Plants next to " rain water channel"
have a backyard through which runs a "rain water channel". Sorry if this term is not correct one, but what I mean is that this channel is meant for rain water to flow through my backyard. Backyard does not receive a lot of sunshine i.e. there is quite a many trees.
I would like to plant there right next to this channel some flowers and/or bushes. And I would appreciate any insights into which flowers and/or bushes would be suitable here i.e. ones that do not require a lot of sun and would be fine even if there would occasionally flow rain water. But perhaps this "rain water channel" is not a problem at all here?
