Russian Olive vs Northern Catalpa (Cigar Tree)
Elaeagnus angustifolia
Catalpa speciosa
Russian Olive is a medium-sized deciduous tree that has attractive silvery coloured foliage with small yellow flowers that emit a fragrant sweet smell.
It is drought and salt tolerant, and works well as a shelterbelt species. Russian Olive can also be used to combat erosion.
Note: although Russian Olive is planted as an attractive boulevard tree in many northern areas, in warmer areas it can invade watersheds and is considered invasive. Please do some research and plant the right tree in the right place.
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.
