Plant Milkweed and Nectar Flowers for Monarchs

From: Monarch Joint Venture (www.monarchjointventure.org)

Monarchs cannot survive without milkweed. Monarch caterpillars need milkweed plants (Asclepias spp.) to grow and develop, and female monarch butterflies monarchs2only lay their eggs on milkweed.  Much of our milkweed has been lost from our landscape due to changing land management practices such as urban and suburban development and agricultural intensification.  Historically milkweed has been viewed as a crop weed or a threat to livestock and has been eradicated.

Please plant milkweed native to your area and a wide variety of high quality nectar bearing flower species to support monarch populations, and their incredible migration!  Adult monarchs follow nectar corridors, a series of habitat patches of plants that flower at appropriate times during the spring and fall migrations.  They provide stopping off points for the butterflies to feed and stock up during their long migrations.

Planting milkweed is a great way to help other pollinators too, as milkweed provides abundant, high-quality nectar or shelter for a diverse array of other insects, including nectar-seeking bees, flies, and butterflies, and such specialist herbivores as seed bugs, longhorn beetles, and leaf beetles. Native milkweeds are clearly worthy of wider adoption.  More than a hundred species of milkweeds (Asclepias) are native to North America and they can be found in deserts, plains, valleys, foothills, open woods, and wetlands. Milkweeds typically grow in disturbed environments including agricultural areas, livestock pastures, ditches, and roadsides; indeed, in some areas, these marginal habitats are the only places where milkweed is regularly seen.

Milkweed Regions

There are many native milkweed species in MonarchZones
each of the six “Milkweed Regions” shown on this map. The species below are known
to be used by monarchs, and are easy to
establish.

To Purchase Seeds:

Western Region:    
Asclepias fascicularis Mexican Whorled Milkweed Dry climates and plains except CO, UT, AZ, NM
Asclepias speciosa Showy Milkweed Savannahs and Prairies
California Region:    
Asclepias fascicularis Mexican Whorled Milkweed (Narrow-leaf) Dry climates and plains except CO, UT, AZ, NM
Asclepias speciosa Showy Milkweed Savannahs and Prairies
Asclepias erosa Desert Milkweed Desert regions
Asclepias californica California Milkweed Grassy areas
Asclepias cordifolia Heartleaf Milkweed Rocky slopes
Asclepias Vestita Woolly Milkweed Dry deserts and plains
Asclepias eriocarpa Woolly Pod Milkweed Clay soils and dry areas
Arizona Region:

 

   
Asclepias tuberosa Butterfly Weed Well drained soils
Asclepias asperula Antelopehorn Milkweed Desert and sandy areas.
Asclepias subulata Rush Milkweed Desert areas.
Asclepias angustifolia Arizona Milkweed Riparian areas and canyons
Southeast Region:    
Asclepias tuberosa Butterfly Weed Well drained soils
Asclepias verticillata Whorled Milkweed Prairies and open areas.
Asclepias variegata White Milkweed Prairies and open areas.
Asclepias perennis Aquatic Milkweed Hydrated soils.
Asclepias humistrata Sandhill/Pinewoods Milkweed For use in some regions of FL.

Dry sandy areas and soils.

NE Region:    
Asclepias syriaca Common Milkweed Well drained soils.
Asclepias incarnata Swamp Milkweed Damp, marshy areas.
Asclepias tuberosa Butterfly Weed Well drained soils
Asclepias verticillata Whorled Milkweed Prairies and open areas.
Asclepias exaltata Poke Milkweed Woodland areas (except in

NE, KS, MO, ND & SD).

South Central Region:    
Asclepias viridis Green Antelopehorn Milkweed Dry areas and prairies.
Asclepias asperula Antelopehorn Milkweed Desert and sandy areas.
Asclepias oenotheroides Zizotes Milkweed Sandy/rocky prairies and fields.
Note:  Be careful to not purchase or plant tropical milkweed, Asclepias curassavica,  if you are in a temperate region.  These plants are becoming naturalized and are suspected in ‘luring’ overwintering monarchs into breaking their dormancy and becoming reproductive which can also spread parasites endangering the population further.
