Thank you Jim Jones---you give me hope for A. ligtu, and to Jim McKenney for the Latinate pune clarification and your continuing information which helps me grow stuff that I shouldn't even try here in the Chicago area. Colder than you, but it's helpful information. I'll off the top of my head mention stuff that is invasive, and nearly impossible to rid of (the geophytic ones). An onion, native which never blooms and probably is the one that Chicago is named for. Small and spreads like dandelions. Scilla siberica, invasive and nice for a few weeks in early May, but nearly immune to weedkillers that aren't Roundup. The not nasty but otherwise reliable class . Lily of the valley (Will send a hunk of about 36 square inches to anybody who asks. If you can't grow it it's probably beause you coddle it and water it or something.) Not a bulb but maybe fits into a geophyte class .? Mertensia virginica. Every year, it's there with the Convalarria Reliable "if you don't mess with them too much" class All of the larger Narcissus hybrids; and daylilies; and ANY tulip I've tried, species or hybrid; Arisaema triphyllum, any form; . Arisaemas amurense, sikokianum and the Sikotak hybrid from Eco-Gardens in Georgia ; Codonopsis lanceolata , good for 4 years running now at the base of a corkscrew willow. Yucca (of gardens about 6 feet high) in a spot that floods vernally for weeks at a time and has its seeds eaten regularly by some kind of moth larva. . A not definitively identified variegated Polygonatum from a friend in Wisconsin, but the one that has a green opening to its bell and pictured on Dogpile Images., spreads nicely and hs beatifiul pink sprouts when they first show out of the ground. The trilliums luteum, and recurvatum are reliable and stay where I put them. . Haven't tried the others, but may do so. Sanguinaria canadensis seems to do OK, but I'm losing one for as yet unknown reasons, but I'm guessing that it's gettign trampled by mating squirrels as it's been in their path for a few years. Will move it to save it. . Most of the hybrid lilies do well if I can keep the squirrel away from them. They kill them by climbing them and break off their stalks about the time that they're beginning to look climbable., i.e., about a foot,. Does Bleeding Heart count as a geophyte? Both the newer smaller hybrid and the old species are reliable for me as are Tricyrtises. Peonies are sort of a standby but don't like to have wet feet for more than a week. I think this has been and may continue to be a good thread. We need to know what grows for us in various regions and soil and climate conditions. I deliberately am trying grossly out-of-range things and having a few moderate successes along with Jim Waddick, Jim Shields, Jim McKenney and probably a few experimenters. Cheers, Everyone .
