Blue Lobelia 

Blue Lobelia is a herbaceous perennial plant with its beautiful, deep blue flowers is just the thing for a rain garden, an herbaceous border, a woodland garden or as naturalized colonies beside a brook or a stream. Its scientific name is Lobelia siphilitica in honor of the botanist Matthias de l'Obel. It’s also called the blue cardinal flower or the great lobelia.  

The blue lobelia is native to the eastern part of North America and does best in hardiness zones 4 to 9.

It grows in clumps between 2 and 3 feet tall and has a 1 to 1.5-foot spread. Its blooms range from light to deep, Prussian blue. The flowers are tubular with two lips, with three lobes on the lower lip and two lobes on the upper lip. They are crowded near the top of an unbranched stalk and appear in late summer and even into early fall. The leaves are light green, lance-shaped, with fine teeth. They grow to about 5 inches in length. 

 The plant is just right for areas of the property whose drainage is less than ideal, for it loves rich, wet soil that’s full of humus. It thrives in both full sun, especially in the northern part of its range, and part shade. The plant doesn’t need much maintenance and self-seeds to form colonies, but it should be divided in the spring. The blue lobelia has no serious problems with disease or pests and is deer resistant.
