Lily of the Nile. An evergreen, clump-forming plant with white flowers ranging from 60 to 75 cm tall, blooming from late spring into early summer. The bright white flowers look great against a dark green backdrop of shrubs or when mixed with blue-flowering agapanthus — a typical combination in Mediterranean-style gardens. Like the other agapanthus, it is well suited to the Algarve climate due to its preference for full sun and tolerance of our clayey soil. It thrives in areas with a winter rainfall pattern similar to its native Western Cape in South Africa, where it grows in fynbos ecosystems on rocky slopes and sandy soils. While it can tolerate summer droughts in heavier soils, it benefits from regular watering during the growing season, particularly in spring and summer. Deep, infrequent drenching (once a fortnight) is more effective than frequent, shallow watering. Improving the soil by adding organic matter will also help it withstand droughts. For optimal growth, plant it in full sun and protect it from harsh winter frosts if you experience these in your garden. Fertilise with a liberal application of organic fertiliser in late autumn and spring.
