Being found directly under tlie equa- tor, caladiums are distinctly tropical, and cannot be treated to too high a temperature. This is particularly true in greenhouse culture, and heat and moisture are the two essentials. The tubers can be started in January, but on an average better results can be obtained by starting them in February or the beginning of March. If they are started early in the season, they will be well grown in the early summer months and the foliage well developed and in a condition to stand exposure at that season. This also makes it possible to store the tubers away under the benches at that time in fall when all plants must be under glass, and the space occupied by caladiums is needed for winter flowering plants. This early start therefore has a twofold advantage. But those who have not a warm house commanding at least a temperature of 65° at night had better wait until later in spring when a good brisk heat is at- tainable. At the Missouri Botanical Garden the tubers are started about the second week in March and by the first week in June, the plants are in an excellent condition to transfer into the show house. They will be an fairly good condition by September, which ds an advantage, because there is nothing of value which could be used in place of caladiums at this time of the year. This method has been found more sat- isfactory than the one previously men- tioned. The tubers should be planted in various sized pots according to their dimensions and vigor. Some may re- quire a thumb pot while others may re- quire a 4, G or even an 8-inch pot. The pots must be well drained, as the plants require a copious supply of water, which, however, must not be al- lowed to stagnate about the tubers. When the pots have become well filled with roots the plants should be shifted from time t
