Euohorbia 'Diamond Frost'
I'm reposted this with a picture
Has anyone grown EUPHORBIA 'Diamond Frost' ? I found some ay a local "Shed" today, reduced so I bought one to try, Great looking plant a mass of very small flowers http://i240.photobucket.com/albums/f...0flowers/Eupho... I am finding a lot of mixed info on line, such as Burncoose saying "Frost hardy - Plant can withstand temperatures down to -5°C (23°F) " then saying " Not the sort of plants to be grown outside where there are likely to be frosts. These plants need to be grown in a conservatory or cool greenhouse or at least brought inside for the winter - where it should continue to bloom. " U S of A sites describe it as a tender annual. I'm confused David Hill |

Euohorbia 'Diamond Frost'
To a degree 'Diamond Frost' is a bit of a 'one hit wonder' because
although it is technically a short lived perennial. it is best grown on from cuttings each year and most plants are treated with Cycocel to encourage a bushy and more compact habit. Left to its own devices, it is a more open, slightly taller plant. It is a cultivar of Chamaesyce (Euphorbia) hypericifolia, which is a warmth loving 'spurge' native to the warmer regions of the USA and central America. The species proper is a low growing plant that revels in heat and light, often turning purplish with exposure. It is becoming naturalised in many parts of the world and seems to be acquiring almost a 'weed' status, which shouldn't concern us unduly in our cold, damp climate. It can be overwintered outside here, but only in very sheltered, well drained spots and it certainly wouldn't survive many -5C nights. Mine survived two winters only to be killed by an unusually sharp, late frost in spring. Good drainage is essential and 'Diamond Frost' is better overwintered at around 5C and kept only lightly moist and in good light. You can then take cuttings in early spring, but the resultant plants will be somewhat more airy and open unless treated with the growth regulator. Nevertheless, it is a very pleasant thing with or without the retardant and makes a splendid foil for more vividly coloured plants. It is glorious with dusky leaved Dahlias, but to my mind looks a bit contrived when associated with rich purple leaved forms such as the Llandaff 'tribe'. |
