Inflorescence - Terminal and axillary racemes, with at least 20 flowers but usually many more.

Flowers - Perianth to +/- 3cm long. Corolla white, tubular, with five lobes - two on upper portion, three below.

Flowering - August - October.

Habitat - Moist to wet soils.

Origin - Native to U.S.

Other info. - This plant appears to grow taller than typical L. siphilitica with blue-purple flowers. It is quite striking and I was pleased to find it growing wild at the zoo (just this one plant), since it is uncommon in this state. This is the only time I have seen this plant.
Don't confuse this plant with L. spicata which has much smaller flowers and is a generally smaller plant.
