Pin Oak 'Green Pillar'
FamilyFagaceae
Quercus palustris ‘Green Pillar’, also known as columnar pin oak, is a vertical ornamental selection of the pin oak, ideal for structuring confined or modern spaces. With its naturally narrow fastigiate habit, it forms a dense green column in summer that transforms into intense red in autumn, offering a strong and graphic presence in informal hedges, rows, or as a specimen tree. This hardy variety, well-adapted to the Quebec climate, tolerates several types of soil as long as they are well-drained, and requires little maintenance. Its architectural appearance makes it a preferred choice for urban courtyards, narrow vegetative screens, or contemporary gardens. In addition to its seasonal visual interest, it attracts butterflies and insects, thus enriching local biodiversity while elegantly structuring the space.
