Our 12 year-old stone oak, Lithocarpus glaber is looking fabulous this month, as it has come into full flower in early September. We love the stone oaks, which contrast to regular oaks in the genus, Quercus, by having upright insect-pollinated flowers, compared to wind-pollinated, drooping flowers in the genus Quercus, and by having exclusively evergreen foliage. Lithocarpus glaber is native to China, Japan, and Taiwan.
Fantastic! What’s its hardiness? Is it also wind pollinated or attractive to pollinators?
Winter hardiness is probably Zone 7b and warmer. Pollinators are a primarily a huge array of beetles, with some bees and flies.
