IMPATIENS 



IMBRICATED. Leaves, sepals, &c., are said to be 

 imbricated when one laps over the next, and so in suc- 

 cession, like the tiles of a house, as in the leaves of the 

 common Heath, or Ling, Callu'na vulga'ris. 



IMPA'TIENS. Balsam. (From impatiens ; referring 

 to the elasticity of the valves of the seed-pod, which dis- 

 charge the seeds when ripe, or when touched. Nat. ord. 

 Cranesbills [Geraniaceae]. Linn. s-Peniandria, i-Mono- 

 gynia.) 



Hardy annuals and biennials, by seed in the open 

 border, in April. Scapiflo'ra, a bulb, requires stove heat, 

 and to be kept almost dry in winter. Greenhouse annuals 

 and biennials merely require to be sown in a hotbed in 

 March, and planted out as half-hardy and tender annuals. 

 All these may be kept over the winter by taking off 

 cuttings in the beginning of autumn, which would bloom 

 in the house early in the spring. See BALSAMS.

Culture of the Balsam. In years gone by the double 

 varieties of the common Balsam (/. Balsami'na) were 

 cultivated extensively for exhibition purposes, and no 

 class excited a keener competition in many parts of the 

 country. Good strains of seed were obtained and sown 

 in heat some time in March. As soon as the cotyledons 

 were fully developed the seedlings were potted off singly 

 in deep thumb pots, so as to get the stem buried to the 

 base of the seed-leaves to prevent legginess, which was 

 always regarded as a sign of bad cultivation. Light, rich 

 soil was used, and the pots were plunged in the hotbed 

 of a well-lighted stove. The temperature was kept at 

 70 to 75, and allowed to run up to 80 at closing time. 

 Plenty of top air was given, whenever the weather con- 

 ditions favoured, to prevent drawing, to which the 

 Balsam is very liable. As soon as the roots were well 

 round the sides of the pots, the plants were shifted into 

 larger sizes, giving them heavier and richer soil at each 

 shift. A flower or two was allowed to bloom on the 

 main stem to ascertain the quality, after which all the 

 inferior ones were thrown away or used for greenhouse 

 decoration. As the side branches developed they were 

 carefully staked out or tied down to a circular wire to 

 encourage repeated branching and form the foundation 

 of large plants. All flower buds were removed as fast 

 as they made their appearance, as this encouraged
