About plant names...

Bladderpod spiderflowers—what a great name!—are North American natives.

Identification: This shrub has a scent variously described as ”unusual,” “ill-scented,” or “pungent smelling.” It is remarkably rounded or oval in shape, up to 8' (2.4 m) around, evergreen, with inconspicuous thin gray-green leaves ½-1¾" (1.5-4.5 cm) long, usually in groups of three. Attractive bright yellow flowers with long stamens appear everywhere on the shrub. The fruits (the “bladderpods”) are variably shaped, resembling inflated paper lanterns. They are 1-1½" (3-4 cm) long, approximately oval, and smooth.
