COLOSSAL
Product Description:
This European and Japanese hybrid is on grafted rootstock, reaching heights up to 30 feet, and withstands temperatures down to -20˚F. The trees flower from mid-June to early July. Male flowers have large panicles of showy white nectar rich flowers that attract hummingbirds and pollinators of all kinds. These long fuzzy creamy white flowers are fragrant and pollen producing while the female flowers have ornamentally interesting spiky flower structures which will become fruit bearing in the third year once pollinated, ripening in the fall. Zones 4-9. We recommend at least 2 trees for optimal chestnut production.
