EEPORT ON CACTUS DAHLIAS, 1900. 
A COLLECTION of 146 stocks of Cactus and Decorative Cactus Dahlias 
was planted in June in good, well drained ground, the distance between 
the plants being about 4 feet each way, the object being to discover the 
varieties best adapted for border culture. 
On account of the very hot dry weather in July, the plants made little 
growth until August and September ; the first-named month being un- 
usually wet, vigorous growth ensued which seemed likely to be at the 
expense of the flower, but from the end of September to the early part of 
November many of the plants were literally smothered with blossoms, 
especially the varieties named 'Exquisite,' 'King of Siam,' 'Orange 
Glare of the Garden,' ' Alfred Vasey,' ' Mrs. John Goddard,' ' Sunshine,' 
' J. E. Frewer,' 'Night,' ' WiUiam Cuthbertson,' 'Britannia,' 'Dr. 
Jameson,' ' Countess of Lonsdale,' and ' Salisbury White.' 
The Floral Committee examined the collection upon two occasions 
and Highly Commended thirty varieties.
