In the open ground this plant makes a densely leafed ground cover approximately 100mm in height. It prefers sunny positions where it has a mat-forming growth habit. It likes sandy, well drained soil, making it ideal for those spots in the garden where nothing else seems to want to grow, like dry patches in the full sun, or on sloping ground. It is ideal for rockeries or terrace walls, where it cascades down over the rocks.

Lifespan in the garden is approximately 4-6 years, but plants can be cut back and fed to improve their shape if required. It is better to use an organic food, such as compost or Seagro, rather than a fertilizer. This encourages slow growth. Fertilizers encourage the plant to grow too fast and exceed its growing capacity, making it lanky and woody. The striking contrast provided by the grey foliage of this plant makes it an ideal ground cover and border plant. It is also a good filler for pots, cascading down the sides. Like many ther helichrysums and grey leaved plants, H.argyrophyllum is drought tolerant, making it a good choice for the water-wise gardener. It also grows in semi-shade, but will not flower as prolifically as in full sun. The plant has a strong resistance to fungi and seems to be very unappetising to insects!

Propagation is by seed and cuttings. Seed is best sown in autumn or spring, otherwise the plant roots freely wherever the stem touches the ground. Heel or tip cuttings can be made, using Seradex #2 or Dip and Grow root hormone treatments.
