LIST OF FLOWERS 



kinds are more showy, and of the named sorts some of the best are: 

 Belzebuth, dark crimson; Dr Andry, scarlet and yellow; Phoebus, 

 rich yellow; and Fenelon, orange and scarlet. Among the dwarf 

 Alpine species the following may be quoted: P. alba, with pretty 

 white, star-like flowers; P. pyrenaica, with large flowers of deep 

 yellow; and P- tonguei, with unusual coloured flowers, orange and 

 terra-cotta. Potentillas are, for the most part, quite hardy and may 

 easily be raised from seed; they thrive in a light soil and luxuriate in 

 plenty of sunshine. 



PRICKLY POPPY. See Argemone. 



PRICKLY THRIFT. See Acantholimon. 



PRIMROSE. This hardy perennial (the Primula vulgaris) is 

 too well known to need description here, but it may not be amiss to 

 mention that we have now some beautiful strains which range in 

 colour from pure white through many shades of crimson, maroon, 

 orange and yellow. AU may be raised from seed sown in the open in 

 some shady patch of ground during June or July, and it is wise to 

 give a protection from slugs by a sprinkling of soot or wood ashes. 

 As soon as the seedlings are strong enough to bear removal they 

 should be transferred to the place where they are intended to bloom, 

 which should be a spot tempered from the fierce heat of the sun and 

 with soil of stiff, moist loam. For the Rock Garden the Alpine Prim- 

 roses are very valuable; such as Primula rosea, a Himalayan species, 

 with compact tufts of pale-green leaves from which emerge flower- 

 stems 6 or 7 inches high, bearing flowers of delicate pink, and of 

 hardy and vigorous growth; while Primula denticulata is equally _ 

 hardy and of more robust growth, being some 9 or 10 inches high, 

 with stout stems terminating in fine clusters of lilac blossoms. 

 Primula viscosa, with its flowers of rosy-purple, and Primula farinosa, 

 with flowers in shades of lilac, pink and crimson, should also be 

 mentioned. 



PRIMULA-AURICULA. See Auricula. 



PRIMULA-SINENSIS {Chinese Primrose). The genus Primula 

 embraces many flowers which are usually called by other names, such 

 as Auricula, Primrose, Polyanthus, etc., but the Primula of common 

 parlance is the Primula-Sinensis in its many varieties. Under the 

 protection of the greenhouse it is hardy enough, but though some- 

 times classed in seed catalogues as a perennial it is more wisely 

 treated as an annual. Successive sowings may be made from April
