Learn more about bottlebrush buckeye
Bottlebrush buckeye is actually a type of bushy horse-chestnut tree that has more or less the same leaf and flower characteristics as its larger cousin.
It thus makes for easy growing and care and will fit just as well in a shrub bed as it will as a standalone.
If in a shrub bed, do provide for sufficient space because once mature it can grow wider across than 25 feet (8 meters)!
Are the fruits edible?
Unlike chestnut, bottlebrush buckeye fruits are only edible after special treatments: roasting, then slicing, and finally soaking in running water for days on end. It contains high levels of saponin, a poisonous compound that must be washed out from the dried, powdered or sliced material. Since this treatment also removes other nutrients, it isn’t much worth the effort.
- These same saponins can be used to make soap, though, so it’s still an interesting plant to keep!
