You may think that December is far too late in the year to plant flower seeds, but that is not the case. There are many flowers you can sow in winter to bring you earlier blooms in spring and summer.
Most flower sowing in December is done indoors, and plants are started in a greenhouse or a heated propagator. Some, though, do need a period of cold and can be planted in a cold frame or directly in the ground, provided it is not frozen.
