Please add this plant to Plantfiles, it's very common yet not listed.
Please add Tropical Milkweed Asclepias curassavica to Plantf
It's already there--both the straight species as well as multiple cultivars. Not sure why it didn't come up when you looked for it. http://davesgarden.com/guides/pf/adv_search.php?searcher%5Bcommon%5D=&searcher%5Bfamily%5D=&searcher%5Bgenus%5D=asclepias&searcher%5Bspecies%5D=curassavica&searcher%5Bcultivar%5D=&searcher%5Bhybridizer%5D=&searcher%5Bgrex%5D=&search_prefs%5Bblank_cultivar%5D=&search_prefs%5Bsort_by%5D=rating&images_prefs=both&Search=Search
As a side note--if you ever do run across a plant that really isn't in Plant Files, it's a database that relies on all of us to add plants & info so the best thing to do is enter it yourself. If you're not sure how to do that, people can provide advice along the way to help you through the process.
That's strange it didn't show, I was using my i phone so that might have been why.
Maybe you accidentally mis-spelled the name or something in the search--easy enough to do with those little tiny touch screen keyboards! :) (or maybe your iPhone "corrected" your spelling for you in a way that Plant Files wouldn't recognize what you were trying to search for)
