We get a lot of questions on our social media channels, and one that has come up often is which flower type (Type A or Type B) a specific variety of avocado is classified as.
Avocados are a unique fruit that uses a system called protogynous dichogamy. Where the flower opens as Female on one day, and then Male on the next day (Type A). Or the opposite (Type B)
We've gone ahead and put together a chart for you for easy reference, indicating the Variety, Flower Type, Parentage, USDA Zone, and Cold Hardiness (when the tree is mature)
As always, we welcome questions and look forward to GROWING TOGETHER!
