Sedum kamtschaticum

Russian Stonecrop is smothered in stunning yellow star-shaped flowers with orange eyes at the ends of the stems from early to mid summer. Its succulent oval leaves remain dark green in colour throughout the season. A ground hugging mop of deliocius colour in sunny and dry spots. A fantastic garden edger.
