of the best for pot culture, and requires the protection of a 

 frame or greenhouse. The compost for it should be loam 

 from rotted turfs one-half, dung from a spent hot-bed one- 

 fourth, and turfy peat one-fourth, Well mixed together. Se- 

 lect a small healthy plant, place it in a four-inch pot, and 

 grow it in a frame : if it should throw up a stem for bloom, 

 take off the top at once ; and when the pot is full of roots, 

 change it for a six-inch pot, using the same kind of compost. 

 Thus continue to grow it, changing the pot for a larger as 

 fast as the roots fill up the one it is in. The second season 

 it may bloom ; but continue the changing into larger pots, 

 and, when it is three years old, it will produce many spikes 

 of bloom, which should be spread fan-like on a trellis, and, 

 in this state, it completely covers a fireplace or a window 

 with its numerous beautiful blue flowers. The smaller per- 

 ennials make beautiful rock-plants.
