Black Hills Spruce vs Northern Catalpa (Cigar Tree)Picea glauca var. densata Catalpa speciosa 
Black Hills Spruce is a subspecies of White Spruce native to the Black Hills of South Dakota. It has a strongly conical form, slower growth rate and denser foliage than typical white spruce, making it preferable as a specimen tree for smaller suburban lawns. It also responds well to pruning, and can be used as a hedge or even bonsai.
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. BLACK HILLS SPRUCE QUICK FACTSNORTHERN CATALPA (CIGAR TREE) QUICK FACTS
