currently unavailable Big Tree Plum From the Southwestern US-Extreme Drought Tolerance
One of the best selections for its ability to grow in high heat and still crank out the plums. Fruits are very sour and astringent. This did not stop early Americans from using them for brewing and jelly. My selections originally came from Texas.1/2 “ fruit size that are kind of a mottled red color. Because of the higher moisture levels in our soil and air Mexican plum is slow growing in Michigan. The fruit ripens very late here but is completely sour into November. Plant two for pollination. It may cross pollinate with the American plum. Height to.20 ft. Hardy in zone 5 or 6 easily.
This species needs further dispersal in dry locations throughout the U.S. The fruit is incredibly strong flavored and barely edible fresh. The strength of this tree is found in its drought tolerance and could easily be grown from seed in an orchard type setting to use as is without selection. There has to be some amazing compounds found within the fruits so evaluation from a nutritional level would be very interesting. I currently do not have fruiting trees of it but I have recently planted new plants into my field to develop more fruiting trees. The one large tree after fruiting super heavy died. Not sure if that is common but shade was crowding the tree in this area as well. Not a shade tolerant species.

Pollination Requirements |
Possibly self fertile but plant two to be safe. Will cross with the American plum. |
Soil |
Sandy, rock but adaptable. Not for wet soil. |
Climate |
Zone 5ish -9. Tolerates extreme heat. |
Ease of Cultivation |
Like the American plum real easy but the fruit is difficult to use as it is so astringent. Too much humidity appears to weaken the plant and the leaves drop early. One of the best heat tolerant species but surprisingly tolerates Michigan but might be short lived here after fruiting for 10 years or so. |
