Answer: Lily-of-the-Nile is Agapanthus, an adaptable perennial that grows in full sun, or in as little as 3 hours of sun a day. It thrives in loamy soil but will grow in heavy soils, and gets along with very little water, even in the summer time. I suspect that you're overwatering your plants. Try watering only once every 2-3 weeks, watering deeply and thoroughly so the entire rootmass gets wet. You can feed your plants a diluted liquid fertilizer about every 4 weeks during spring and summer to help them green up a bit, or you can mulch the top of the bed with compost to provide nutrients over the entire growing season.
