scent and leafy. Leaves alternate, thickly

 acute or pointed. Stamens usually twice 

 as many as the petals, rarely equal in 

 number. Carpels as many as the petals. 

 Culture and Propagation. — All the 

 hardy House Leeks grow well in dry sandy 

 soil, and are suitable for the rockery, 

 on old walls or ruins, as edgings round 

 beds or borders &c. They are easily 

 multiplied by detaching the young plants 

 produced round the base, or from seeds 

 sown in finely sifted sandy soil, under 

 glass as soon as ripe, or in spring. As 

 soon as the young plants are large enough 

 they may be pricked out into well-drained 

 sandy soU, and it is safer to cultivate 

 them in pots in cold frames for the first 

 year before transferring them to their per- 

 manent positions in the open air.
