Dragon Spruce vs Northern Catalpa (Cigar Tree)
Picea asperata
Catalpa speciosa
Dragon spruce is a unique looking spruce, as it is more shaggy and irregular than most spruces. They have sharp, stiff needles that are directed forward on the branch and their colour ranges from grey/green to blue/green.
They will grow in nutrient poor soils and can tolerate stronger winds, making them a good choice for providing shelter.
This species has been declining due to deforestation and related human activity in western China, its native range. It has notable genetic diversity for a spruce with a number of unusual growth habit variants. Given the cultural significance of the dragon, this tree should not be underestimated for its beauty or usefulness.
Northern Catalpa is a striking feature tree with showy flowers, and very large leaves. Its orchid-like flowers are white with yellow and purple accents, and they have a pleasant fragrance. They bloom from late spring to early summer and can last up to two weeks, attracting hummingbirds and pollinators. The leaves are very large, ranging from 15-30 cm long, 12-20 cm wide, forming a canopy that makes it a good shade tree.
They can tolerate dry conditions as well as standing water, air pollution, and salt. These factors and its beauty contribute to its growing popularity as both a boulevard and ornamental tree in colder areas.
Northern Catalpa produces long bean-like capsules and are sometimes called the Cigar Tree in reference to this fruit.
