I'm growing this from seed for the first time, and I've seen these plants in their mature state.....they have long-legged stems with bracts of blue flowers all the way down the stems. They are very similar to the lotus vine in growth habit. My seedlings are now about 2" tall and I can see about 3 sets of leaves now, some with a 4th set. I have them under growlights for now, but I believe that as with many annuals, these will need to be pinched back in order to get more of these stems. Can anyone advise me on this? Thank you.
