Notes

Flora of North America informally describes three varieties of S. pungens (pungens, longispicatus, & badius), all appearing to be native to the U.S. More work needs to be done on the exact ranges of each species. Variety longispicatus is native to the Fort Collins area.


This species has a moderate salt tolerance. Plant widths are best estimates.
