Catalpa Trees as a Nectar Source
Catalpa trees are native to the Midwest, but have been cultivated for so long it is difficult to determine what their original range was. This is a fast growing, medium sized tree; generally reaching 60 feet in height. The trunks of older trees have a gnarled, twisted appearance. Flowers appear as large, upright clusters of white petals with purple and yellow spots in May and early June. Identification of a catalpa tree is not difficult. The leaves are heart shaped and may be up to a foot long. The flowers are large and showy. After flowering the tree develops seed pods that can be several feet long and often remain on the tree over winter. The flowers produce abundant nectar and this tree is readily worked by bees when in bloom.
