  It was irresponsible of Monty to advocate Euphorbia 'Fens Ruby' without pointing out how wickedly invasive it is - it gets everywhere, by root and by seed. Plant it only in dry shade ot you'll spend for ever weeding it out.
  And in my experience E. wulfennii varieties are not long live as Monty suggested. They become woody at the centre and die out after 3-4 years.

  My E. Fens Ruby is banished to the top of a dry wall and still it makes a bid for freedom! Still love it though.
  
  A very soothing programme tonight I thought, not much hard information bar pollinating daffodils, lots of pretty pictures of fritillaries, some enthusiastic but simple border renovation, just what my poor addled brain can cope with at the end of a hard week.
  
  Heaven forbid my horticultural brain cells should be stimulated by new information this late in the evening. Time for my cocoa I think..

  I dp agree with you about the Euphorbia "Fens Ruby ". I actually posted a warning on the Garden Clinic before I read your thread. I am plagued with this plant, pretty though it is, I wish I'd never bought it.

  Some can, yes. But others are just brilliant. E. palustris and E. polychroma stay put, clump up nicely, don't seed, are supremely hardy and have fabulous acid green bracts in spring. These would have been my choices.
  
  E. wulfenii died in all the gardens around here, including mine last winter, and E. Fens Ruby is a thug. Fireglow is good looking and well behaved enough. It does spread but controllable.

  Hi crouchee and trillium!
  
  Your advice please .... I have one almost impossible border, dry, dry, dry. It is backed by an 8-year old laurel hedge (conditions so difficult in this border, it has not yet had to be cut in height - now about 2m tall .... in places!). There are also 5 mature (at least 30 years old) maritime-type pines. Very sandy soil, good light in most of the border, facing full into the winds.
  
  I don't want to remove the hedge and the trees are so majestuous that I haven't the heart to destroy them.
  
  I grew euphorbia oblongata from seed about 3 years ago and it just loves the conditions there, and it seeds. The problem is E.oblongata is too short. I've tried E. welfenii but it didn't last more than a couple of years. So my question: is there a .... tall.......euphorbia thug? Inflorescence colour unimportant.
