My husband has built me a raised pond in my new garden. It is not yet finished, but being very impatient, I ordered and received some pond plants back in the winter.
When they arrived, they had to be planted straight away, so I put them in the half finished pond.
The Aponogeton distachyos I put right at the front of the raised pond, so that I could smell it easily.
When it flowered, I leaned over to smell it, slipped on the rough unmade up path, and ended up with my whole head under water!!!!
It seems to have got over that, as it has grown and flowered beautifully since then. Now that it is July and hot however, it has gone into it's high summer minimalist mode.
I haven't yet got Thalia dealbata, but I grew it in Cornwall, where it was evergreen, even when the pond froze.
