27S THE TLORAL WORLD AND OAEDEN GUIDE. 



JPentstemon crassifolius^ the Thick-leaved Pentstemon. — Neat 

 evergreen shrubby habit, with pretty blue flowers in May ; a dis- 

 tinct and excellent plant, 



' Phlox fi'ondosa^* the Leafy Phlox. — Is another good one ; but 

 second to none is sZ(^5?^Z«zf«,* which on rockwork is sometimes "all 

 flower.'* It may be used with great advantage, too, in small beds 

 for the spring garden. 



Fhlox JVehoni, Nelson's Phlox. — "White, with lilac eye ; dwarf 

 and massy in habit, and hardy ; an exquisite little plant. 



Phlox verna, the Spring Phlox. — Another choice thing among 

 dwarfs ; it grows, however, from four to six inches high, generally 

 about twice as tall as P. Nelsoni. 



Primula auricula* — The common Auricula of sorts, if grown as 

 well in gardens as it is often to be seen (comforted with tea-leaves) 

 down areas, etc., in London, would be very useful, as indeed it already 

 is in many places. 



Primula vulgaris plena var.^ — The varieties of double Primula — 

 white, purple, lilac, sulphur, and violet — when well grown, almost 

 bear away the palm among spring flowers. But they are difficult to 

 get now — at least as much so as old mutton ; and those who have a 

 stock would do well to increase and preserve it. In some pleasant 

 country places, where cottage gardening is much practised, some of 

 the best varieties might be easily picked up. 



Pritnula polyanthus* is of easier growth and more easily raised 

 than either of the foregoing, and, as there are many beautiful 

 varieties, it should be extensively used, especially in shady borders, 

 etc. 



Ptarmica, or Achillea Clavennoe, is a first-class silvery-leaved 

 plant, useful for edgings, etc., in the summer garden, and useftd 

 also in spring, as it is hardy, and produces white flowers in May. 



Pyrethrum roseum* the Eosy Feverfew. — Some of its many fine 

 varieties, single and double, are well worthy of cultivation. 



Panunculus aconitifoliu^^fl.ioleno, the Aconite-leaved Buttercup, 

 native of Europe, " The fair ladies of Prance." — Yery pretty white 

 double ; does beautifully in moist and rather shady places. 



Panunculus ac7ns, fl. pleno, double-flowering Acrid Crowfoot. — 

 Pretty showy double yellow, easily grown. 



Panunculus amplexicaulis, the Plantain-leaved Buttercup, native 

 of the Pyrenees. — Pine white kind, very distinct in leaf and habit; 

 dwarf. 



Pondia epipactis. — A charming thing for its yellow disks in early 

 spring. 



Baponaria ocyriicides and pulchella^ Perennial Soapwort, — Both 

 useful, pink-flowering plants, well suited for rockwork, etc. 



Saxifragas.* — Many; say pyramidalis, Andreivsii, and Stans- 

 ■fieldii for a beginning. 



Scilla camjjanulata and >S'. liyacinthoides, Bell and Hyacinth 

 Squills. — Larger and later than the following. 



Scilla Siberica* and trifolia, the Siberian Squill. — The two best 

 dwarfs. 



Silene acaulis, the Stemless Catchfly, native of Britain, and
