Here are some interesting old plum varieties found on a semi-abandoned orchard in Lake County, California along with a wide variety of other fruit and nut trees.
I came across this solitary Jubaea chilensis planted in a town near where I live. In the autumn it produces massive quantities of seed. The Jubaea chilensis palm has one of the most monumental trunks of any plant in this family. The thickest well - documented trunk was 66 inches in diameter. Of the more than 2,600 known species of palms. J. chilensis is the second most massive, exceeded only by the floodplain or river bottom variety of Borassus aethiopium. The round seeds resemble miniature coconuts, with an edible coco meat and liquid in the center.
I am currently trying to germinate 150 seeds collected 9 months ago.

I encountered this Mexican hawthorn tree at the Gold Ridge Experimental Farm in Sebastopol, CA - Luther Burbank’s former laboratory. Although much of the acreage has long been converted to housing development and only a small tract of the former farm remains, there are some interesting trees surviving. One area I return to whenever I visit is the small group of Cratageus species in the back where a few species, including C. mexicana, are still thriving.
Compared to the Chinese Hawthorn, C. pinnatifida, the Mexican hawthorn tastes much better out of hand and has an interesting aroma, reminiscent of some obscure tropical fruit or synthetic bubblegum.
The fruit of Crategeus mexicana is eaten in Mexico cooked, raw, or canned. It resembles a crabapple, but it has three or sometimes more brown hard stones in the center. It is a main ingredient used in ponche, the traditional Mexican hot fruit punch that is served at Christmas time and on New Year's Eve. On Dia de los Muertos tejocote fruit as well as candy prepared from them are used as offerings to the dead, and rosaries made of the fruit are part of altar decorations. A mixture of tejocote paste, sugar, and chili powder produces a popular Mexican candy called rielitos, because it resembles a tiny train rail.
In some parts of Mexico, tejecote is taken for treating flu and cough, and also to prevent several cardiovascular diseases.
Due to its high pectin content, the fruit is industrially processed to extract pectin for the food, cosmetic, pharmaceutical, textile and metal industries.
Other uses include food for livestock (for which the leaves and fruits are used) and traditional medicinal uses; a Mexican hawthorn root infusion is used as a diuretic and as a remedy for diarrhea and fruit-based preparations are a remedy for coughing and several heart conditions.
The Mexican hawthorn tree's wood is hard and compact, it is good for making tool handles as well as for firewood.
I first encountered this spectacular quince species at the Burbank Experimental Earm in Sebastopol, California. Notable for its massive fruit, which is at first a light green then turning yellow as it ripens. Among the apples, Sorbus domestic, and a number of other surviving Burbank species this one seems to be growing strong and quite productive.
The tree is a deciduous, semi-evergreen tree in the Rosaceae family (Rose, Pear, Apple, Loquat). Native to Eastern Asia in China this is the sole species in the Pseudocydonia genus. Previously Pseudocydonia was placed in the Asian genus Chaenomeles, however differs in that Pseudocydonia lacks thorns and produces single flowers. The Chinese Quince is closely related to the European Quince, Cydonia bologna. The two species differ in that Chinese quince has somewhat serrated leaves and smooth fruited skin. The fruit on the Burbank Hybrids also appear to grow larger.
The tree is referred to as mùguā-hǎitáng (木瓜海棠).In Chinese, mùguā (木瓜) also means, “papaya”.
Grows 8-10 m long. The fruit is a large ovoid pome 12–17 cm long with five carpels; it gives off an intense, sweet smell and it ripens in late autumn.
The large fruit is hard and astringent, however after a period of frost the fruit does become a bit softer and less astringent. The fruit can be used in the same way as quince, poached, baked or used for making jam. The tree is also grown as an ornamental in Southern Europe.
In Korea it is used to make a preserved quince and quince tea.
The bark and trunk of larger trees are highly ornamental. The wood is frequently used in Japan for shamisen, a three-stringed traditional Japanese musical instrument derived from the Chinese instrument sanxian.
The fruit is used extensively in Traditional Chinese Medicine to treat rheumatoid arthritis. Recent pharmacological studies suggest that extracts of phytochemical in the fruit have antioxidant and antiviral properties.
