Northern Catalpa (Cigar Tree)
Emerald Cedar

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.

Emerald Cedar makes a great addition to landscapes, and is often used to form tight hedges or privacy screens. The thick scale-like foliage adds texture and colour to yards and is commonly used to line driveways. Unlike other cedars it retains its green colour throughout the fall and winter.

It is a semi dwarf species, which generally needs little pruning, but if desired it responds well to trimming. Its attractive, columnar shape and dense foliage makes it a desired landscape feature.

The Emerald Cedar won the award of merit from the Royal Horticultural Society.
