8 4 THE UNHEATED GREENHOUSE 



which their evergreen habit peculiarly fits them, as they are 

 never unsightly. The single and semi- double kinds are 

 by far the most interesting as well as ornamental, and there is 

 a charming little white species (C. Sasanqua alba) which is 

 well worth growing. 



When grown in pots, after they have made their new 

 leaves not before they should be plunged out of doors 

 in a semi-shaded position, which in their case is better 

 than full exposure to the summer sun, and they must be 

 carefully attended to with regard to watering. When it is 

 time to take them in, about October i, a gradual transition 

 from open air to frame, and from frame to greenhouse, will 

 generally overcome the dropping tendency. 



It is perhaps a little difficult to define the exact limits of a 

 hard-wooded plant, but speaking generally, it is one with 

 woody stem and somewhat wiry branches, and with fine hair- 

 like roots, which delight in a fibrous, peaty soil mixed with 

 sand. Of such plants a Cape Heath, or, for that matter, our 

 common Heather, may be taken as a type. There are a 

 good many shrubby subjects which may be said to take an 

 intermediate place, the successful management of which may 

 lead up to the more difficult New Holland and Cape plants. 

 Amongst these easier plants to grow, which are content with 

 good loam instead of peat, may be mentioned the Shrubby 

 Mimulus (M. glutinosus) with pretty salmon-buff blossoms of 

 the Monkey-flower type, of which there is also a noteworthy 

 crimson-red variety. One of the daintiest of the Calceolarias 

 (C. violacea) may also for convenience sake be placed in this 

 section. It may be grown out of doors ; in fact, in a Dorset- 

 shire garden under the shelter of a wall it grew into a good 

 sized bush, 2 ft. at least in height, and flowered abundantly 

 every season until an unusually severe winter killed it. 

 Neither its foliage nor woody habit, nor its pale-mauve helmet- 

 shaped flowers, are the least suggessive of any ordinary form
