Overwintering Survival of Milkweed Species

at Varying Elevations of Northern Arizona​

 

 

 

 

 

This 2016 to 2017 study, evaluated the overwintering success of various milkweeds in three Arizona elevation ranges: the mid-elevation range of 3,000-6,500 feet of the Verde Valley which includes, Camp Verde, Clarkdale, Rimrock, and Sedona, the Prescott Valley range of 4,800-6,200 feet, and the high-elevation range of 6,500-7,300 feet of Flagstaff. In the spring and summer of 2016, Citizen Scientists were selected based on their garden suitability and their location in these Arizona ranges. Every week for four months, the gardeners returned data sheets on the condition of their milkweeds. In spring 2017, these gardeners were asked about the condition of their species after the winter months. The Master gardeners recorded which species returned or did not return. Six gardeners participated in this data collection from Flagstaff, three participated from Verde Valley, and two participated from Prescott Valley. The information gathered will be serve as recommendations for growing milkweeds and help formulate testable alternative hypotheses for future projects.

 

 

Arizona Milkweed Species Planted in 2017

With Flowers 

June- September 2017

This 2017 study, evaluated the success of various milkweeds in three Arizona elevation ranges: the mid-elevation range of 3,000-6,500 feet of Verde Valley which includes, Camp Verde, Clarkdale, Rimrock, and Sedona, the Prescott Valley range of 4,800-6,200 feet, and the high-elevation range of 6,500-7,300 feet of Flagstaff. Citizen Scientists were selected based on their garden suitability and their location in these Arizona ranges. From June to September the gardeners returned data sheets on the condition of their milkweeds and if milkweeds produced flowers or seeds. In 2017, fourteen gardeners participated in this data collection from Flagstaff, eight participated from Verde Valley, and five participated from Prescott Valley.

 

The purpose of this aspect of project was to determine which species flowered or produced seeds within the first year of being planted. Flowering and seed production is a sign that the plant is healthy. The Asclepias species tested were A. angustifolia, A asperula, A. latifolia, A. linaria, A subverticillata, A. tuberosa, A. speciosa, and A. fascicularis.
