 is an exceedingly showy Primrose when grown under 

 proper conditions. There are many named varieties 

 of this plant, the best being Lilaeina, Magenta Queen, 

 Rosea alba. Rosea striata and Violacea. A light soil 

 well enriched with decayed leaf -mold, a sheltered 

 position with partial shade and a covering of dried 

 leaves in the winter are the requirements necessary 

 for success with this Primrose and its varieties. This 

 plant makes an excellent pot-plant and is easy to force 

 in spring. • 



There are a number of species of Primula that are 

 grown in the greenhouse, but the most popular is P. 

 Sinensis. By selection and crossing there are many 

 improved varieties from the pale pink plant that was 

 introduced in 1820. Every shade of color from pure 

 white to deep crimson and even deep blue is obtained in 

 the flowers and also great variety in form and double- 

 ness. Not only has the flower been improved, but there 

 is a great variety to be had in foliage. The double 

 forms are increased by cuttings; semi-doubles are raised 

 from seed. The named varieties are raised from seed 

 sown annually and they come true to color. There are 

 several strains of si-fil which receive separate names,

be potted off singly into 3-incb 

 pots, using a compost slightly rougher than the one 

 used in the seed-pans. When the small pots are filled 

 with roots the plants may be shifted into larger ones, 

 the final shift being into 6-inch pots, using a com-

thing to do then is to prick off all the young plants into 

 fresh soil similar to the above. Shake a little fresh soil 

 over the seed-pan again and place it in the same tem- 

 perature, and very soon the remainder of the seed will 

 germinate. When the young plants have three or four 



post of good fibrous loam, rotten cow manure, leaf-mold 

 and sand. When given the final potting care should be 

 taken that the base of the plant rests on the soil, but it 

 should not be buried. If the plant is not potted right 

 it will be loose at the crown. When this is the case the 

 only remedy is to place three small stakes in a triangle 

 round the crown; this helps to keep the plant steady 

 when top-heavy with blossoms and foliage. When the 

 pots are full of roots, weak liquid manure made from 

 fresh cow manure may be given once a week. During 

 the summer they require shade and should be grown in a 

 cool greenhouse or frame, where they ought to have 

 plenty of air at all times. In winter a temperature of 

 4.'i° F. suits them well, and they last much longer in 

 lilossom than if kept warmer. This Primrose is seldom 

 troubled with insect pests. Some of the best and most 

 distinct varieties are Russell's Queen of Whites, Alba 

 magnifioa, Princess Louise, Cheswick Red Improved, 

 Comet, Rubra superbissima. The best blue out of a 

 number we have tried is Farquhar's Improved Blue.
