102 THE UNHEATED GREENHOUSE 



the greenhouse, is Stokesia cyanea, a fine composite, with 

 blue Thistle-like flowers. There are two varieties a fact 

 which has only recently been made known and as one of 

 these is summer-flowering, care should be taken to get the 

 right sort for late work. Aster grandiflorus, the latest of the 

 Michaelmas Daisies, is sometimes treated in the same way, as 

 it seldom perfects its large blue flowers in the open border. 

 Senecio pulcher is a good late-blooming Groundsel, with red- 

 purple flowers, which may be put into the same list. It is 

 interesting to grow it from inch-long root-cuttings in early 

 autumn, like Seakale, thus securing fresh plants every year, 

 and the best effect is made when several plants occupy a 

 broad, deep pan to form a clump. The colour of the flowers, 

 unfortunately, is one that contrasts badly with most others, 

 which is a drawback. A very good low-growing plant belong- 

 ing to the same genus, Senecio Ksempferi, may be mentioned 

 here, though it is somewhat more tender. It has broad, 

 handsome foliage, splashed with white and a touch of pink, 

 and is worth growing both for its leaves and flowers. It 

 bears a loose cluster of large yellow Daisy-like flowers, and is 

 more often seen in Belgium and elsewhere on the Continent 

 as a window plant than with us. This is not to be confused 

 with Farfugium grande, with round yellow spots on its green 

 Coltsfoot-like leaves, which is, perhaps, a greater favourite 

 with English folk than it need be. 



Chrysanthemum serotinum, better known amongst her- 

 baceous perennials as Pyrethrum uliginosum, rears its great 

 height and holds up its flowers high above our heads in the 

 autumn garden, unless the precaution is taken of heading 

 down the plants in early June. These tops may be put in as 

 cuttings and make excellent little pot plants, proving very 

 useful in the greenhouse during October and November. 

 The Winter Cherry, Physalis Franchetti, is striking and 

 handsome for late autumn when grown with several stems
