Watercress, akin to kale, broccoli, and Brussels sprouts, boasts a peppery flavour and thrives in gently flowing water, forming lush mats of nutritious foliage. Ideal for moist, sunlit spots, it can also be cultivated in water-filled containers to prolong its growing season. This fast-growing aquatic perennial forms dense mats of both floating and submerged stems that creates habitat for shallow water organisms. Its oval, wavy-edged leaves, rich in dark green hues, make Nasturtium officinale a popular choice for salads, complemented by delicate white flowers that bloom from late spring to midsummer.If using as a boggy/marginal aquatic, plant out in reliably moist or boggy soil, or pot up into a pond basket and place at the margins of a pond at a depth of 0-7cm (0-3"). Watercress prefers reliably wet soil so dot allow to dry out. Harvest/prune during the growing season once established. Choose our 9cm pot range for planting above the waterline, or our aquatic pot range for at below the water's surface. Position: full sun or partial shade Depth of water: 0-7cm (0-3in) Rate of growth: fast Flowering period: May to June Hardiness: fully hardy
