232 ROCK GARDENING FOR AMATEURS 



is very similar to the last, differing chiefly in the leaves, 

 having a more distinct and wavy margin. L. rediviva 

 is quite distinct from the last ; it forms a rosette of small 

 terete leaves, which die down before the flowers appear. 

 Each plant has usually two or three expanded blossoms 

 at a time, each from two inches to three inches across, 

 and soft rose in colour. It is a native of California, and 

 requires similar treatment to Calochortus. L. Tweedyi

 not so hardy as some of the others, and is best grown 

 in a pot in a frame, where it gets shelter, although it has 

 been grown outside in sheltered places. All flower in

All these plants must be grown in a sunny place,

 moisture is fatal to them. 



Lilium (Lily). Liliums are not usually included 

 amongst rock-garden plants, but in many parts of the 

 rock garden there are often half-shady spots for such 

 things as Erythroniums and the shade-loving Primulas. 

 Here some of the Lilies may go. They belong to the 

 natural order Liliaceae. Some of the Lilies prefer a peaty 

 soil, and this applies more particularly to the North 

 American kinds, of which there are some that do not 

 grow too big. In a bog or moist peaty bed the Cali-

 feet high, and bearing in June several trumpet-shaped, 

 lemon-yellow flowers, that are sweetly fragrant, may be
