Growing Lobelia on Martha's Vineyard

Lobelia cardinalis, the cardinal flower, is a native perennial that thrives in the moist, seasonally wet conditions found along the margins of Martha's Vineyard's numerous freshwater ponds and in the rain-retaining low areas of properties throughout the island. Its intensely red flower spikes in midsummer are among the most vivid colors available in the island's native plant palette, attracting ruby-throated hummingbirds with predictable consistency during their late-summer southbound migration. It tolerates the island's naturally acidic soils well and requires minimal supplemental fertilization when sited in organically rich, moisture-retentive positions.

Deer largely avoid it due to its alkaloid content, a significant practical advantage. Estate Care professionals value it as a signature native planting in pond-edge and rain garden designs, where it provides both ecological function and exceptional seasonal drama.
