Now you will be able to collect seed from these plants after the flowers die back and produce them for you! You will be able to start all the plants you could want from them - you are rich! If the seeds develop before Julyish, you can have a Fall crop if started in a bright but cool setting ( in seed starting mix and potted). Then, when they have a few true leaves, you can plant them out. Often,where we live, they do better in Fall than spring due to the lack of pests. Just keep them well watered and remove any worms that show up for lunch on the leaves.
Good Luck.

It's time to plant the beautiful cabbage plant here in Northwest La. I plan to plant in an outdoor bed exposed to full sun. Will this plant survive our summer heat which reaches triple digit temperatures?
