Wallflower seeds are the most popular spring bedding item. They produce beautiful flowers which are very fragrant and a great addition to any garden (most commonly used in borders).
Best grown as a hardy biennial, the seeds need to be sown outdoors between May and July so that the plant flowers between April and June the following year.
Wallflower seeds should germinate within 7 to 14 days. As the seedlings grow thin in stages to achieve final spacing of 15cm so the plants can grow nice and bushy. In the early autumn pinch out the main growing point and transplant the plant to their flowering positions, 30cm apart.
