AGAPANTHUS. (AFRICAN LILY.) 



Description. A beautiful genus (ord. Liliacese) 

 from the Cape of Good Hope, suitable for growing 

 in pots for greenhouse or conservatory. They are 

 hardy in some mild, sheltered districts. 



Propagation. From seeds occasionally, but 

 chiefly by division of the roots in the spring. Wash 

 the soil from the roots, divide the bulbs singly or 

 in masses of several, giving pots to suit the size of 

 divided pieces. 



Soil. Agapanthuses being often grown in large 

 pots or tubs, in which they are allowed to remain 

 undisturbed for several years, it is worth while t<> 

 prepare a good compost. Three parts of sound 

 loam, with one part of decayed manure and a liberal 

 sprinkling of sand, will suit. 



Cultural Points. No greenhouse plant is easier 

 to manage. The roots will bear confining, and 

 large specimens will go for several years without 

 re-potting. A cool house from which frost is ex- 

 cluded is suitable for wintering the plants. Give 

 little water during the resting period. Plant out- 

 doors in sheltered situations in beds and borders, 

 and on the banks of lakes. It is advisable to afford 

 some protection to the roots in the winter.
