The Eureka Raspberry
This was the first of Mr. Burbank's crossbred raspberries to be perfected. It was introduced in 1893, and was described as "larger than any raspberry in cultivation"; bright red, very productive, and similar to Schaffer's Colossal in its piquant acid flavor." The experiment through which the Eureka was produced furnished invaluable lessons in heredity.
