of two or three years. Spanish iris and also the English iris will,under ideal conditions of soil and cultivation, continue to develop newbulbs and to multiply. For this reason they can be left in the groundduring a number of years. In cutting flowers from bulbs it is quitenecessary that some leaf surface should remain after the flower stalkhas been removed. This leaf surface provides a "stomach" for theplant, in which digestive functions continue and new food is supplied to the bulb for the purpose of enlarging it and for the purpose of forming new bulblets. The gladiolus is the best example of bulbs which arereproduced in the average garden by new bulblets. Many varieties ofgladioli, however, will not reproduce bulblets if the flowers are re-moved. None of the varieties of the gladiolus will produce newbulblets or make strong bulbs if, when the flowers are cut, all of theleaves are removed. |
