I love this little plant with bright blue flowers that bloomed from June-October for me.... at that time I decided to bring it inside for the winter to see if it blooms some more. It is doing well, has stayed bright green and I plan to move it back outside in the spring. I left one plant out to see if it will self seed for me. I believe I winter sowed this one, but am going to try again this year to make sure.
