✂️ Care

Plant in full sun to partial shade in rich, well-drained, neutral to slightly acidic soil. Water regularly at planting to encourage root development, then maintain consistent moisture throughout the growing season.

Prune in spring before new growth to maintain a rounded shape and encourage generous flowering. Apply organic mulch to retain moisture and regulate soil temperature.

Perfect for medium-sized gardens, structured beds, and landscape designs, this variety offers prolonged flowering and remarkable visual interest with its brilliant white, generous globe-shaped flowers and regular maintenance once established.
