This list is not everything that can be sown but is a very good starting point. Most of the seeds here can be bought from the same seed supplier that I use for the Higgledy Garden flowers, namely Sarah Raven. Some seeds I use are from Unwins. I shall put links at the bottom of the page if you wish to visit them. Where possible I shall put links to articles I have written. I am writing this in late August so will deal with Autumn planting first and then later in the year carry on with Spring grown hardy annuals and half hardy annuals. (Click on either to learn how to grow them)
I hope this is of some assistance. :)
*September & October.
