I have only a small garden, but managed to grow red wild clover. You got to wait for the flowerheads to be dry, when you pick em they must fall into your hand just like that. No pulling. Keep em in an envelope in the winter and sow in march. You can throw em down straight away where you want em as well, they do grow, but i've had more luck in spring. I transplanted them to a place where they block wind in a row. They don't like it, but with a little water if they looking sorry they'll survive. They don't like the bits of the garden i didn't make loose with the spade.
Good luck to you.
