and housed, or sheltered by a frame from sharp 

 frosts. This flower is properly a perennial^ (see list 

 IV.) but as it is apt to be cut off in severe weather, 

 it is here considered as biennial, and may take its 

 chance after the first flowering. It is sometimes 

 made an annual of. See colutea, list VII. 



Snap dragon we consider as biennial, it not blow- 

 ing so handsome afterwards. The variegated (as all 

 stripes are) is tcnderish; this must be propagated 

 from cuttings, as indeed the plain may be, though 

 the finest plants come from seed. This flower is of 

 longest continuance in a poor soil, and will grow and 

 flourish out of cracks in old walls. 



Stocky or stock gilliflower, brompton. Sec. is apt to 

 get too rampant before winter, and when killed by 

 frost, it is chiefly owing to this circumstance ; for 

 nothing stands severe weather well-, that has grown 

 very freely. Hence it is used to be the custom of 

 florists to transplant them several times in the sum- 

 mer ; (even at every full moon) but to keep them 

 down, and hardy, by this means, tends directly to 

 weaken the blow, if not to kill the plant. The most 

 reasonable method in this business is, not to sow too 

 early, (or before the first week in April) to thin 

 them, and to prick them out in time, that they may 

 not be drawn up long legged ; and by no means to 

 let them have a dungy soil to grow in, or a very rich 

 one. Prick them out the first cool weather after they 

 have six leaves, at six or eight inches asunder, where 

 let them remain till August^ choosing a showery 

 time, (rather about the middle) to plant them out 

 where they are to blow; but let not this be into a 

 moist soil, or damp situation : It is a good way to 

 mix half sand in the mould that lies about the 

 shanks above the roots ; and when wet and frost 

 comes, to lay coarse, or drift sand, round about 

 them, three or four inches high, which remove at
