Senecio Stapeliiformis, also known as Kleinia stapeliiformis, is an attractive succulent plant perennial which has distinctive pencil-shaped stems with soft spines and purple-green patterns. For optimal growth, the pickle plant should be placed under full sun to partial shade. Once the pickle plant has become well established, it is highly drought-tolerant. It still needs water, especially in the summer season. However, you need to make sure its soil doesn’t stay wet for an extended period.
