In short: I need help, advice, suggestions, etc. Bring it! I have no idea what to do.
See the attached picture? That's the sceptic mount/drainage field behind our house. That lump. Yeah. Ugh. I'm not best pleased about it, but it's what's needed to ensure flushing toilets that don't flood into the foundation or the pipes, so fine, I'm dealing. But the visual is not the prettiest, and the angle of it is enough that I'm not super-keen on planting it in grass, because I think it'll accentuate the "this is a grassy lump" visual and also because I really don't feel like lugging a push mower over this every week (ahem. every two weeks.)
The vegetable garden is on the other side of the house in garden boxes. The front of the house is being planted with bulbs and lilac bushes and the like. We can't plant edibles there, apparently - some concerns about leak-through grossness from the sceptic tank.
So... HALP. I want something pretty and low-maintenance that has a chance of surviving Quebec winters and that doesn't mess up the drainage (aka: no trees, things with huge roots, bulbs, etc).
We were thinking of potentially putting the sheep field on the other side of the mound, possible with the gate running over the top of it, but that still leaves the side facing the house (what's in the picture) looking kinda blech. I was considering green options (creeping thyme? maybe? but that's a LOT of space, and would probably be pricy...) or maybe just wildflowers (suggestions?), but seriously, if anyone has any ideas, I'm all ears.
