Q.  Could you please give me the name of this tree.

You have helped me in the past.

A. Your plant is a Pineapple Guava (Feijoa sellowiana), a cousin of the Chilean plants, Luma and Ugni. Michael Kusiak, president of the local chapter of the California Rare Fruit Growers, identified it quickly when I asked. He said, “Once you train your eye to them, you will see them all over Santa Cruz County.”

Here’s a link to a short YouTube video about the Pineapple Guava.
