Plants are organized alphabetically by genus and species. Hover over a photo series to control the images.
Dogbane flowers are pink or white, depending on the species, and occur in clusters at the top of the plant. In my experience they don't all open at once. In any case, you won't see the flowers during much of the growing season. Instead, look for the maroon twigs and long, pointed, smooth-edged leaves. You may see dogbane leaf beetles munching on those leaves; you can see photos of the beetles on this page. In the fall look for pairs of long, skinny seed capsules. Before New Mexico's Native Americans had cotton, they used fibers from dogbane stems for weaving their finest textiles.
Spider Milkweed, Antelope Horns (Asclepias asperula)
This is mostly a plant of the southern Plains and Southwest. Look for balls of flowers above skinny pointed leaves. A close look shows that the flowers include both very light green and purple, but in strong sunlight the flowers look "whitish."
Broadleaf Milkweed (Asclepias latifolia)
In New Mexico's high desert, Broadleaf Milkweed plants stick out like a sore thumb. The flowers can turn yellowish as they age.
Showy Milkweed (Asclepias speciosa)
In one picture the ball of pink flowers is less crowded, making it easier to see the folded-back "skirt" typical of milkweed.
Horsetail Milkweed, Yerba lechosa (Asclepias subverticillata)
This is a very common Albuquerque "weed." Look for skinny, upward-pointing leaves and clusters of small white flowers. Each of the flowers has a "skirt." One photo of the fruit includes oleander aphids; you can see more of them on a separate page.
Butterfly Milkweed (Asclepias tuberosa)
To identify this one, look for a cluster of egg-yolk-yellow to orange flowers, each of which has a downward-turned "skirt." The clusters occur on top of a symmetrical plant (which can occur in bunches). I included one photo where the the flowers have wilted because it shows the the stalk and leaves.
Climbing Milkweed (Funastrum cynanchoides)
This vine insinuates itself among other plants. I have found it at the mouths of Embudito and Bear Canyons, at the edge of Albuquerque. The SEINET plant list for Bernalillo doesn't include Funastrum, so I won't blame you if you're dubious about my ID.
