Agapanthus 'Happy Blue' Overview
Agapanthus 'Happy Blue' is a deciduous clump-forming perennial that produces charming light violet-blue flowers in late summer, whose petals have a deeper blue central mark. Forming rounded flower heads, they stand tall on erect stems, above glossy dark-green strap-like leaves. The tubular flowers fade as they age and hang downwards. The flowerheads are followed by attractive seedheads in the autumn. Also known as African Lily 'Happy Blue', these stunning South African plants look particularly good in Mediterranean style gardens or patio containers. But they need to be brought under cover during cold winters. In warmer areas, Agapanthus can also be planted into sheltered borders provided the soil is not too fertile, and where applying a winter mulch of leaf mould will help provide winter protection. Like all African Lilies, Agapanthus 'Happy Blue' prefers a sheltered position in full sun and free-draining soil. For best results, apply a balanced liquid fertilizer monthly from spring until flowering. Cold, wet winters are the main enemy of Agapanthus. If you are growing in containers, contrary to popular wisdom, Agapanthus do not like to be overcrowded. However, they also take a while to establish if planted up into too large a space. As a rule of thumb, pot on every two years using a gritty multipurpose mix. This lovely cultivar has earned a coveted 'RHS Award of Garden Merit'.
