Some other yellow-flowered geophytes of note include: Arisaema flavum (light cadmium yellow) Arum creticum (spring-butter yellow) Bongardia chrysogonum (cream, yellow and gold) Corydalis schanginii subsp. ainae (white tipped bright gold with a drop of garnet) Many, many Crocus spp. I disagree with my dear friend Jim Waddick on their blahness (it's not his fault; he also likes bananas) and would specially recommend C. vitellinus (the name means eggyolk-yellow) as a tough beauty that multiplies fast enough to be relatively inexpensive. One could paint swathes with it. Disporum flavum (buttercup yellow) Erythronium americanum (medium cadmium yellow) E. grandiflorum (buttercup yellow; but many find it hard to keep) Fritillaria aurea (cadmium yellow) F. carica (greenish yellow) F. pallidiflora (mimosa yellow) F. pudica (cadmium yellow to greenish yellow, depending on the population) Iris bucharica (OK, it's yellow and white, but presents as an eye-smack of cadmium yellow) I. innominata (warm medium cadmium yellow) I. narbutii (dark gold) I. orchioides (mimosa and butter yellows) Lilium parryi (spring-butter yellow) L. canadense (moving into apricot) L. columbianum (gold) Sisyrinchium californicum (buttercup yellow) Tulipa -- I think these have been mentioned but let me recommend T. batalinii, a lovely pale lemon yellow. Uvularia grandiflora (sunshine tinged with green) Pictures of most of these are available on the net. Most are also pictured in the Bulbs section of my website.
