So it would seem that Bacopa myriophylloides is enjoying the conditions now and has treated me to just 2 single flowers this morning. A crisp pinky/white, but none the less very attractive. The stems are only about 15cm high at the moment so it's a small plant, but a happy one! We've got about 30 of these in stock at the moment, so I wonder when the others might flower - would be great if they all did!
