Agapanthus Sweet Surprise is certainly surprising as a variety! While Agapanthus are typically a deep blue or purple colour, this variety bears bright blue flowers with distinctive dark blue stripes down the inside of each petal. These flowers are held on large flower heads, home to numerous trumpet shaped blooms that are present from late Summer to early Autumn, held atop stems that can grow up to a meter tall. Below, this variety's foliage forms in a mound with long, thin, strap shaped leaves that are perfect for use in a pot, where this foliage can spill over the edges and give a natural effect. This perennial is drought tolerant, pest and disease resistant, and doesn't require pruning after its flowering season has ended, making it very low maintenance for how impressive its displays are! It's also a great variety for gardens looking to introduce or cultivate existing wildlife, particularly pollinating insects. Bees and others adore their flowers, and this variety holds the RHS Plants for Pollinators award, which means that they are certified as being suitable for bees and other pollinators.

Planting Conditions

Agapanthus like moist but well drained soil, made from clay, sand, chalk or loam, at any pH. They should be planted in a sunny spot with at least 6 hours of sunlight a day, and that spot should be sheltered to ensure their best performance. When potted, Agapanthus are more floriferous, however they can work well planted in a bed or border too as long as the soil is freely draining.

Watering & Feeding

Agapanthus don't need as much water as other perennials, so the soil around them will need to be freely draining to ensure they don't stay too wet. They should be watered once or twice a week, though if you're looking for a good way to tell exactly when, just check the top inch of soil and water them if it's dry. The best time to fertilise them is in Spring and Summer with a 1-2-1 or balanced ratio fertiliser, as this will ensure they perform well.

General Care

Agapanthus require little maintenance as they need very little water and don't require extensive means to avoid disease and pests. They will need protecting in the Winter where the frost can kill them if they aren't in a greenhouse. When planting, a hole twice the size of the pot should be dug and the plant placed into it, filling in the remaining area in with compost. A 3 inch layer of mulch should then be applied around the base of the plant, and it should then be watered to keep the soil moist while it establishes in its new spot.
