Colorful, fragrant and very easy to grow: presoak the seeds for 24 hours for better results and sow by September-October in well drained soil or in dry problem areas. Plant 2 seeds per pot, cover them with ¼ inch fine soil, seed needs darkness to germinate. Once the seedlings are established, they will continue to spread and bloom. Ideal spacing in the garden is 8 to 10 inches. Do not use excess fertilizer as plants will produce excessive foliage at the expense of flowers.
