trailing lobelia

Question

Will this plant self seed and come up again next year?

Answer 1

It will depend on your soil and winter conditions. Lobelias are considered annuals, meaning they aren't "supposed" to come back each year, but I've had several annual plants that did self-seed when the conditions were exactly right. I wouldn't count on it, though, since Lobelia seeds are so tiny...they probably wouldn't survive a harsh winter climate. Here's an article that provides some tips on Lobelia care:

Answer 2

Both annual and perennial Lobelia will self sow if the conditions are right.
