It grows in sunny places and can be very tall, making it a great home for birds and other animals. - **Category:** [Plants](https://www.snappit.app/explore/categories/plant) - **Rarity:** Common - **Danger:** 2/5 · Low - **Snaps:** 25 - **Habitat:** Coastal areas ![California buckeye](https://commons.wikimedia.org/w/index.php?title=Special:Redirect/file/Aesculus_californica-12.jpg&width=800) Photo: Eugene Zelenko, CC BY-SA 4.0 · [Wikimedia Commons](https://commons.wikimedia.org/wiki/File:Aesculus_californica-12.jpg) ## Appearance The California buckeye is a deciduous tree with a striking dome-shaped crown and smooth, grey bark. Its large, palmate leaves, divided into 5-7 leaflets, turn golden in summer before dropping early. Showy clusters of white to pale pink, fragrant flowers bloom upright. ## Taxonomy - **Kingdom:** Plantae - **Phylum:** Tracheophyta - **Class:** Magnoliopsida - **Order:** Sapindales - **Family:** Sapindaceae - **Genus:** Aesculus ## Interesting facts - Even though its nectar is toxic to European honeybees, native bees and hummingbirds love it! - It's one of the first trees to drop its leaves in California, often by mid-summer! - Native Californians once leached toxins from the seeds to safely use them for food! - The 'buckeye' name comes from the seed's dark spot, looking just like a deer's eye! ## Special abilities - **Early Sleep Mode:** California buckeye has a unique ability to drop its leaves in summer, entering early dormancy to survive long, dry California summers without water. - **Potent Poison:** California buckeye produces toxic compounds in its leaves and seeds, protecting itself from most herbivores who would otherwise eat its parts. - **Seed Supercharge:** California buckeye grows very large seeds that store ample energy, allowing new seedlings to establish quickly in challenging, dry conditions. ## Measurements & details - **Height:** 400-1500 cm - **Spread:** 400-1000 cm - **Flower Size:** 1-2 cm - **Bloom Season:** Late_spring_to_early_summer - **Edible:** No - **Toxicity:** High - **Lifecycle:** Perennial - **Pollination Method:** Insect ## Ecological connections - **Pollinates:** Yellow-faced bumblebee (*Bombus vosnesenskii*) — Provides vital nectar for native bumblebees. - **Pollinates:** [Anna's hummingbird](https://www.snappit.app/explore/annas-hummingbird) (*Calypte anna*) — Hummingbirds feed on its abundant, nectar-rich flowers. - **Eaten by:** [Western gray squirrel](https://www.snappit.app/explore/western-gray-squirrel) (*Sciurus griseus*) — Squirrels consume its toxic seeds after careful preparation. ## Traits - [Deciduous](https://www.snappit.app/explore/traits/deciduous): Deciduous plants periodically shed all their leaves, typically during autumn or dry seasons. - [Flowering](https://www.snappit.app/explore/traits/flowering): Flowering plants are any plants that produce flowers as part of their reproductive cycle. - [Broadleaf Tree](https://www.snappit.app/explore/traits/broadleaf-tree): Broadleaf trees are angiosperms characterized by flat, wide leaves that are typically shed annually in temperate climates. - [Fragrant Flower](https://www.snappit.app/explore/traits/fragrant-flower): Fragrant flowers emit a pleasant aroma, often to attract pollinators or for defense. - [Nut Bearing](https://www.snappit.app/explore/traits/nut-bearing): Nut bearing plants produce hard-shelled fruits, commonly known as nuts, which contain a single seed and are a valuable food source. - [Fall Color](https://www.snappit.app/explore/traits/fall-color): Fall color refers to the seasonal change in foliage pigmentation, primarily in deciduous plants, displaying vibrant hues. - [Pollinator Magnet](https://www.snappit.app/explore/traits/pollinator-magnet): Describes plants that are particularly attractive and beneficial to a wide range of pollinating organisms. - [Coastal](https://www.snappit.app/explore/traits/coastal): Coastal habitats are dynamic environments located along the interface between land and sea, influenced by tides, waves, and saltwater. ## Collections - [Plants](https://www.snappit.app/explore/collections/plants) ## Safety **Danger:** 2/5 · Low Don't eat the seeds of the buckeye; they can make you feel sick. ## Frequently Asked Questions ### How to identify California buckeye? Start with the whole plant, then compare leaf arrangement, leaf edges, stems and any flowers or fruit. Opposite leaves grow in pairs; alternate leaves come one at a time along the stem. These details tell you far more together than a single green leaf does.
