Lobelia x gerardii "Vedrariensis"
Lobelia x gerardii "Vedrariensis" is one of the most beautiful and satisfying plants that I grow, and that's the truth. I have been more excited about this plant than anything else new I've grown lately, and it's a keeper if there ever was one. The large blooms are deep, true purple on plants from two to three feet tall. This exquisite perennial Lobelia prefers sun with some shade mixed in and thrives in moist soil. In fact, I have even seen it planted in pots submerged in water. Now that's a good idea. Zones (5)? 6-8. Quarts. (Photo by Magnus Manske, Wiki Commons).
