Binstore Green Roof (Part 3): Plants, plants, plants…

We’ve had our binstore with its green roof since March and it’s been lovely not to return home each day to our recycling bins lining the drive. In that respect the binstore has been a great success, but until this week the green roof was only very partially planted, waiting for me to source more plants and get round to putting them in. The substrate had been added and the binstore even has resident bees nesting in the holes in the side, so now it’s time for the best bit – choosing and adding the plants.


The thyme corner

The first plant to go in was Thymus vulgaris ‘Silver Queen’. Thyme seemed a natural choice as the site is in full sun and the substrate purposely low in nutrients to make it suitable for sedums and other alpine plants. Next I added two small sedums which I found at my local nursery – Sedum spathulifolium‘Cape Blanco’ and Sedum spathulifolium ‘Purpureum’.


The first few plants arrive…

To Eat or Not to Eat?

I had a few Dianthus deltoides and Armeria maritima left from some planting in the front garden and gravel path, so I also added these to the roof. By this point I’d abandoned the principle of only including edible or otherwise useful plants and decided that aesthetic appeal could also count on the ‘useful’ front as they make me feel good, especially when the Sedum ‘Cape Blanco’ flowered and then retained its yellow flowers for weeks and weeks. I’ve also decided not to grow alpine strawberries on the roof this year. I was intending to dig up some Fragraria vesca ‘White Soul’ which I’d grown from seed last year and planted temporarily in the front garden, but their temporary position seems to be suiting them and they’re thriving, so it seems a shame to move them. Instead I’m going to grow some more from seed and plant them in the roof next year.

Handy Herbs

Then, earlier this week, I was ready to add the rest of the plants. I planted an Indian Mint (Satureja douglasii) which is a lovely trailing herb with light green leaves and dainty white flowers. It can be used as edible edging in hanging baskets and containers, and although it isn’t a true mint (it’s a tender perennial), it can be used to make an aromatic mint tea. I also planted another Satureja – Satureja montana or Winter Savoury. This hardy perennial is great with mushroom dishes and in stuffing. It can also be used as a replacement for thyme in many recipes. Salad Burnet (Sanguisorba minor) joined the herb collection, to be used as a cucumber flavoured addition to salads, sauces and sandwiches, along with French Tarragon (Artemisia dracunculus) for adding flavour to chicken dishes.

Edible Flowers

I’d grown two varieties of nasturtium from seed – Tropaeolum ‘Tip Top Velvet’ and Tropaeolum ‘Salmon Baby’, so I added my small plants around the back and sides of the roof. These will hopefully trail downwards to create colour and also provide spicy leaves and petals for salads. Previously I’ve grown nasturtium in the veg beds with the kids and they haven’t flowered well, possibly because the soil is too high in nutrients. I’ll be interested to see if they flower more prolifically in the lower nutrient content of the green roof substrate.

Local Treasures

Last weekend I spent 12 hours over two days selling plants I’d grown from seed at my son’s school fete and at our local community garden open day. I love meeting people who are interested in plants and helping to raise money for good causes. I also get to explore other people’s plant donations and add to my own stocks by buying a few lovely specimens. This year I bought some Sempervivum arachnoideum to add to the green roof and some cheerful dahlias for the pots at the front of the house.

Thyme and Chillies

I added another thyme – Thymus x citrodora ‘Aureo’ next to the silver thyme and then I selected several chillies from my seemingly endless collection this year – ‘Piri Piri’, ‘Habanero Red’, ‘Habanero Big Sun’, Prairie Fire’ ‘Albertos Locoto’ (tree chilli) and ‘Jalapeno’ and planted them in the middle of the roof. I’m not sure whether they’ll thrive – it’s a bit of an experiment. I’m going to feed them to encourage flowering and fruiting and we’ll see how it goes.

Climbing Companions

Finally I planted some Thunbergia (Black-eyed Susan) at the base of the binstore where they will hopefully climb up the trellis, covering the front with summer colour and meeting the nasturtiums as they trail downwards.

And within a week has produced its first flower

An Inspiration Gap

There is still one space at the back of the roof which is empty. I’m not sure what to add to finish the roof for this season – it needs to be happy in full sun, be able to tolerate fairly poor soil, look attractive and, if possible, be edible. I’d love to hear any suggestions for this space as it’s always great to grow and learn about new plants.


The final space…

Over to You…

Please leave me your plant suggestions in the comments and I’ll pick one or two to plant in the roof. I’ll include a comment below in a week or so, to explain which suggestions I’m going to get and why. Then I’ll post again later in the summer when I’ll hopefully be able to share images of the plants in at their best, including the selections offered by my readers.

Thank you in advance and do subscribe to my blog so that you’ll hear about the progress of the green roof in a few weeks’ time.

    I see now what you said about the Alpine Strawberries! Your binstore roof seems to have a bit of something of everything on it already! Always room for more herbs though. Are there any Chives? Oregano? Golden Marjoram?

      I think chives would be a good idea instead of thrift if someone wanted an edible alternative. I like the idea of golden marjoram. I’ve used it in designs before and it has a lovely way of adding a lift to a herbal scheme 🙂

    Thanks to everyone who left me a comment on the blog and on other social media sites. I’ve learnt about new plants and had a good think about what to add to the last space. I think next year I’ll try micro veg and wild rocket nearer to the edge of the green roof. The space left this year is rather less accessible, so a cut and come again crop might be a little tricky to sow and harvest. Instead this year I’m going to plant a golden marjoram as I think it will add visual interest to the roof garden. Next year I might also try growing Hottentot fig (Carpobrotus edulis) from seed (Chiltern Seeds sell it) as I love the idea of an edible succulent. I think we’re too far from the sea for any risk that it might escape and become invasive and it would only be grown as an annual. But I’ve always loved mesembryanthemums, so the idea of a similar plant but with edible qualities, is exciting. Thanks again for your suggestions – isn’t the learning which comes with gardening, great fun?
