Question
can my potted blue lobelia be an indoor plant in the winter?

Answer
Valerie,
No, blue lobelia is prone to whitefly and other insects indoors so doesn't do well as a houseplant. In fact, if you live where the summers get hot it may not do well as an outdoor annual either... lobelia only blooms all summer in cool climates like Alaska. So enjoy it while it's beautiful!
all the best,
C.L.
