asperula suberosa. 
Very few of the species of Woodruff are in general cultiva- 
j tion. If we except the very common Asperula odorata and A. 
azure®, the annual species with pale blue flowers, we may be 
said to have exhausted the list of species that are at all well 
known to gardeners. During the past few years the Dyer’s 
Woodruff (A. tinctoria) has made its. appearance in private 
gardens, and was brought up at a. meeting of the Royal Hor¬ 
ticultural Society last year, if we remember rightly. Our 
other native species—namely, A. cynanchica—is cultivated in a 
few places, chiefly botanic gardens. That which we have under 
notice we may compare to the last-named in the matter of 
size, but in all other respects it is totally different. 
A. suberosa is a native of Greece, and forms a dense tuft of 
slender stems about 3 in. to 6 in. high, or possibly longer under 
certain conditions of cultivation. If it were not for the large 
them entirely successful will find this plant an acquisition and 
indispensable, for we consider it. simply charming. 
ONOSMA ALBO-ROSEUM. 
The above species was first mentioned in the “ Garden and 
Forest” in 1890, page 523, and this date may be considered 
as that of its introduction to cultivation. It is a native of 
Asia Minor, and would seem to require a drier situation than 
that in which 0. echioides succeeds. The oblong leaves are 
thickly covered with shaggy hairs, which give the plant, a gray 
appearance. The name may be somewhat puzzling to readers, 
and apparently contradictory, but when the flowers first expand 
they are white, and after a. few days change to. carmine-rose of 
a greater or less; intensity of colour, and to blue when fading. 
When a. plant has been in bloom for a. little time, the two. or 
three colours are present together and lend interest to the 
plant by contrast. 
Asperula suberosa : flowers pale pink. 
number of stems, they would fall about loosely if they attained 
any height, but the number of them forms a dense cushion 
supporting one another. The very short and small leaves are 
in whorls of six, and are densely hirsute, giving the whole plant 
^ a gray appearance, especially when out of bloom. The flowers 
themselves are very freely produced in clusters at the ends, of 
the stems, and have a. long funnel-shaped tube and shortly four- 
lohed lamina, and, on the whole, resemble a Bouvardia, in 
miniature. 
It is the character of an Asperula. to have a funnel-shaped 
corolla, but no species that has yet come under our notice has 
so 1 long a flower as A. suberosa, which has been under our 
notice for some years past at Kew, where our photograph was 
taken from a. plant in the Alpine House. It has been grown 
for some years in pots, a.nd may not be so hardy as the others 
above mentioned, but it is certainly worthy of a little trouble 
on, account of its neat and beautiful habit and delicately-col¬ 
oured flowers, produced in great profusion. Those who have a 
collection of plants in pots which require a cold frame to make 
The species of Onosma, belong to the Borage family, and are 
very characteristic of a. large number of plants belonging to 
that family, and with which we are. more or less familiar in 
gardens. The photograph was taken in the rockery at Kew, 
where a. large plant, has taken full possession of a rather dry 
spot facing the south and under the shelter of a, W eymouth 
Pine. It would be too. much at, present to predict that it will 
be perfectly hardy in this countiy, seeing that we have had no 
lard frosts since it was planted at Kew ; but if a dry situation 
is selected for it and the foliage kept, fairly dry in winter¬ 
time it may stand a. deal of cold. Hardy plantsmen could 
always take the precaution to have a, few young plants in. pots 
■or wintering in a cold frame, by way of reserve. Possibly 
,1sO' the plant may produce seeds, and could be multiplied in 
:hat way.
