Irish moss (Sagina subulata) is a slow-growing perennial resembling moss. Ideal for rock gardens & paths, it thrives in sunny to partially shady spots.
Keep soil consistently moist, not soggy. Use a soaker hose on mild rainfall setting. Water every few days, especially in heat, preferably in the morning.
Irish moss thrives in USDA Zones 4-8. Outside these zones, it struggles in hot, dry summers. Consider container gardening, movable for shade in hotter climates.
