Sedum Mexicanum ‘Lemon Coral’, aka Lemon Coral Sedum, Sedum Lemon Ball, or Sedum rupestre ‘Lemonball’ (along with many more names), is a gorgeous succulent with eye-catching foliage of yellow, bright green and chartreuse colours. The pointed, tiny, slightly plump leaves are actually quite soft and will begin to trail making it ideal to grow in a hanging planter.
