Guamuchil, as we call it here in Los Angeles is virtually invasive. I have several forty foot trees on my property. My neighbors come over and harvest the fruit. They mostly eat it fresh picked. Guamuchil will grow in any soil and any light conditions. Flocks of parrots descend on my trees and have their fill. The fruit is also excellent cattle and equine fodder. A very productive and useful tree.

Pithecellobium dulce has many names, and is also known as Guamuchil. At the southern tip of Texas it serves as caterpillar forage -- a hostplant -- for a beautiful strikingly-colored butterfly, the Red-bordered Pixie (Melanis pixie, Riodinidae, the metalmark family) -- an atypical species that flies in overcast and even drizzly weather and may be found in the shade on sunny days.

The fruit is sweet. But what I like is that it appears to be a magnet for songbirds. They love the pods!

On the downside, the seeds will sprout everywhere!

I bought this fruit from some Mexican people at a farmers market north of Plant City. I found the fruit to have a texture and taste like dried coconut and raisins. Very good. Each piece of white fruit surrounded a hard black seed which germinated easily.

Then I spend a couple of years trying to find out what I had. It is indeed prickly and to be handled with care. But blackberries are worse. And if it fruits for me, I will be very happy with it. It is definitely easy to grow

Pithecellobium dulce is one of the most common trees of the Mexican highlands. Its Nahuatl (Aztec) name was cuauhm˘chitl (pronounced kwah-ooh-'mau-chittal), the "popcorn tree", cuahu(itl) meaning "tree", and m˘chitl, "popcorn". (The pre-Columbian Mexicans "invented" popcorn.) In fact, the white, sweet and edible flesh around its seeds strongly resembles popcorn, both in shape and in texture. Even today, the most common Mexican name of the tree is guam˙chil (pronounced gwah-ooh-'moo-chill), an obvious corruption of its Aztec name.

When ripe, the pods burst open, so it is very easy to pick the sweet flesh which is still a very popular snack among Mexican farmers, especially kids. In some places, it is also used in atoles (gruels) which, as always in Mexico, are sipped from a m... read more

It is not a pretty tree to landscape with and it is very thorny and spikey. It has a spreading habit with irregular brancehs. Leaves are deciduous but new leaves appear while the old ones are being shed. Flowers are small whitish-greenish color with often a sweet smell. The fruits or legumes are redish color and about 10-12" long. There are approximately 10 seeds in each pod. The pods pods are irregular and flat in shape and are spiraled. The fruit is sweet and have a chestnut sort of flavor. They are often used in making drinks. The flowers attract bees and it said to make a wonderful honey. The bark is very high in tannin and the tree also produces a gum similar to gum arabic.
