These pods, containing seeds with 'silk' or 'cotton', are highly ornamental and often used in dried floral arrangements, while the plant itself adds unique architectural interest to low-maintenance gardens or as a focal point.

Care tips
It thrives in full sun exposure for optimal flowering and fruiting. Watering should be moderate, allowing the soil to dry out between waterings, as it is drought-tolerant once established. Use a well-draining, sandy or rocky substrate; overwatering is the most common mistake to avoid, as it can lead to root rot. Prune lightly after flowering to maintain a compact shape and encourage more pods.
