Soil Type

Water: Silver mound 'Nana' thrives in temperate regions with moderate moisture and well-drained soil. It needs weekly watering to maintain its silvery foliage, balancing drought resistance and hydration. Often used in rock gardens or as border foliage, mulching helps retain soil moisture and reduce watering frequency.

Fertilize: Silver mound 'Nana' thrives in poor soils and requires minimal fertilization. Over-fertilization can cause leggy growth. Apply a small amount of compost or organic fertilizer in spring or fall to supply essential nutrients.

Pruning: A low-growing perennial, silver mound 'Nana' features silvery foliage and benefits from annual pruning in early to late spring. This process encourages dense growth, maintains shape, prevents legginess, and enhances its ornamental appeal, supporting vibrant recovery throughout the growing season.

Propagation: Silver mound 'Nana' thrives when propagated through cuttings from healthy, non-flowering shoots. Use a well-aerated, moisture-retentive medium, and protect from temperature extremes for optimal rooting. Once established, transplant into potting soil where silver mound 'Nana' adapts well to new conditions.
