THE FLOWER GARDEN. 
Thymus (Thyme). — The fragrant-leaved thymes, though 
usually associated with the kitchen garden, are by no means 
to be despised as flower garden plants. They are excellent 
plants for carpeting bare spots on sunny rockeries, slopes 
or borders. The Lemon-scented Thyme (T. Serpyllum citri- 
odorus) ; the Golden-leaved Thyme (T. Serpyllum citriodorus 
aureum) ; Woolly-leaved Thyme (T. Serpyllum lanuginosus) ; 
Fraser’s Silver Thyme (T. Serpyllum citriodorus argenteus) ; 
White Mountain Thyme (T. Serpyllum albus), white-flowered ; 
Crimson Mountain Thyme (T. Serpyllum coccineus), crimson- 
flowered ; Peppermint-scented Thyme (T. carnosus) ; and the 
Azorean Thyme (T. azoricus), are all deserving of a place in 
the flower garden. Besides being suitable for the foregoing 
purposes they are also adapted for carpeting small beds 
planted with choice bulbs. Being evergreen, too, their foliage 
is attractive all the year round. Plant in ordinary soil at any 
time. The golden and silver-leaved kinds should be increased 
by cuttings inserted in sandy soil in a cold frame in August 
or September ; the rest by division. The green forms may 
also be reared from seed in spring. 
Tiarella. (Foam Flower; False Mitrewort). — T. cordi- 
folia is a N. American perennial herb, belonging to the Saxi- 
frage order (Saxifragaceae). It grows about 6 in. high, has 
heart-shaped, hairy, reddish-bronze leaves and small creamy- 
white, starry flowers borne in erect feathery plumes resembling 
a wreath of foam. The flowers appear in April, and render the 
plant an interesting and pretty object when in full bloom. 
It will succeed in ordinary soil in a partially shady border or 
on a rockery. Plant in autumn or spring, and lift and divide 
every two years. Increased by division. 
Trachelium (Blue Throatwort). — T. cseruleum is a very 
pretty perennial, of Italian origin, and a member of the 
Harebell order (Campanulaceae). It grows i to 2ft. high, and 
bears large clusters of small blue flowers in summer. There 
is a white form of it named album. When in flower the plant 
is a very beautiful object. It likes a warm sheltered position 
and a well-drained sandy loam, freely mixed with leaf-mould. 
Plant in spring. Increased by seeds sown in gentle heat in 
March, the seedlings being grown on and hardened off in 
May, then planted out in June; also by cuttings of the young 
shoots in summer. 
Trachymene. — T. cmrulea, also known as Didiscus 
cseruleus, is a very pretty half-hardy annual, growing 1 to 2ft. 
high, and bearing blue flowers in umbels in late summer. 
This species is a native of W. Australia, and a member of the
