Shades of meaning
Fernald has no entry of its own for floriculture; he lists it under agriculture.
Where he writes about it:
Gardening in general, kitchen-gardening, the cultivation of vegetables, etc., for the household, market-gardening, the raising of the same for sale, floriculture, the culture of flowers, and horticulture, the culture of fruits, flowers, or vegetables, are all departments of agriculture, but not strictly nor ordinarily of farming; farming is itself one department of agriculture. — from agriculture
