PLATE 13. 
TROLLIUS EUROP/EUS GRANDIFLORUS. 
The Globe Flowers or Globe Buttercups—names by which members of 
the genus Trollius are popularly known—are beautiful and strong-growing 
perennials that should find a place in every garden of any pretensions. 
They are fine bushy plants with ornamentally divided leaves, the green of 
which forms a beautiful contrast to the rich yellow or orange-yellow 
blossoms. 
The subject of our plate is a particularly fine variety of the Mountain 
Globe Flower or Golden Ball that flourishes naturally in sub-alpine pastures 
and copses. Under cultivation it succeds well in any good garden soil, 
but prefers a deep rich and moist loamy soil such as may be found near 
the margin of ponds, lakes or streams. Indeed in such situations the 
Globe Flowers look particularly ornamental and grow in greater luxuriance 
than in any other position. The plants often reach a height of 2 feet, 
and disp]ay their large flowers during the early summer months, and often 
a second time in September and October—especially if those first produced 
have been freely cut. 
Other Globe Flowers worthy of cultivation are T. asiaticus , an Asiatic 
species with several good forms such as Fortunei, and Orange Globe; 
T. acaulis , a dwarf Himalayan species ; T. altaicus , T. caucasicus , and 
T. americanus (or laxus ), the last-named being an American plant with 
pale greenish-yellow flowers. 
The Globe Flowers are easily increased by dividing the root-stocks 
about September or not later than October, or in mild showery weather 
in spring. The early autumn, however, is the best time for disturbing 
the plants, as the cold, drying winds are often detrimental to plants 
that have been moved in spring. Seeds may also be sown as soon as 
ripe, but it usually takes 2 or 3 years before good sturdy flowering plants 
are obtained in this way; and in the case of particularly fine varieties, 
there is a danger of deterioration to poorer forms. 
THE GENUS CROCUS. 
For several weeks past, beginning with the issue for Feb. 15, Mr. 
S. Arnott has been reviewing the genus Crocus in the pages of the 
“ Journal of Horticulture.” Mr. Arnott is a well-known authority on 
bulbous plants generally, and his enumeration of the various species of 
Crocus will form an excellent addition to what is already known of the 
genus from Dean Herbert, Mr. George Maw, and Mr. J. G. Baker. 
There are many species of Crocus and almost innumerable varieties, 
and it is by no means an easy matter to settle the nomenclature, as it 
is in many cases difficult to decide whether certain forms should be 
distinct species or only varieties of some other species. Mr. Arnott is 
describing species and varieties in detail, giving their native habits,, 
altitudes, and other useful information.
