How to grow rudbeckia from seed
Sow your rudbeckia seed in late winter to late spring. Rudbeckia hirta is a short-lived perennial or biennial but often grown as a half-hardy annual. The seeds are germinating the easiest in a more warm environment, for example indoors or in a greenhouse on a heat mat if the weather is still cold.
Seeds can also be sown directly where they are to flower, two weeks before the last expected frost, but to give them a head start, sow indoors from mid-February to June, about six to eight weeks you can plant the seedlings out in the garden. The seeds need light to germinate, don’t cover the seeds with soil.
