Rudbeckia ( Black-Eyed Susan ) Seeds

Rudbeckias have become one of our most popular garden plants in recent years. And it's not surprising as the bushy plants produce masses of colourful flowers with a long flowering period from July to October.
They are characterised by their colourful daisy-like flowers surrounding a prominent conical disk.
Rudbeckias can be annuals, biennials or herbaceous perennials, the annuals grown as half-hardy annuals, sown indoors in warmth. The annual varieties may survive from year to year if left in the garden, but flowering may be reduced in subsequent years.
Although yellow is the prominent colour, in recent years numerous red- and orange-flowered varieties have been produced.
Useful gardening information
Hardiness will vary with species and not all Rudbeckia are perennial plants. Those that are generally are reliable in USDA Hardiness Zones 4 - 9.

You will get the best flowering from your plants in full sun, but the plants can handle partial shade.
Rudbeckia plants start blooming in mid-summer and can repeat bloom into fall. Seed started perennials can bloom the first year if started early enough.
They are not particular about soil but do best in soil that is not too rich, with well-draining conditions.
Start seed about 6-8 weeks before last expected frost. Perennial varieties will germinate best if the pots are kept in the refrigerator or similarly cold place for 4 weeks after seeding. Then move them back to a warm spot about 70°F to 72°F until seeds actually germinate.
Rudbeckia are easy to establish, naturalize well, and require little maintenance other than deadheading.
Keep plants well watered the first season, to get them established. Once established, the will be quite drought resistant.
