Pollinator Plants of the Desert Southwest

Pollinator Plants of the Desert Southwest

The Desert Southwest harbors at least 41 of the 76 milkweed (Asclepias spp.) species known to exist in the lower 48 states. The species richness of milkweeds in this region is influenced by the tremendous diversity and range of vegetation types, soils, topography, climate, and the exposure of unusual rock types that occur over more than a 9,000 foot elevation range.

The nectar of milkweed flowers is attractive to dozens of insects including bees, wasps, butterflies, moths, and hummingbirds. The bees that milkweed flowers attract to agricultural landscapes are important for pollinating a wide variety of vegetable forage and fruit crops.

Conservation You Can Taste:   Saving Forgotten Fruits of the Borderlands

Conservation You Can Taste: Saving Forgotten Fruits of the Borderlands

Three hundred years ago, Spanish missionaries introduced a suite of arid-adapted fruit and herb varieties to the Sonoran Desert region, many of which have barely survived to this day.

These desert-adapted, heirloom fruits enriched the diets and diversified the farms indigenous and immigrants alike, but fell out of availability and culinary fashion. Today, these forgotten fruits are once again needed because they are tolerant of heat, drought and even alkaline conditions.

Stalking Oregano in the Wilds of Mexico

Stalking Oregano in the Wilds of Mexico

Few American gourmands realize that most of the oregano they use to spice up sauces, meats, salads and vinegars—whether it be Greek or Mexican in origin—is hand-harvested from wild habitats. Although many varieties of oregano can be cultivated and irrigated as perennial crops, their aromatic oils become diluted as their leaves enlarge under well-watered conditions.

These same aromatic oils—called thymol and carvacol— become more concentrated, intensely flavorful and pungently memorable when the crisp, dry diminutive leaves of oreganos are harvested from deserts or from salt-sprayed coastal landscapes.
