I seem to have not had a green thumb for this sowing that I did inside my greenhouse. The sowing did not sprout.

Description

The Rudbeckias hirta 'All Sort' Mixed are perennial ephemeral plants that mix single, semi-double, or double flowers in warm colours. They range in height from 60 to 100 cm (24 to 39in).

The Rudbeckias 'All Sort' Mixed are called ephemeral because they will not last more than 2 to 3 years in the garden, but they easily self-seed. They are, therefore, cultivated as annual or biennial plants.
The flowers of Rudbeckias 'All Sort' Mixed are large solitary single, semi-double, or double daisies (heads) with golden yellow, orange, bronze, or mahogany petals. The centre of the single flowers is prominent and generally dark brown to almost black. The diameter of the flowers varies from 7 to 13 cm (3 to 5in). The many flowers blooming from July to October form an impressive mass. The long and sturdy stems of the Rudbeckias 'All Sort' Mixed make them suitable for planting in borders and provide a source of fresh flowers for creating beautiful summer bouquets.
At the end of the summer season, the petals fade and fall, and the centre of the single flowers dries and becomes woody. These flowers can then be picked and incorporated into a dried bouquet.

The foliage consists of a cluster of lanceolate basal leaves, toothed, dark green, measuring 5 to 10 cm (2 to 4in), from which sturdy and branched flowering stems rise. The stems bear narrower, somewhat ovate cauline leaves.

Hardy, the Rudbeckia hirta 'All Sort' Mixed thrives in sunny or semi-shaded locations. They prefer a rich, heavy, and moist soil that is well-drained. These plants are particularly resistant to rainy weather.

An ecological asset: Throughout summer, the nectar-rich flowers of Rudbeckias attract pollinating insects and butterflies to your garden. This is a great way to improve your garden's ecosystem and promote fruit and vegetable production in your vegetable patch. In autumn, you can admire the constant ballet of birds that come to feed on the mature seeds they find in the dried flower heads.

Planting and care

Before sowing the Rudbeckia, place your seeds in the vegetable compartment of your refrigerator for 4 weeks. This will break the seed's dormancy and improve your sowing's success.

Sow the Rudbeckia All Sort Mixed from February to April in a seed tray. Use a good quality compost that you will sieve on the surface to bind the seed to its substrate. Before sowing, gently press down the compost with a board. Sow your seeds by broadcasting. Cover the seeds by sprinkling compost on top or using vermiculite, gently press down and water generously with a fine rain. Place your seed tray in a well-lit area, without direct sunlight, at a temperature of 20°C (68°F) to 25°C (77°F). Lower the temperature at night to 18°C (64.4°F) to create a beneficial alternation for germination.

The seeds will germinate in 10 to 21 days. When the seedlings are manageable, transplant them into 7cm (3in) pots. Keep the compost moist but not excessively during growth. Then, 15 days before their final planting, start gradually acclimating them to a temperature of 15°C (59°F).

By the end of May or early June, the temperature in the garden will be warm enough to plant your young plants. Choose a sunny location. Add a good shovel of compost to each planting hole. Space your plants 30 cm (12in) apart.

Regularly remove faded flowers to maintain their beauty and promote repeat flowering.
