This group includes plants many of which are semi-woody in character and which fundamentally are known as herbaceous stock. There is still a great opportunity to introduce a number of the northern types of herbaceous stock into the garden plantations of Florida. This list is compiled as a partial list of those which to date have been found to be of real interest and value. Many other plants may be added to this list in safety, but because of the lack of record of experiments conducted with their growth in this climate they have not been included.
The climate of middle and southern Florida has been aptly described by one horticulturist as that of a great out-of-door greenhouse. The climate is such that many of the flowering annuals so familiar to the gardens of the north prove failures when grown in the Florida garden. Such plants as the annual larkspur, snapdragon, China aster, sweet William, and baby's breath, producing such an abundance of cut flowers when grown in the north, are grown with little success in Florida.
Nasturtiums, annual phlox, gaillardia, zinnias, and marigolds produce quantities of flowers.
In the north such annuals are seeded in the latter part of April. Flowers are then produced early in July. In the Florida garden, if flowers are desired early in January, the nasturtium seeds are sown during the first week of September, alyssum seeds not later than November tenth, sweet peas in early September, and the other annuals, such as annual phlox, gaillardia, verbenas, annual carnation, and calendulas, are seeded not later than the first week in October. If flowers are wanted at an earlier date seeds should be sown proportionately earlier.
The winter months are better for the growth of flowers. Very few persons in Florida attempt to grow annuals during the hot and usually dry months of summer.
It seems at first, to the garden lover from the north, that any of the northern garden flowers should grow vigorously in the Florida climate. Many keen disappointments await these persons. Those who have tried growing many kinds in an effort to obtain garden flower effects and flowers for table use have finally accepted, as the reliable types, the few that are starred in the following group:
