FAQs

Does Snow in Summer grow back every year?

Yes, it is a hardy perennial. It will die back in autumn but will regrow with fresh, vibrant foliage every spring.

Can I grow this in a pot?

While it is primarily a ground cover, it can be grown in containers, provided the pot has excellent drainage and is not allowed to sit in water.

How far apart should I plant the pots?

Plant them approximately 20-30cm apart to allow them to spread and merge into a single mat over time.

Is this plant deer-resistant?

Generally, it is not a favorite for deer, though no plant is 100% immune if deer populations are desperate for food.

Do I need to fertilize it?

No, it prefers poor, dry soil. Over-fertilizing can lead to weak, leggy growth rather than a compact, flowering mat.

Troubleshooting

Plant growth is sparse or leggy

This often occurs due to lack of sunlight or excess water. Ensure the plant is in a sunny spot and avoid overwatering.

Flowers are not appearing

The plant may need a trim after the previous season to encourage fresh growth, or it may be competing with aggressive neighboring plants.

Center of the clump is dying out

This is common in older plants; lift and divide the plant in spring, discarding the woody center and replanting the healthy outer sections.

Pros and Cons

Pros

  • Excellent for suppressing weeds in gaps and borders
  • Extremely drought tolerant once established
  • Visually striking silver-grey foliage provides color year-round
  • Hardy perennial that reliably returns each spring
  • Ideal for rockeries and wall crevices

Cons

  • Dies back completely in autumn, leaving empty space in winter
  • Can become invasive if not pruned after flowering
  • May require division every few years to keep clumps vigorous

Setup, Compatibility & Care

When planting, choose a spot with well-draining soil, as this plant dislikes sitting in heavy, waterlogged ground. Dig a hole twice the size of the 9cm pot, place the plant at the same depth it was in the container, and backfill with soil. Water thoroughly until established. For maintenance, prune the plant back firmly after the flowering season to encourage a compact, dense shape. If the plant center becomes woody or thin after a few years, divide the clumps in early spring to rejuvenate the growth.
