ugUSt.~] GREEN-HOUSE REPOTTING, &C. 



OF REPOTTING PLANTS. 



Any of the plants enumerated in March under this head 

 may be now done according to directions therein given, 

 and which apply to all sizes. This is the proper period 

 for repotting the following : 



Calla, a genus of four species. None of them in our 

 collections, and in fact not worth cultivation, except C. 

 sethiopica, Ethiopian Lily, which is admired for the purity 

 and singularity of its large white flowers, or rather spatha, 

 which is cucullate, leaves sagittate. It is now called Rich- 

 ardia sethiopica. The roots, which are tubers, should be 

 entirely divested of the soil they -have been grown in, 

 breaking off any small off-sets, and potting them wholly in 

 fresh earth. When growing they cannot get too much 

 water. The plant will grow in a pond of water, and with- 

 stand our severest winters, provided the roots are kept at 

 the bottom of the water. 



Cyclamen. There are eight species and six varieties of 

 this genus, which consists of humble plants with very 

 beautiful flowers. The bulbs are round, flattened and solid, 

 and are peculiarly adapted for pots and the decorating of 

 rooms. C. count, leaves almost round ; flowers light red ; 

 in bloom from January to April. C.persicum, with its four 

 varieties, flower from January to April ; colour white, and 

 some white and purple. C. hederssfdlium, Ivy-leaved ; 

 colour lilac ; there is a white variety ; flowers from Sep- 

 tember to December. O. Europseum, colour lilac, in bloom 

 from August to October. C. neapolitanum, flowers red, in 

 bloom from July to September. These are all desirable 

 plants. When the foliage begins to decay, withhold the 

 accustomed supplies of water, keeping them in a half dry 

 state ; and, when growing, they must not be over- watered, 

 as they are apt to rot from moisture. Keep them during 

 the summer months in partial shade. The best time for 

 potting either of the sorts is when (he crown of the bulb 

 begins to protrude. If the pots are becoming large, every 

 alternate year they may be cleared from the old soil, and 

 put in smaller pots with the crown entirely above the 

 ground. When the flowers fade, the pedicles twist up like 

 a screw, enclosing the germen in the centre, lying close to
