# Zizotes Milkweed (*asclepias oenotheroides*) Zizotes Milkweed (Asclepias oenotheroides) is a resilient, low-growing perennial plant native to the arid and semi-arid regions of the southwestern United States and Mexico. Unlike many of its taller, upright milkweed relatives, this species often sprawls close to the ground, adapting exceptionally well to sandy, gravelly, or heavily disturbed soils. Known historically in folk medicine, this tough plant is a critical contributor to local biodiversity, drawing in a wide variety of native bees, wasps, and butterflies with its nutrient-rich nectar. Beyond its role as a nectar source, Zizotes Milkweed is an indispensable host plant for monarch and queen butterflies. Caterpillars of these species feed on its foliage, consuming toxins that protect them from predators. Its drought tolerance and low-profile growth make it an increasingly popular choice for native xeriscaping and dedicated pollinator conservation gardens. - **Category:** [Plants](https://www.snappit.app/explore/categories/plant) - **Rarity:** Common - **Danger:** 1/5 · Very low - **Snaps:** 1 - **Habitat:** Found in dry, open environments such as sandy prairies, pastures, roadsides, and disturbed fields. ![Zizotes Milkweed](https://inaturalist-open-data.s3.amazonaws.com/photos/9631793/medium.jpg) Photo: Alex Abair, CC BY 4.0 · [iNaturalist](https://www.inaturalist.org/photos/9631793) ## Appearance Zizotes Milkweed typically grows as a sprawling or low-ascending herb, reaching heights of 10 to 45 centimeters. It features opposite, broad, lance-shaped leaves with highly characteristic wavy or crinkled margins. The flowers are uniquely clustered in dense, spherical umbels that arise directly from the leaf axils along the sides of the stem, rather than solely at the top. These blooms are a pale greenish-yellow or cream color, featuring elongated, crown-like hoods that lack the prominent internal horns common to other milkweed species. ## Taxonomy - **Kingdom:** Plantae - **Phylum:** Tracheophyta - **Class:** Magnoliopsida - **Order:** Gentianales - **Family:** Apocynaceae - **Genus:** Asclepias ## Interesting facts - The cardiac glycosides sequestered by monarch caterpillars from this plant remain in their bodies through metamorphosis, keeping the adult butterflies toxic to birds. - The name 'Zizotes' is derived from a Spanish adaptation of a Nahuatl word referring to skin sores, as the plant's milky sap was traditionally used in folk remedies. - Unlike most milkweeds that only produce flowers at the very top of their stems, Zizotes Milkweed blooms in side-clusters all the way up the plant. ## Special abilities - **Chemical Defense:** Produces a milky white sap rich in toxic cardiac glycosides (cardenolides) that deters most herbivores from eating its foliage. - **Drought-Resistant Taproot:** Features a deep, fleshy taproot that stores moisture and energy, allowing the plant to survive prolonged dry spells and regenerate after mowing or grazing. - **Axillary Flowering:** Develops flower clusters at multiple leaf joints along the stem, maximizing reproductive potential and staying accessible to low-flying pollinators. ## Measurements & details - **Length:** 10-45 cm - **Lifespan:** 3-10 years ## Diet & Feeding As a photoautotroph, this plant manufactures its own energy using sunlight, water, and carbon dioxide through photosynthesis, while absorbing essential minerals from the soil. - **Primary Foods:** Sunlight, Water, Carbon dioxide, Soil nutrients ## Ecological connections - **Host plant:** [Monarch Butterfly](https://www.snappit.app/explore/monarch-butterfly) (*Danaus plexippus*) — Serves as a critical larval host plant and source of defensive chemical compounds. - **Host plant:** Queen Butterfly (*Danaus gilippus*) — Acts as a primary larval host plant for caterpillars to feed and grow. - **Eaten by:** [Large Milkweed Bug](https://www.snappit.app/explore/large-milkweed-bug) (*Oncopeltus fasciatus*) — Feeds on the seeds, sap, and pods, concentrating the plant's toxins for its own defense. ## Safety **Danger:** 1/5 · Very low No special safety notes yet. ## Frequently Asked Questions ### How to identify Zizotes Milkweed? Start with the whole plant, then compare leaf arrangement, leaf edges, stems and any flowers or fruit. Opposite leaves grow in pairs; alternate leaves come one at a time along the stem. These details tell you far more together than a single green leaf does. Plant Identifier: upload a photo and compare the visible details. ### How long is Zizotes Milkweed? 10-45 cm ### How long does Zizotes Milkweed live? 3-10 years ### What does Zizotes Milkweed eat? As a photoautotroph, this plant manufactures its own energy using sunlight, water, and carbon dioxide through photosynthesis, while absorbing essential minerals from the soil. ### Where is Zizotes Milkweed usually found? Found in dry, open environments such as sandy prairies, pastures, roadsides, and disturbed fields. ## Where to spot - [Fort Brown](https://www.snappit.app/guides/places/fort-brown) — US · Historic Site ## More Plants - [white snakeroot](https://www.snappit.app/explore/white-snakeroot) (*Ageratina altissima*) - [tree-of-heaven](https://www.snappit.app/explore/tree-of-heaven) (*Ailanthus altissima*) - [western sword fern](https://www.snappit.app/explore/western-sword-fern) (*Polystichum munitum*) - [common milkweed](https://www.snappit.app/explore/common-milkweed) (*Asclepias syriaca*) --- Source: [Zizotes Milkweed: Facts & Places to See — Snappit](https://www.snappit.app/explore/zizotes-milkweed)
