Flowers of nicotiana obtusifolia are small and rather inconspicuous, due in part to their dull coloration; pale cream, or greenish yellow, borne in clusters at the top of the leafy, grey-green stems. Lower stem leaves have short stalks while those higher up are clasping, and narrower. The flower cluster has a few leaf-like bracts around the base, while individual flowers are attached via a light green, five-lobed calyx which, like the stems, bracts and leaves, has a covering of short white hairs.

The tubular corolla is about one inch long, and it opens to five lobes, bent back a little below the plane when fully mature. Lobes are blunt-pointed, about the same length as the corolla diameter. They have a lengthwise groove down the middle. Inside the corolla tube are five stamens attached near the base; they are unequal in height, and not exserted.
