Plants for a waterlogged garden?
We've been living in our rented house for about a year now, and I'm having real trouble with knowing what plants to chose for our 'garden'. I say 'garden' in inverted commas because there's no soil in it, it's entirely concreted over.
It's very shielded, with the house on one side and high fences around it, so although parts of the area get full sun for part of the day, none of it has full sun.
And because the ground doesn't soak up moisture, it's ALWAYS damp. I have a very nice Houttuynia cordata Flame that seems to love the conditions, and a few strawberries in a large planter that seem happy enough, but everything else seems to give up the ghost within weeks.
Can you please recommend some more plants, prefereably perennials, that will enjoy being in the space? It would nice to get lots of variation on height, leaf shape and colour to give us something to interesting to look at throughout the year.
Easy maintainance would also be a plus as I've never had an outdoor space before and really don't know what I'm doing!
