Shallow window box suggestions

thedjjjthedjjj Posts: 84

i have a shallow window box, full sun, about 100mm depth 1000mm long .. any suggestions on what might thrive here ? I guess it mimics a green roof type of planting and will be quite dry .. sheltered though. Completely open to colours and styles, as there’s currently nothing in it it’s wasted space !

    I chucked a shallow bed of sedums on top of our rabbit hutch. It's a bit of a long term plan but looks great when they're all established and in flower. Inch of gravel for the base and an inch of gritty soil with a gravel mulch on top.

    They tended to flower all at once though, albeit for a long period. I ended up mixing in some silver saxifrage in the centre and sempervivums at the edges which helped spread the season out. I got some great flowering spikes from the saxifrage.

    Sadly I've had to take it all apart now as they developed the plot behind it and that part of the garden fell into the hole they dug. Another benefit of sedums though is that they transplant well.
    A great library has something in it to offend everybody.

    Alpines might be a good bet. It sounds like you have the right conditions. A try of very gritty, low nutrient, alkaline soil. Sunny, pretty dry, like a min-rock garden. Also things that trail over your window sill would give you added volume. Some GW alpine suggestions here.
