Question also is - what hemerocallis is this? Given the combination of old homestead + bright yellow, I would guess at H. lilio-asphodelis, aka H. flava. RHS Dictionary of Plants describes it as "Scapes closely branched above, weak, ascending, taller than foliage . . ." Which suggests that a goodly number of flower buds might produce the nodding effect. This is a charming species with fragrant flowers. I collected mine years ago from an abandoned homestead along Rte 7 in Connecticut. The case of poison ivy was an acceptable "cost" as I like the species. Two early ones, H. middendorffii and H. dumortieri are now in bud. Judy in well watered New Jersey where we received 4 inches of rain between May 1 - 7
