Spring and summer are when sedum green roofs are at their most beautiful and their most productive (in terms of providing pollen and nectar for insects)
Here are some images of sedum plants that thrive on green roofs and offer great value for local pollinators.
Sedum Pulchellum. An eternal favourite of mine. This little plant seems to flower twice a year. Once in late spring and again in early autumn. What I love most is the way that individual flowers are arranged on a star-shaped bloom. Hence its common name of “widows cross”. To me though, it looks like a firework. Love it!
Sedum album. Amongst one of the first flowers of the year on a green roof. Sedum album is the perfect green roof plant. It’s hardy, drought tolerant and probably one of the most shade tolerant green roof plants. (although it won’t take deep shade). When you see a whole host of these pinky-white flowers together they look like fluffy candy-floss.
This is why sedum album is such good value on a green roof. This is how the plant looks in winter. It keeps its foliage and therefore its ability to trap air and insulate a building. It also takes on this beautiful colour. What more could anyone want?
Sedum kamtchaticum and Sedum album growing together. I love this plant combination. Such fresh colours.
This photo was taken in May.
Seems I’m not the only one who likes Sedum kamtchaticum. This honey bee is after the nectar that is so plentiful in all sedum plants. Kamtchaticum is a nice low growing sedum, winter hardy and generally undemanding. It’s great for green roofing. Not everyone loves the colour yellow but somehow it doesn’t seem so offensive when it’s up on roof.
Sedum spurium. Every green roof should have some of this. These flowers come in all shades of pink, from baby pink to hot pink and everything in between. These plants love sunshine and they will attract every pollinator for miles around. Normally they start flowering in July and keep going until the first frosts. Providing valuable bee forage when there are few other sources of nectar.
Finally, this is what it’s all about. Green roofing using sedums. They don’t need much growing medium so a sedum roof puts far less strain on a building than say wild flowers. Sedum green roofs are floral, they’re beautiful all year round, they’re functional (particularly if you happen to be a bee) and I love them.
