Loganberry
The loganberry ( Rubus × loganobaccus ) is an American hybrid of a blackberry and the raspberry . It originated in California by chance and is now a valued crop.
features
The loganberry is a deciduous shrub that grows up to five meters high, its growth corresponds to that of the blackberry. The shoots are almost round and densely covered with straight, protruding spines, the moderately coarse leaves are three or five times pinnate, their edge unevenly to almost doubly serrated. On the dark green upper side there are scattered hairs, on the underside the leaf is covered with gray tomentose hair. The unpaired leaflet is round, heart-shaped to weakly three-lobed, blunt or with a broad tip, the lateral leaflets are sessile.
The inflorescence is equilateral. The long flower stalks are tomentose and covered with protruding spines. The flowers are hermaphroditic, the male flowers are larger than the female. The long-pointed sepals are ovate and lanceolate, the petals large and white, the carpels finely downy-haired to almost tomentose. The fruits are elongated, red and sour aggregate drupes .
The loganberry is self-fertile, but the fruit is usually set by apomixis . It is propagated through seeds. The number of chromosomes is 6n = 42.
Origin, use
The loganberry was probably created by crossing Rubus ursinus with the raspberry variety 'Red Antwerp'. It was created in Santa Cruz , California in the garden of Judge J. H. Logan, to whom the name refers.
Today the loganberry is a valued crop for its edible berries, which is also grown commercially. There are several varieties, important among others 'Phenomenal', 'Thornless Logan' and 'Thornless Young'. Besides Rubus flagellaris 'Lucretia', the 'Phenomenal' variety is a parent of the young berry . The stingless, tasty 'LY654' is also valued.
The fruits are processed into preserves or wine, among other things. The main growing areas are the states of Oregon and Washington . It is also grown in England and Tasmania. The location should be well moistened, but not waterlogged, and partially shaded to sunny.
The loganberry has grown wild in Western Australia and grows there along streams and in undisturbed locations.
