My 2 cents worth. I only grow some typical yellow flowered probably E bungei ( or is it stenophyllus)* on a slope where they have multiplied slowly over the years and put on a reliable show each spring. They take out extremes of hot and cold well and are quite dry in summer. I do want to relate the best Eremurus I have ever seen which was along the highway near Dodge City Kansas. Here a variety of colors was nearing 6 ft in height and self seeding wildly in a large patch as road side 'seed'. I had to stop the car and talk to the owners who professed no special care which essentially means even hotter and drier summers than I get here. At least some of the species are native to similar steppe environments in Central Asia. Not necessarily good drainage, but a hot dry dormant period in summer. I suspect that many of these plant experience wet springs even standing water briefly, but these are not plants of wet environments. Best Jim W. * Brent and Becky list some of their special Spring Valley hybrids which I keep meaning to order, but keep procrastinating. Has anyone tried this mix yet? http://brentandbeckysbulbs.com/spring/productview/… They look great. -- Dr. James W. Waddick 8871 NW Brostrom Rd.
