Can one start a Texas Olive Tree from the olives it produces? How can you start one. I am having difficulty finding a nursery, but do see the trees around.
This USDA Plant Profile Map for Cordia boissieri (Mexican olive) does not even admit that the Texas Olive will grow in Arizona, but that just means it has not been reported to the USDA as growing there. If you follow the plant link above, you will find these growing conditions:
Water Use: Low , Medium Light Requirement: Sun , Part Shade Soil Moisture: Dry , Moist Soil pH: Alkaline (pH>7.2) , Circumneutral (pH 6.8-7.2) CaCO3 Tolerance: High Drought Tolerance: High Heat Tolerant: yes Soil Description: Well-drained caliche, sand, sandy loam, medium loam, clay loam, clay, or gravel soils Conditions Comments: Prefers well-drained soil and full sun. Requires mild winters. Regular watering necessary to establish it, but once established within its natural range, it can be left on its own, making it a popular highway planting in the Valley."
Here is an article from the Master Gardeners of the University of Arizona Pima County Cooperative Extension on the Texas Olive. If they tell you it will grow where you are, you can probably believe them, but do note the cautions about planting it in full sun and in a sheltered location.
In an article from Desert Tropicals, we found this paragraph on propagation by seed:
"Propagation by seeds might be tricky. Best results are obtained with fresh seeds at temperatures above 95°F". Here are the comments on Propagation from our webpage:
Propagation Material: Seeds , Semi-hardwood Cuttings , Softwood Cuttings Description: Plant seed fresh or double-stratify. Take softwood or semi-hardwood cuttings in summer. Seed Collection: Collect seed when it becomes muted yellow-white or pale brown with interior seed plump and hard. Clean and air dry before storage in cool, dry location. Seed Treatment: Varies with locale and climate. Commercially Avail: yes Maintenance: Requires much water to get it established but once established it is drought-tolerant."
