EUPHORBIA CHARACIAS WULFENII
This outstanding and most attractive form produces imposing clumps of erect stems clad in narrow grey leaves terminating in large and almost spherical, football-sized heads of yellow-green flowers. These plants were originally seedlings from 'John Tomlinson' an exceptional form, with more rounded flowers. These imposing specimen plants will perform reliably where little else will thrive.
For best results, sow immediately onto a good soil-based compost. Cover the seeds with fine grit or compost to approximately their own depth. They can be sown at any time, and germination can sometimes be quicker if kept at 15 to 20 degrees C. We sow most seeds in an unheated greenhouse and wait for natural germination, as many seeds have built-in dormancy mechanisms, often waiting for natural spring germination, hence giving them a full season of growth.
