Wild bergamot is a showy plant in the mint family that often occurs in dense stands in Jackson Park. Flowerheads/clusters 1-3" in diameter arise at the apex of flower stems that arise from leaf axils. Blooming begins in the center of the cluster and moves progressively toward the periphery, with the arching flowers pointing in all directions. Flowers are tubular (they remind me of baroque trumpets with embellished bells), about 1" long. They have a short green tubular calyx; a lavender or pink corolla (other mints are white, red, or purple); an awning-like upper lip beneath which protrude two stamens with brownish-purple anthers and the single style (with an unevenly bifurcated tip) significantly longer than the stamens. The 1/2" wide lower lip offers a surface where the pollinators land. The lower lip has three small lobes at its tip. Seeds develop within the persistant calyx. The very similar bee balm (Monarda didyma) has scarlet flowers. Wild bergamot is widely used as a component of herbal teas.

Spotted beebalm (aka, spotted horsemint) is a curious-looking plant 1-3' tall; it reminds me of the top of a pineapple with spotted coffee-with-cream colored flowers under the arching leaves. There are whorls of leaf-like bracts below the flowers that are white to deep pink or lavender, shorter and broader than the leaves, and invariably have smooth margins. The flowers are 3/4-1" long with a tubular calyx with five triangular teeth at the base and a cream to yellow tubular corolla with purple spots. The corolla consists of an upper lip covered with long, fine hairs on the exterior and a lower lip with three small lobes on its tip. Nestled under and paralleling the upper lip are two stamens and a style; the brown anthers and bifurcated stigma protrude beyond the tip of the lip. The fruit consists of four nutlets hidden within the persistant calyx. Spotted beebalm is unlikely to be confused with any other wildflower in Jackson Park.
