The tender tuberous roots of this plant with fragrant blue lily-like bells above ribbon-like foliage (it attains a height of 3 feet) should be planted in March in rich soil consisting of equal parts of garden loam, peatmoss or leafmold, and well-rotted manure. Agapanthus likes plenty of moisture while growing during spring and while blooming through the summer, but taper off with the water during fall.
While plants are dormant during winter, water sufficient only to prevent foliage from drying up should be given. Flowers of lovely shades of blue are produced all summer on long stems above fairly short, strap like foliage. Twenty or more individual blossoms centrally joined to the tip of the long stem form a cluster of thin tube-like throats ending in six petals of lily-like florets. Agapanthus do best in tubs or large pots, as roots are strong and large; if sufficient root space is provided they will not have to be repotted for several years.
Occasional applications of manure "tea" are helpful. Repotting, when necessary, should be done in late winter or very early spring before new growth starts. New plants may be started from root divisions at time of repotting.
