TRUEBLUE ™ HOH 4528 (S)
Plum, Prunus domestica
TRUEBLUE ™ is a late-ripening plum novelty which, despite severe late frost damage in recent years, has produced remarkably high yields with good fruit sizes.
The fruits are attractive in shape and colour and have a high cracking stability. Initial cultivation experience also shows no tendency towards stone splitting or caverns.
Due to the completely free stones and the good flavour, the fruits of TRUEBLUE ™ are ideally suited for industrial processing and direct consumption.
