had one native large-leaved tree, that being the bigleaf maple. I was wrong. Considering the place used to be a ranch, I figured any sycamores I found were non-native. I've corrected past posts to reflect my new understanding, like last November's Garzas Creek habitat post.

Acer macrophyllum
Sapindaceae (formerly Aceraceae)

Notice the 5 deep lobes of the leaf? The vertically grooved bark, often covered in moss or lichen, reminds me very much of walnut trees. Other eastern North American counterparts are red maple (Acer rubrum), silver maple (Acer saccharinum), and sugar maple (Acer saccharum). Despite what the USDA PLANTS database shows, the silver maple is not native to CA.

What originally confused me about the leaves is the CA sycamore's can have 3 or 5 lobes. I can usually recognize sycamore bark by its sickly, puzzle-like look - yep, that's my own highly technical description. Its eastern North American counterpart is American sycamore (Platanus occidentalis).

In a previous post from this summer, I showed how big the CA sycamore leaves get, which can be considerably larger than the bigleaf maple. Happy fall!

ps 11/29/11 - I'm glad I don't have to deal with the differences between sycamore maples and field maples like they do over in the UK, The Squirrelbasket and Loose and Leafy.

CA buckeye ~ 05/23/09 ~ Fort Ord

California buckeye
Aesculus californica
Sapindaceae (formerly Hippocastanaceae)

 I never really looked at the blooms up-close before. They're beautiful! My friend told me the California buckeye is poisonous to European honeybees (Apis mellifera), but not to our native bees. I was surprised to hear this. Has anyone else heard this?
