DOLGO CRAB is a Siberian crab that was imported from Russia by the plant breeder, Hansen of South Dakota, and introduced in 1897. "Dolgo" in Russian means "long" and refers to the shape of the fruit. The highly-flavored crimson fruit is about 1-inch in diameter, is olive-shaped and rich in pectin. The vigorous tree grows upright with spreading willowy branches and has reddish-green, dense foliage. It is resistant to scab, cedar apple rust, mildew and fireblight. This very hardy apple ripens in late August or early September and is excellent for jellies.
