Lillium candidum and L. longiflorum may be 
given the same treatment but will require a longer 
time in which to mature. 
Calla (Richardia Aethiopica) The soil for 
callas should, where possible, be about one-third 
rotted cow manure. Otherwise make very rich soil 
with bone and whatever may be had but get the cow 
manure if possible. It also likes a great deal of 
water. Pot at once in large pots, give a thorough 
watering and keep cool and shaded for four or five 
weeks, until active growth begins. Then give more 
heat, keeping it about 60 degrees if youcan. They 
will continue to bloom a long time. In the spring, 
after flowering ceases, dry off gradually and lay

until August. Beside the large white calla most 
commonly seen, there are several other forms which 
will be found described in good catalogues, among 
them Tom Thumb or Little Gem, a dwarf sort; El- 
hottiana, the Yellow calla; Godfrey, a dwarf ever-

Cyclamen. While these beautiful flowers may

former, pot in four- or five-inch pots, using a light
