- THE - 
Dwarf Convolvulus. 
/ 
(Convolvulus tricolor). 
The name of this most commonly em¬ 
ployed in the catalogues of seedsmen is 
Convolvulus minor, that is, the smaller 
Convolvulus. This applies to the dwarf 
habit of the plant rather than to the flower, 
for the latter is, indeed, of large size. The 
true name is C. tricolor, for in most 
of the forms three colours may be found 
in every bloom. The larger and outer 
portion of the flower is usually of some 
shade of blue or purple. A broad zone 
surrounding the centre is usually white, 
and the eye, or centre, is dark yellow, 
thus giving the three colours. There is 
a white variety in cultivation, however, 
which has only a yellow eye to the white 
flower. 
raising which the half hardy annuals do. 
Although it belongs to the Convolvulus 
family, it does not twine, neither do the 
roots, or rather undergnound stems, creep 
through the soil. There is no danger, 
therefore, of introducing what may prove 
to be a bad weed in the garden. It dies 
away entirely after it has ripened seed. 
The plant is of weak and rather spreading 
growth, and therefore may not suit every 
situation or garden, but its dwarf habit 
will enable it to be grown in the smallest 
of gardens without inconvenience. 
The best way of growing it is in the form 
of a patch or clump. A bed may be filled 
with it entirely by those who have the 
space at command. The routine of cul¬

Those who contemplate growing this

of sunshine, and during the heat of the 
day may be seen at their best.

. • A FINE . . 
Wolf’s Bane. 
(Doronicum plantagineum excelsum). 
Within recent years a considerable 
amount of attention has been given to the 
various known species of Wolfs Bane, but 
none of them have 'been so widely culti¬ 
vated or in such quantity as the subject 
of this note. Besides being grown in pri¬ 
vate gardens of every degree, it has also 
been taken in hand by the market gar¬ 
dener, and put upon the market in con¬ 
siderable quantity during the spring 
months. It flowers in spring, earlier or 
later according to the conditions under 
which it is placed. The shelter of a frame 
enables it to come on early if flowers are 
desired for cutting. These are of a bright 
yellow colour, and by some people are 
termed Yellow Marguerites, though flowers 
in any way resembling a Chrysanthemum 
or Ox-eye Daisy may be termed a Mar¬ 
guerite. 
The plant has flesh)- or slightly tuber¬ 
ous roots, and is of the easiest cultivation 
in any good garden soil, but, like many 
other herbaceous plants, it repays the 
trouble of liberal treatment. As the un¬ 
derground stems extend rapidly and soon 
occupy the ground- the best results are 
obtained by transplanting some of the 
younger crowns at frequent intervals. 
This may be done either in March, early 
in April or again at the end of Septem¬ 
ber. The last is certainly the best time 
as it enables the plants to get well estab¬ 
lished before winter and ready to flower 
in early spring.. No plant rewards the 
cultivator better for attending to its likings 
in this respect.
