HARDY PLANTS.

semi-double, Sept, and Oct., 4ft. ; Miss Willmott, semi-double, 
5 to 6ft., July to Oct. In connection with the annual species 
we should have mentioned H. argophyllus, a species with 
silky foliage and small yellow flowers, 5ft. ; H. cucumeri- 
folius, small yellow flowers with dark centre, useful for 
cutting, 3ft. ; and its varieties, Diadem, pale lemon, dark disc ; 
and Excelsior, deep yellow, twisted petals, pretty for cutting. 
The annual species may be raised from seed sown in the open 
garden in April, or in slight heat in March, and planted out 
in May. The tall Russian Giant kind makes a good temporary 
screen, and the rest may be grown in groups in the wild 
garden. For large borders where there is plenty of space 
few plants will yield a braver display of colour in autumn 
than these plants. Plant in autumn or spring. Any ordinary 
soil and sunny position will suit them. The plants should be 
lifted, divided and replanted every two or three years, other- 
wise they will soon overrun the borders. Increased by seeds 
sown, also by division of the roots in autumn or spring. 
Helipterum. — A genus of half-hardy annuals, belonging 
to the Daisy order (Compositae). Three species are cultivated, 
and all are natives of Australia. They bear scaly or chaffy 
flowers, which possess the property of drying and maintaining 
their natural shape, and thus becoming valuable for cutting 
and preserving for winter decoration. H. humboldtianum 
(Syn. H. Sandfordi) grows i8in., and bears bright yellow 
flowers, which assume a greenish tint when dry. H. Manglesi 
(Syn. Rhodanthe Manglesi) grows 16 to i8in. high, and bears 
rosy-pink flowers with yellow centres. H. roseum (Syn. Acro- 
clineum roseum) grows i8in. high, and bears rosy flowers. 
Album is a white, and grandiflorum a large rose variety of 
the latter. For preserving, gather the flowers when just fully 
expanded, tie them in small bunches and hang them head 
downwards in a cool, dry shed for a week or so. Seeds should 
be sown in heat in March, the seedlings transplanted into 
pots or boxes, hardened off and planted out late in May. May 
also be sown in the open border in April. Grow in masses in 
a sunny border in good ordinary soil. 
Helleborus (Christmas Rose; Lenten Rose). — Hardy 
perennials, belonging to the Crowfoot order (Ranunculaceae), 
and highly prized for their value for flowering in winter. The 
Hellebores are divided into two sections, one the Christmas 
Rose, which flowers from Christmas onwards, and the other 
the Lenten Rose, which blossoms from January to April. H. 
niger (Christmas Rose) is the best known species. This bears 
white flowers from December to March. Angustifolium is a 
narrow-leaved form of it, and two other notable varieties are
