These critters can be be very hard to id. The 'scientific name' for these and many similar things, at least as muttered cussing under the breath by professional botanist/ecologists, is "It's yet another DYC." (D***ed Yellow Composite....) There are many wild species, and they cross-pollinate readily. The variations are enormous. Even within a so-called 'species', they are highly variable. In terms of propagating them, if you are digging them out of the dry riverbed, try to space the plants out a bit. And then let them set seed. As long as they are relatively happy, you will have them naturalizing well.

From "Wild Orchids of Florida", Paul Martin Brown, it looks most like Habenaria quinquesta, Michaux's Orchis. It is also similar to H. distans but the book says that this species is rare and restricted to Collier county. Perhaps you can look them up on the orchidspecies web site and see which looks best to you. Meg

In eastern Mass. at least, the most common plant that meets the 'daisy' archetype (Jungian perhaps? It seems like kids know how to draw them without actually seeing one) -- fairly large flower, white petals, yellow center (I apologize to the botanists cringing at my inaccurate use of these terms for composites) -- is the oxeye daisy, a non-native. The easiest way to identify it is the depression in the center of the yellow (which is lacking from the flowers in the picture from Utah). Asters and fleabanes, while they also may have white petals and yellow centers, are generally too small to fit my concept of a daisy. My field guide's description of wild chamomile is consistent with the flowers and foliage in the photo. (Oxeye daisy leaves are much wider and lobed/serrated.) Other daisy-like flowers in my guide (albeit only an eastern U.S guide) are: sneezeweed yarrow, mayweed, feverfew, and scentless chamomile, all non-natives to this area. (Sorry, too lazy to put in latin names, but they are available upon request.) -- wd

Glandularia is the accepted, Verbena is synonym. I would think it's more commonly called Verbena. http://eol.org/pages/483330/names/synonyms http://www.theplantlist.org/tpl/record/kew-89978 http://www.ars-grin.gov/cgi-bin/npgs/html/taxon.pl?419694#syn
