Opal is a great early dessert plum. The fruit is medium-sized, yellow mottled with purplish red, with juicy, pale yellow flesh which is sweet when fully ripe, and excellent, gage-like flavour. Flavour is better if tree is wall-trained. The tree is vigorous, extremely reliable, and a heavy cropper – fruit should be thinned to prevent branches breaking and for best flavour. Very good disease resistance.
