History
The gardens were established in the mid 1920s as the
Southwest Arboretum by engineer and philanthropist William Boyce Thompson, situated next to a narrow riparian corridor along
Queen Creek, surrounded by arid lands typical of the habitats of most of the plants in the collection. Today, the site is managed jointly with two partners, University of Arizona who assist with research and conservation, and Arizona State Parks who manage the public facilities. Thompson, the founder, resided for a few years in the
Picketpost House, just east of the gardens; he died in 1930, deprived by illness of his anticipated lengthy retirement in this peaceful location.
Overview
Boyce Thompson Arboretum is easily reached from Highway 60, near the east end of its divided, freeway section. Fees (2013) are $9 for adults, $4.50 for children, free for the under fives. Entry is past a bookstore, gift shop and plant sale area; the main loop, all paved but not all wheelchair accessible, starts just beyond, and is approximately half through desert habitats and half through the wooded environment close to the creek; this latter part has a great variety of trees including palms and eucalyptus. Drinking water is available by the entrance but not elsewhere. A selection of more delicate plants, mostly cacti and other succulents (largely from South America and Latin America) are housed in greenhouses, though all other specimens are outside. Plants are well labeled, and many species occur in multiple locations. The northwest part of the loop runs close to the highway, within range of traffic noise, but the remainder is quiet.
Plants
Small collections include rock plants near the entrance, roses just beyond, herbs along the south part of the loop, and aloes nearby, while major sections are the following:
Australian Desert; trees, bushes and other plants from Australasia.
Cactus and Succulent Garden; over 300 varieties of cacti and other succulents grow here, though still by no means all species from the Southwest. One type discovered at this location and named after the benefactor is
echinocereus boyce-thompsonii. Central America is well represented, plus Baja California, where cacti include the cardon (pachycereus pringlei) which is the world's largest cactus, growing taller even than the giant saguaro.
Chihuahuan Desert; desert plants of south New Mexico, west Texas and north central Mexico, viewed by the 0.3 mile Curandero Trail.
Sonoran Desert; plants native to south and central Arizona, and northwest Mexico, also viewed by a 0.3 loop trail.
South American Desert; a smaller group of plants from Argentina, Bolivia and Paraguay.
Taylor Legume Garden; this small enclosure houses flowering plants from the pea family (fabaceae), many of which are edible.
