Panayoti, Mirabilis rotundifolia looks awesome! Judging from the masses blooming in the gardens at DBG, it looks to be a good garden plant too! Difficult to find photos of this rare Colorado endemic, but I did find a couple resources with photos.  I cite a couple of PDF files describing this species and other plant species being watched; and in fair use, for those who might have slower connections and who might have difficulty downloading multimegabyte PDF files, I have posted a couple screen captures from one of those documents.

Mirabilis rotundifolia (Oxybaphus rotundifolius), drawing and two low quality photos.It seems both names are used interchangeably, although Mirabilis gets cited more often that Oxybaphus, so I'll stick with Mirabilis.In this one the foliage looks very round, although the leaf shape is said to be variable in the species.http://www.cnhp.colostate.edu/download/projects/rareplants/pdfs/23147.pdf

Rare Plant Surveys on Fort Carson 2006-2007, Colorado State Univ., 70 pages, 5.5 MB PDF, or click on screen capture images below.If you like maps, this PDF document has colorful visually interesting ones; detailed distribution map of M. rotundifolia on page 63.  Some good photos of other plant taxa too.http://www.cnhp.colostate.edu/download/documents/2007/FtCarson_FINAL1221...

Photo of M. rotundifolia seedlings; site is very slow to display non-optimized images, so again in fair use, here is a screen capture to click on in lieu of the url:http://www.centerforplantconservation.org/collection/CPC_ProfileImage.as...

Mirabilis expansa (Mauka) is one of the rarest root vegetables in the world, only discovered in the 1960s, and discovered being cultivated in Peru as late as 1987 and only known from 3 remote but spread areas. One of the Lost Crops of the Incas (see http://www.nap.edu/openbook.php?record_id=1398&page=75). A friend in Belgium is probably the first to trial this plant in Europe. I visited him a couple of years ago. Although not that exciting to look at, here it is:

Very interesting, Stephen! I guess it should still have showy flowers at some point? I wonder if any of the other species are edible?
