A Dwarf 
Polemonium 
Polemonium confertum mellitum. 
The above plant is only 6 in. high 
hen well grown, and is notable for the 
eculiar form of the leaves. All of them 
rise from the rootstock, and each pinna 
r segment is again cut into three, and 
iese are all crowded together, ntaking 
ie whole leaf appear of a feathery 
aaracter. The ordinary or typical form 
as rich blue, funnel-shaped flowers clus- 
ired at the top of the flower stalk. The 
ariety under notice differs by having 
hite'flowers with yellow anthers. The 
lant is a native of north-west America, 
articularly on the Rocky Mountains, 
t is, therefore, well adapted for culti- 
ation on the rocker}', as it grows slowly, 
nd is not inclined to over-ru. its neigh- 
ours. It is perfectly hardy, although the 
ccompanying illustration shows a plant 
1 a pot which we photographed in the 
urserv of Messrs. Barr and Sons, Surbi- 
an, Surrey, on the 12th May. That will 
ive an idea of its time of flowering.

Evervone who knows plants at all is 
amiliar with our native \ arrow (A. Mille- 
olium) and the Sneezewort (A. Ptarmica) 
q some form or other. Coloured varie- 
ies of the former and double varieties of 
he latter are highly prized for cut flowers 
■r as hardy border plants. There are, 
lowever, numerous species as yet seldom 
een, except in botanical gardens and 
rood nurseries. Several of them are 
'ery pretty, however, and might be more 
argely employed for planting on the 
ockery for which the dwarfer ones are 
yell suited. 
That under notice is a native of Switzer- 
and, and is therefore particularly hardy. 
The leaves are small, deeply divided into 
mear segments and feather-like. They 
ire rather longer than those of the better 
inown A. umbellata, and of a silvery 
grey colour. The stems rise to a height of 
5 in., and bear numerous flowers in 
corvmbose clusters. These flowers, to 
give them a popular term, are of rela¬ 
tively large size for a plant of this dwarf 
habit. Indeed, they are much larger and 
more showy than those of A. umbellata 
to which it would appear to be more or 
less closely related. 
The plant is of easy cultivation if ele¬ 
vated on the rockery, so that it will be 
kept fairly dr}' during the wetter part 
of our^vear, and where it will be seen to 
advantage. It is too dwarf to plant in 
an ordinary herbaceous border, because 
it would soon get over-run by tall growing 
neighbours. It is also of easy propaga¬ 
tion, as large plants may readily be divi¬ 
ded into numerous pieces about the be¬ 
ginning of April, and planted out directly. 
Those who have only a small plant and 
wish to increase the number of specimens 
could take cuttings during July and 
August, placing them under a hand-light, 
kept closed until the cuttings show signs 
of having rooted by commencing to grow.
