Flower seeds to sow in December

Take your pick of some of the best flowers to sow in December.

If your green fingers are itching in midwinter, there are flower seeds you could sow, and you may be rewarded with early blooms.


Shorter daylight hours can make it tricky to provide enough light for your seedlings. To counteract this, sow and grow in a bright spot without too much direct sunlight, which can damage seedlings.

Take a look at this video on sowing seeds indoors for more advice, including a handy tip on how to boost light levels.
