Plums have been planted in Southern Humboldt since the homestead period, and some old trees miraculously survive. Commercial prune orchards were attempted in the early days, but disease problems caused most of these to be abandoned or replaced with apple trees.
Here at Greenmantle, we have focused our attention on the various European types of plum (prunes, gages, etc.) rather than the Japanese hybrids like Satsuma and Santa Rosa. The Japanese plums as a class tend to bloom a few weeks earlier than their European counterparts, making them very vulnerable to late frost and winter storms. They are also more susceptible to bacterial and fungus problems.
We graft our plum varieties on myrobalan seedling which makes a full-size standard tree requiring about 18 feet of space.
Plums on myrobalan seedling can handle wet, heavy clay soils better than other types of fruit. While breeders are working on the issue, the currently available selection of dwarfing rootstocks for plum do not seem reliable or healthy enough.
All varieties listed below are self-fertile & don't require pollination from other trees.
DAMSONS Briceland Damson
Pearl Prune .................................... Kirke's Blue Plum
The outstanding prune of our collection is the Moyer, a very large
Italian-type with orange flesh; excellent fresh or dry.Other prunes of
special interest are French Petit, the classic "unimproved" variety which we collected from a very old orchard;
Not so long ago, the Green Gage plum was the best known and loved plum in Europe and America. It is now heading for extinction in this country, largely due to trueness-to-name problems that have made the real Green Gage hard to find. We recovered ours from an original homestead tree documented to have been bought from Oregon Nursery Company (ORENCO) in 1905. Green Gage may be too fragile for commerce, but this fact - and its superlative flavor - make it an indispensable addition to any home orchard.
Our Briceland Damson is an almost wild form, collected from a naturalized thicket on the banks of Miller Creek in Briceland. This is the traditional variety for jam and other culinary uses.
