QuoteKARAKA BLACK - The distinctly different new hybrid berry
Selected from a hybrid berry breeding programme in New Zealand, Karaka Black exhibits several valuable traits which taken as a whole have resulted in a quite unique new berry for UK gardens. Karaka Black has extraordinarily long, slender fruits which are 4 times as long as they are wide, and often up to 4 inches in length. The glossy black lustrous colouring hints at the delicately ambrosial, juicy sweet and aromatic flavour which is perfect for eating fresh, but the berries hang in prominent clusters all over the outer canes. In Growth it is very compact with a spacing of only 3-4 feet between bushes recommended. Add to this an extremely long and persistent fruiting season which starts in Mid July and will usually continue into September and unarguably, we have a new fruit just made for the smaller garden. You will love the delicately sweet, distinct flavour, the compact, high yielding growth will impress you, the very appearance of the fruits is so different, and the lengthy picking season without compare. Karaka Black - only the name could be improved upon. New and stock limited.
