Seed of the Week: Angel’s Trumpets

Our mystery seeds from last week were from a plant commonly called angel’s trumpets, Brugmansia sp.


These large shrubs or small trees are originally from South America, although I admit that I have only seen them growing in greenhouses.

Brugmansia are called angel’s trumpets because of their extraordinarily large, hanging trumpet-shaped flowers. Plant breeding enthusiasts have developed beautiful hybrids and cultivars with flowers of many colors and shapes.

A relative of datura, all parts of these plants are toxic.

Seed of the Week: Velvet and Chilean Mesquite

Kathy recognized our mystery seeds from last week were from a mesquite tree, Prosopis sp.

Several types of mesquite trees grow in Arizona. We’ve already covered the screwbean mesquite and the honey mesquite in previous posts. Today we’re going to take a look at the native velvet mesquite, Prosopis velutina, and the Chilean mesquite, Prosopis chilensis. We are covering them at the same time because, although there are differences between the two species, they hybridize and the exact parentage of any one tree may be difficult to figure out.

In nature, velvet mesquites grow densely along desert rivers, forming what are called mesquite bosques.

Once pollinated, the seed pods begin to form.

Once the pods and cases are removed, the seeds are typical brown, shiny legumes.

The pods are consumed by a number of different animals, including coyotes. People also harvest the pods and grind them into a sweet flour for baking. The Desert Harvesters website is full of information about gathering the pods and processing mesquite flour, as well as information about the different species of mesquite.

Have you ever eaten foods made from mesquite flour? What is your favorite recipe?
