Again, we have a plant of interest! Last year I had the adventure of trying to start some Rosemary plants from seed. (See The Rosemary Story earlier in this blog.) We had a difficult time identifying the plants that came up, which we knew weren't Rosemary. This year I planted some Forget Me Not flower seed. The plant shown here looked like the Forget Me Not when it was transplanted into this hanging pot. Then it started to grow so fast and now reaches the top of the greenhouse. And look at that flower! So different! Definitely not a Forget Me Not! We eventually discovered that last year's mystery plant was Lemon Balm, but we are truly mystified by this one. Can you help?
