Lobelia siphilitica (Great Blue Lobelia)
Lobelia siphilitica offers a deep-hued counterpoint to the yellows of late summer. It can form colonies of richly-flowered spikes, 2-3’ ft. tall, in medium to wet soils, especially with a little shade.

Seeds / Packet: 1,000
Seeds / Ounce: 500,000

Lobelia species are susceptible to frost-heaving when planted in the fall, so we ship the bare roots in Spring only.

Potted plants come in a tray of 38 plants and ship late May through late July.  If you prefer to mix and match up to 4 species in a tray (at no additional charge), click here for the 'Mix and Match' tray option.
