This showy perennial is usually unbranched but may exhibit some branching. The erect, 2-3 ft., stems produce lavender-blue, tubular flowers crowded together on the upper stem. Showy, bright blue flowers are in the axils of leafy bracts and form an elongated cluster on a leafy stem. Each flower is split into two lips - the upper lip has two segments and the lower lip has three.Great Blue Lobelia forms a flower spike covered in deep blue flowers from late summer to early fall. It can form colonies when happily sited in medium to wet soils in light shade, but is not overly aggressive. Combine Blue Lobelia with Cardinal Flower for a stunning color combo that will bring in the hummingbirds. Excellent for damp clay soil.

The Great Blue Lobelia, Lobelia siphilitica, is a perennial flower native to most of North America. It will grow 2-3′ tall in optimum conditions producing several stalks or spikes of dark blue/violet flowers. So, it is erect in its footprint, and doesn’t branch out. The blooms are quite showy, and are mainly pollinated by bees. I’ve found this plant in partially shaded meadows along the Appalachian Trail near my home. The soil/area didn’t seem that moist, but obviously this plant was happy there! Based on that, I’ve added some plants to our backyard micro-prairie. See how to grow your own micro prairie here==>>The most economical to get Blue Lobelia in your garden is to just grow it from seed. It is pretty easy to do so, and you can get blooms the first year if you are early enough. I’ve never actually seen this plant for sale in a garden center, so you might be forced to germinate them yourself. But, as I will show you that isn’t an issue. So, to start the plant in pots, just fill them with potting soil (I just use regular Miracle Grow potting soil) and moisten so it is fully damp. Then, sprinkle seed on top of the soil, and press in with your finger, but don’t bury it. These seeds need light to germinate, so it is important that they stay on top of the soil. Also, this seed is very tiny – like powder. So be careful. If you sneeze while doing this you could lose most of your seed!

How long does it take to get a flower when Blue Lobelia is grown from seed? Well that will depend on how early you start your seeds, and ultimately how early you transplant out into the garden. I’m in zone 6, and I usually get blooms on Blue Lobelia if I transplant by July. I also get blooms if I grow them in 4″x4″ pots. I’ve transplanted blooming Blue Lobelia flowers from pot into the garden as late as October. So, you should be able to get blooms the first year as long as you start early enough. That is just another benefit of this perennial.The process for saving Blue Lobelia seed is the same as its cousin, the Cardinal Flower. Let the seed pods dry out on the stalk until they are brown/dry before collecting them. If you collect the pods too early the seeds may not have developed fully, and therefore may not be viable to germinate. Store seed in zip-bags if truly dry, or keep in paper bag or envelope.
