PALE SPIKED LOBELIA
Open areas, usually at least seasonally wet, including meadows, fields, shores, calcareous flats and rocky openings, edges of swamps and marshes, oak savanna, prairies. The only collections purporting to have come from Keweenaw Co. were made by O. A. Farwell in 1885 and 1886.
Depauperate plants might be confused with L. kalmii, especially since the two may grow together, but the latter has relatively shorter calyx lobes, bracteoles near the middle of the pedicel, and linear glabrous cauline leaves. In L. spicata, even small leaves are elliptic and finely pubescent.
The corolla is often rather pale blue, sometimes nearly or quite white. The inflorescence is unbranched, a slender spike-like raceme. Lobelia inflata, except in small plants, is branched. Both this species and L. inflata vary greatly in size and other characters.
