Sedums are amazing. Such fascinating foliage and so easy to care for. We’re taking a closer look sedum plants, where to buy them and how to grow them.

What are sedum plants?

Sedums are what we call succulent plants. They have thick, fleshy leaves with a tough skin that helps them to cope well with drought. Sedums are from the genus crassulacae and are related to aloe vera and pineapple plants.

Flowers are usually white, yellow or various shades of pink. Each individual floret has five petals, arranged in a star shape. They open wide to allow bees and butterflies easy access to the rich nectar. Foliage colour varies from a grey-green to a really deep green and the leaves can be bean-shaped, flattish or roundish. In short, it’s a pretty diverse species.

There are around 400 different sedum species and countless varieties within each species. Not all of them can live outside all year round in the UK. So for this blog, we’ll look at the sedum plants that do well in this country.

Where to grow sedum plants

Sedums like well-drained soil – but it doesn’t need to be deep because they’re very shallow rooted. They also like – no – need – sunshine. Sedum plants just will not thrive in deep shade. Unless they have sun for at least half a day, they’re just not as happy as they could be. Neither do they like to have their feet wet for long periods of time. They’ve evolved to live in poor soil with few nutrients and not so good water retention.

In the wild you’ll typically find sedums on mountain sides, on the Norfolk Breckland (where the soil is very sandy) and growing in cracks between rocks. The Romans used to call them “wall pepper” because they have a bitter taste and grow on walls and seemingly soil-less surfaces.

Where sedums grow well

  • In an alpine trough
  • A rock garden
  • As groundcover plants
  • In pots and planters
  • Sunny windowbox
  • On top of a bird feeder
  • On a living green roof
  • Amongst other herbaceous bedding
  • In a “dry garden”
  • On top of a wall
  • In the cracks of a drystone wall

Growing sedum plants in the UK

First of all, do some research and discover which species of sedum plants are frost hardy in the UK (unless of course you are able to protect the plants should we have a harsh winter.)

My favourites are

  • Sedum Acre – which is native to the UK
  • S. Album – another native
  • Sedum Reflexum. Not native but it’s been in this country since Medieval times when it was imported as a salad plant. I love the look of the plant but believe me, it doesn’t taste nice and I won’t be adding it to my BLT at lunchtime.
  • Sedum Spurium. Broad leaves and large pink flowers
  • Sedum Telephium – also known as orpine. A taller species that has lots of different varieties. I have the one with pale pink flowers and grey green leaves in my garden. My honeybees treat it as a fast-food restaurant. They absolutely adore it.  There’s also a purple-leaved variety that I’d like to get my paws on.
  • Sedum Kamchaticum. Bit of a mouthful to pronounce but a lovely plant with happy yellow flowers.

I should have mentioned before that all of these sedums are remarkably disease-free and very easy going.

Make sure that you have prepared a sunny spot for them in the garden where the soil is free-draining (dig in plenty of gravel). Then all you have to do is plant the plants, water them in and watch them grow. I like to give them a high phosphorus feed in spring time to encourage flowering and apart from that they need very little attention.

Sedums are an ideal plant for people who can’t spend a lot of time gardening but still appreciate the beauty of living plants. They’re also great for growing less accessible places like roofs.

I’m a big fan of green roofing. I love the way they look and I especially like their potential to improve air quality, reduce heating bills and support wildlife.

Where to buy sedum plants

Individual plants are available from most garden centres and they’re nearly always reasonably priced.

If you prefer to buy online, there’s a nice selection at www.simplysucculents.co.uk

But for covering an area quickly and effectively, I thoroughly recommend using sedum blankets. All the planting has been done for you. Your main job is to unroll the blanket onto a suitable surface and water it in. Hey-Presto! Instant coverage for your shed roof, your flower beds, your manhole covers, pond edging or wherever you choose to use it.
