Enviromat sedum matting has a lovely long flowering period.  The different sedum species tend to bloom one after another which means that ground cover and green roofs can be interesting from spring through to autumn.  Let’s take a look.

Oh – one thing to mention.  Once Enviromat has been in place for a while, the mix and proportions of sedum species will change. The way that the plants thrive and compete with each other for light and space depends very much on local conditions.  Aspect, weather, drainage, temperature, nutrient levels moisture levels and a whole host of other factors will determine which species thrive, survive or perish.  You will probably see differences from year to year – that’s the mystery and the beauty of nature.

Spring

The first flowers to show themselves in spring are usually Meadow saxifrage and Sedum Album.  Flowers start appearing in late April and bloom through May, sometimes into June.

Late Spring

From late spring onwards Sedum Pulchellum throws out it’s firework like flower heads.   Sedum Kamtchaticum brings a comforting yellow glow to the matting.

Sedum pulchellum has pink florets arranged on a star shaped flower head.

Early Summer

Watch out for the first signs of Sedum Spurium.  The main flush of these flowers comes in July and August but sometimes a few appear earlier.  The large flower heads are distinctive and come in several different shades of pink.

Also blooming in early summer is Sedum reflexum with its fresh yellow flowers.

Sedum Hispanicum blooms in June.   The pale pink flowers are not all that spectacular to the human eye but pollinating insects absolutely adore them.  Hispanicum is a relatively new addition to the Enviromat seed mix, established Enviromat may not contain this species.

Mid-Late summer

Expect to see a lot more of Sedum spurium and a second flush of Sedum Kamtchaticum too.

Autumn

If the weather stays mild, don’t be surprised if your Sedum spurium continues to flower furiously right up until the first frosts.   This plant offers really good value for people and pollinators alike.

Sedum Spurium offers sustenance to pollinating insects long after many of our wild flowers have finished blooming and started to set seed.

Winter

It’s not usual to see Sedums blooming through the winter months.  What you will see instead of flowers is beautiful foliage.  The fleshy leaves of many sedum species change their appearance in winter and become a lovely russet colour.
