Is Lobelia Self-Seeding
I know lobelia is considered an annual, but is it self-seeding? Or will I need to replace the plants every year? If it is self-seeding, when will it be "safe" to remove the dead growth?

Although not always typical, annual lobelia does occasionally have the propensity to self-seed under good growing conditions. To alleviate this, simply cut off the blooms once faded.
