About Ruby Horsechestnut
Deep pink candles in late spring on a smaller, tidier tree than the common horsechestnut. It also sets far less fruit, which matters if you have ever cleared conkers off a drive. Much less prone to the leaf blotch and leaf miner that make white horsechestnuts look ragged by August.
