Development, use

The Loganberry probably originated from the crossing of Rubus ursinus with the raspberry variety ' Red Antwerp '. It originated in Santa Cruz, California in the garden of the judge JHLogan referred to by the name.

Today, the loganberry is an estimated crop which is also grown commercially for its edible berries. There are several varieties, among other important ' Phenomenal ', ' Thornless Logan ' and ' Thornless Young'. The variety ' Phenomenal ' is next Rubus flagellaris ' Lucretia ' is a parent of the young berry. It is estimated the stingless, tasty ' LY654 '.

The fruits are processed into canned food or wine. The main growing areas are the states of Oregon and Washington. In England and in Tasmania it is grown. The site should be well moistened, but not wet congestion and partial shade to full sun.

In Western Australia, the loganberry is wild and grows there along streams and in disturbed habitats.
