in shrubbery or woodland borders, or in rough corners of the 
garden. It will thrive in ordinary soil and soon spread into 
a large mass. Plant in autumn. Increased by division. 
Phacelia. — A genus of hardy annuals, belonging to the 
Nemophila order (Hydrophyllaceas). Few of them are worth 
growing except in wild gardens or shrubbery borders. The 
most attractive are : P. campanularia, blue, gin. ; P. Parryi, 
violet-blue, gin. ; P. tanacetifolia, pale violet, 2ft., a useful 
bee plant; and P. Whitlavia (Syn. Whitlavia grandiflora), rich 
blue, Sept., ift., and P. Whitlavia alba, white. Sow seeds in 
April where required to grow and thin out later to a foot apart. 
Natives of California and summer flowering. 
Phlomis (Jerusalem Sage). — Hardy shrubby and herba- 
ceous perennials, belonging to the Lavender order (Labiatae). 
The following species are handsome plants for mixed sunny 
borders : P. fruticosa, a shrubby species, with grey downy 
foliage and rich yellow flowers borne in whorls in June and 
July; height 3ft.; native S. Europe. P. herba-venti, a S. 
European species, growing 2ft. high, and bearing purplish- 
violet downy flowers from July to October. P. viscosa, a 
native of Syria, and bearing yellow flowers in summer ; height 
3ft. The last two are herbaceous. Grow in light sandy or 
ordinary soil in sunny borders and plant in autumn or spring. 
Increased by seeds sown outdoors in April ; P. fruticosa by 
cuttings in cold frames in summer ; herbaceous ones by divi- 
sion in autumn or spring. 
Phlox. — Half-hardy annuals and hardy herbaceous and 
evergreen perennials, belonging to the Nat. Ord. Pole- 
moniaceas), and natives of America. The only annual 
species is P. Drummondii. Of this beautiful, free- 
flowering and showy half-hardy annual there are many 
lovely varieties or strains, with flowers ranging through 
all ^shades of crimson, scarlet, pink, white, yellow 
and salmon. A charming race of plant for grouping in borders 
or massing in beds. They vary from gin. to i8in. in height, 
and bear single, round, or fringed, or pointed petals ; there 
are also double varieties. Quite a number of distinct varieties 
or strains will be found in trade lists, the best perhaps being 
the grandiflora strain. They are easily reared from seed sown 
on a hot-bed, or in shallow boxes of light soil in a warm 
greenhouse in March. When the seedlings have formed their 
third leaf, carefully transplant them 2 to 3m. apart in boxes, 
grow on in heat till the beginning of May, then harden off 
and plant out at the end of May. To ensure good bushy, free- 
flowering plants, pinch out the points of the main shoots 
when 3in. high. These phloxes require a rich soil and a sunny
