Only make sure, that you have enough time to take care of it. Dirty water full of glones will not make a pleasure...
Take a tour...
Hippuris vulgaris looks always good in water - like tiny christmas trees!
It came to me from the river near by. I don't know name of it.
Typha minima - perfect for small ponds, not growing too fast.
After 2 years frogs came to me. This one is probably Rana lessonae. It didn't get scared of my 2 cats Aslan and Atomic, or other cats which visist my garden everyday.
Sympetrum vulgatum. "Vulgatum" sounds very ordinary - and in fact it is dragonfly rather boring in colour. There is few kinds of them appearing around, but.. let's be honest... try to make a good photo of fast flying and restless dragonfly... with frogs it is easier :)
If you are raised at the lake you will always miss it. Maybe this pond is not ehe ehe... lake, but it relaxes like noting else. Sound of water running, becomes music of your garden day.
