Gardeners and Florists’ Annual for J9I8 
shoots, young Horse Kadish leaves, Marsh Marigold (sometimes called 
American Cowslip), Poke Sprouts, Pepper Cress, Purslane or “pussley,” 
and in the Southwestern States some sorts of cactus leaves and stalks. 
If the bitter or acrid flavor is too strong, as is frequently the case with 
Horse Kadish leaves or Poke Sprouts, for example, it may be lessened 
by changing the water once or twice during cooking. Rightly cooked, 
all of the plants mentioned are harmless. Marsh Marigold is sometimes 
employed, also Water Cress, Pepper Cress, Nasturtium and the young 
leaves of Dandelion. 
Potatoes, Treatment of for Scab and Rosette. — Soaking seed 
Potatoes for 1% hours in a solution of 4 oz. of corrosive sublimate 
mixed in 30 gallons of water, or for 2 hours in a solution of 1 pint 
of 40 per cent, formaldehyde (formalin) mixed in 30 gallons of water 
will control scab and rosette diseases, according to specialists at the 
Ohio Experiment Station. The Potatoes should be soaked before cut- 
ting, and if not used soon afterward should be spread out to dry. 
Sacks or crates used for handling or storing treated Potatoes should 
be disinfected with the same solution. The corrosive sublimate is a 
deadly poison and should be kept from children and animals. 
Potassium Sulphide (See Fungicides). 
Pots, Standard Flower. — There is very little to be said regard- 
ing one of the most common articles about the greenhouse, namely, the 
plant pot. A standard flower pot is one in which the inside diameter 
at top, is the same dimension as its depth, the sides being made at a 
78 deg. angle as adopted by the convention of the S. A. F. in 1890. 
The sizes run from 1 inch to 14 inches, and 
in one-half sizes from 2yg inches to SYs inches 
inclusive, with also 1% inches to inches, 
and 3% inches, known also as 4A, and used 
by many instead of the standard 4 inch pot. 
A good pot is one which has a clean pot-red 
color, very porous, very tough, and not too 
thin, as a thin pot dries out very rapidly. 
It ought also to have a substantial rim, which, 
in the larger sizes, serves to give a hold, pre- 
venting slipping. Azalea pots, sometimes 
called two-third pots, are about 1 inch less 
in depth than the standard pots, and are in 
demand for stock which does not require a 
large amount of room for roots, and by some 
growers for tall or bushy growing stock, be- 
cause it furnishes a neater looking plant when 
established. The bulb or seed pan, called also 
the half-pot, is one half the depth of the stand- 
standard Sizes of Flower ard pot and is used for bulb stock. Pots as 
Pots manufactured, must necessarily be of various 
degrees of burning, and tastes as to burning 
vary as much as men. The best “burn” for average indoor use is that 
known as “medium burn,” while for outdoor use during Winter, the 
“hard burn” pot is not so liable to crack from heavy frosts. Pots take 
up moisture to a degree equal to the hardness of “burn.” A soft, light
