Hi Sherry,
The default "flowering shrub package" that opens up in the drop down menu on the right does have those elevation requirements, but many of the other plant packages [like the native pollinator plants package, described as "Package contains 14 New Mexico Forestiera, 14 Apache Plume, 14 Skunkbush sumac, and 7 Rocky Mountain Penstemon. For specific species characteristics see individual seedling descriptions. This package plants that are preferred by our native pollinators] have lower elevation requirements. There are over 70 different species offered, including desert willow, so it looks like there's something for everyone in our state! :)
Thanks, Heather
