The Stewart avocado is a cold hardy, more compact version of its parent Mexicola. The fruits are shiny black with a thin skin. The firm melting flesh is clear, bright, light-yellow shading to green toward the skin and is of excellent quality. The tree is vigorous and compact and produces good crops. It is listed as an A-Type avocado but has shown B-Type characteristics. This is an excellent avocado variety for colder areas.
