While we were in the Phoenix area we visited the Boyce Thompson Arboretum near Superior, Arizona.  It is a large area with almost 100 years of plantings.   We wandered through the gardens for a few hours and took many photos, only a few of which are featured here.

Near the entrance was a Texas Mountain Laurel (Dermatophyllum secundiflorum) in full bloom.

In the succulents garden this Jade plant was blooming.

Some fruit trees were also setting flowers in early March, including this plum tree.

One of our favorites is the western spiderwort, which we have encountered in the canyons in Utah.

Extensive cactus plantings were found on the grounds, but we enjoyed this planting of barrel cacti.

The gardens are managed by a Society and much of the site was in fine order, but there was limited signage for plant ID, including this one:

Tree Germander (Teucrium fruticans) is a shrubby evergreen flowering plant in the mint family. 

We have shared only a few images here.   Boyce Thompson Arboretum is a fine destination for anyone with an appreciation of plants of the Southwest.
