Hi James,

I have irises doing well under black walnut, and lots of daylilies 
(Hemerocallis) in beds under Black Walnut. Try also the hardy Gladiolus 
like byzantinus, illyricus, italicus, and imbricatus.

I also suggest trying Lycoris as preached by Jim Waddick! I don't have any 
under walnuts, however, so I don't know if they are affected by the 
secreted alkaloids.

There is a huge long list of things you can try: Arisaema, Anemone, 
Anemonella thalictroides; Brodiaea californica; Claytonia virginica; 
Corydalis solida; Dicentra canadensis, D. cucullaria, and D. spectabilis; 
Dichelostemma congestum; Erythronium of all sorts; Fritillaria meleagris; 
Galanthus elwesii, nivalis, and woronowii; countless types of Narcissus (I 
have some in a bed under a black walnut); Polygonatum biflorum, P. odoratum 
variegatum; Sternbergia lutea; Triteleia ixiodes scabra, laxa 'Queen 
Fabiola', bridgesii; Trillium species of all sorts.

I would not bother with tulips or Dutch hyacinths.
