We have 3 varieties that are ready prior to Christmas
WILSON'S EARLY - Possibly 'Burbank' x 'Cherry plum'. One of the earliest plums to ripen, but the bright red yellow fleshed fruit are relatively small
DUFFY'S EARLY JEWEL - 'Duffs Early Jewel'. Early season (follows 'Wilsons Early'). DEJ is also a small fruit, but a bit larger than 'Wilson's Early, and also has red skin and yellow flesh
SHARP's EARLY -Early mid season. A medium to large, oval, red fleshed, deep red skinned plum that is soft and juicy and has good flavour. It bears heavily on a rather low, spreading tree.
