Opal is an early European-type plum with pale yellow flesh. The variety can be deliciously sweet and flavoursome, almost like a greengage, but are usually quite a mild-flavoured plum and can be bland if grown in the wrong aspect. In many ways, the flavour reflects the early nature of the variety and is a pleasant introduction to the British soft plum season. The skin is a varied colour from yellow to purple and the fruit size is small to medium. Opal is a free-stone plum.
Opal is popular among growers due to early harvest, upto 4 weeks before Victoria.
