TENDER BORDER AND BEDDING PLANTS. 349 
they tequire generous treatment. They must be carefully 
grown from the first, and the soil be deep and rich to 
promote and maintain a healthy growth. Dig in plenty of 
rotten manure in spring, and choose a warm sheltered position 
for growing the plants. Sow the seeds thinly in a light com- 
post in gentle heat at the end of March, and as soon as the 
seedlings are an inch high transplant them singly into small 
pots. Grow on a shelf near the glass until May, then harden 
off and plant out at the end of May 8 to iein. apart. Plant 
out in showery weather if possible ; if not, water freely. Hoe 
the soil carefully between the plants, and when new growth 
begins actively give a dusting of guano occasionally in showery 
weather. Seeds may a'so be sown outdoors in May. In this 
case sow two or three seeds at intervals of a foot, and when 
the seedlings appear, reduce them to one in each place. The 
following are good all-round varieties : Z. elegans, single, 
mixed colours, 2ft. ; Z. elegans flore pleno, double, various 
colours ; flore pleno alba, white, double ; flore pleno aurea, 
yellow or orange, double ; flore pleno coccinea, scarlet, double ; 
flore pleno rosea, rose, double ; flore pleno violacea, violet- 
purple, double ; pumila flore pleno, dwarf, double, various ; 
pumila flore pleno alba, dwarf, double, white ; pumila flore 
pleno coccinea, dwarf, double, scarlet ; robusta flore pleno, 
tall, various, 2|ft. ; robusta flore pleno, double, white ; robusta 
flore pleno coccinea, double, scarlet. Z. Haageana is a dwarf 
orange, single species growing 6in. high, and flore pleno is a 
double orange form of it. Natives of Mexico and members of 
the Daisy order (Compositae). 
Waitzia — Half-hardy annuals, belonging to the Daisy 
order (Compositae), and natives of Australia. Their flowers are 
valuable for cutting and drying for winter decoration, as in the 
case of other “Everlasting” flowers. The two best species 
are W. aurea, bright yellow, i8in. ; and W. grandiflora, yellow, 
i8in. Both flower in August. Sow seeds in gentle heat in 
March, harden off the seedlings and plant out a foot apart in 
ordinary soil in sunny borders late in May. 
Wigandla. — Tropical half-hardy perennials, with hand- 
some foliage, used chiefly in large gardens for intermixing 
with other foliage plants for summer bedding. The chief kinds 
used for the purpose are W. imperialis, 5ft. ; W. macrophylla, 
10ft. ; and W. Vigeri, 6 to 8ft. All have large leaves and form 
handsome plants. Easily reared from seed sown in a tempera- 
ture of 75 deg. in spring, grown on in pots, and planted or 
plunged out in the beds in June. Young plants may also be 
reared from cuttings in heat in autumn. Nat. Ord. Hydro- 
phyllaceae (Nemophila family).
