Tasteless Stonecrop


Sedum sexangulare (Tasteless Stonecrop)

Sedum sexangulare (Tasteless Stonecrop) is a mat-forming succulent with ascending, branched stems that bear fleshy, bright green leaves…

Use in the garden

Tasteless stonecrop fits wonderfully in steppe beds, stone and gravel gardens, in wall cracks and stone joints and is the perfect solution for problematic dry locations. The sedum is also used for extensive roof greening or as a lawn replacement. For combining in the garden, for example, Serbian bellflower (Campanula poscharskyana), Mediterranean sea holly (Eryngium bourgatii), Turkestan onion (Allium karataviense), St Bernard’s lily (Anthericum liliago), dwarf feathergrass (Stipa capillata) as well as spring-flowering bulbous flowers are suitable.

Tasteless Stonecrop

Sedum sexangulare

  • Name also: Watch-chain Sedum, Six-sided Stonecrop, Insipid Stonecrop
  • Family: Stonecrop Family – Crassulaceae
  • Growing form: Perennial herb. Loosely tufted.
  • Height: 3–8 cm (1.2–3.2 in.). Stem ascending–limp.
  • Flower: Corolla regular (actinomorphic), bright yellow, approx. 1–1.5 cm (0.4–0.6 in.) wide petals five, 4–5 mm (0.16–0.2 in.) long. Sepals 5. Stamens 10. Gynoecium with separate leaves, pistils 5. Inflorescence a 1–3-flowered cyme.
  • Leaves: Alternate, in clear rows especially on flowerless stems, stalkless. Leaves on flowerless stems very dense, sparse on flowering stems. Blade obovate–linear, blunt-tipped, cylindrical, fleshy, glabrous, dark green–reddish.
  • Fruit: Cluster of 5 many-seeded, basally united follicles.
  • Habitat: Rocks, hill slopes, meadows. Also an ornamental, occasionally wild.
  • Flowering time: June.

The Finnish soil has been affected by the Ice Age and its after-effects. There has not been enough time yet for all the rocks to be covered by earth, and there are still plenty bare and thinly-covered rocky outcrops, which have become home to plants that are particularly fond of dry, hot places. Compared to other plants that grow in Finland, succulent-leaved stonecrops are the best able to withstand long periods of drought. Tasteless sedum only grows on the main island of the Åland Islands. The species’ spread is limited by both climate and soil: the Åland Islands has a temperate maritime climate and rich, calciferous soil. Tasteless sedum is occasionally cultivated in gardens as an ornamental, like many of its relatives. It makes a great ground-cover plant as it forms dense, low, lively green moss-like stands.

Tasteless stonecrop looks very much like biting stonecrop (S. acre), but its stem has edges and its narrow leaves are arranged in five or six rows. This is particularly obvious on flowerless stems. One way of telling what plant you are holding is to taste it: Tasteless stonecrop has a mild flavour (of course) but biting stonecrop is extremely bitter. This bitter juice is in fact poisonous and can even cause a rash on the skin. In habitats that are common to both species watch-chain sedum begins flowering a couple of weeks later than its relative. Biting stonecrop is the more common of the two and grows ferally, also on mainland Finland as far north as northern Ostrobothnia.

Gardeners' Notes:

On Jun 30, 2012, Clary from Lewisburg, PA (Zone 6b) wrote:

I have downgraded this plant to a negative. It spreads so invasively that I had to remove the entire patch and a 1' periphery just to be sure. When handled the plant breaks apart and the smallest bit will root and spread. Accidentally hit it with the snow shovel and it's 1000 new plants wherever the pieces land. Although the flowers are brilliant, the plant looks brown all over once they die off. Couldn't weed whack or shear the dead flower heads for fear of spreading little bits of sedum around. It's gone now, and thank heaven none of it got into the lawn.

For eastern United States zone 4, this little guy is one of the top 5 toughest of the true sedum family - they shrug off the rains, winter snow cover, etc.

Lovely little filler plant - great for front of a border. I've found babies of it up to a foot away that are easily moved. Good manners, non-invasive. Ours is in half sun all day.
