Senecio Cineraria Silver Dust

Senecio cineraria Silver Dust
Dusty Miller, Silver Ragwort
Despite a quality control of my order, I was given agapanthus seeds instead of cineraria seeds, which is why I had ordered on the website.

Description
Silver Ragwort Silver Dust is a persistent shrub-like plant, cultivated as an annual for its decorative, cut, and silvery foliage.
Silver Ragwort belongs to the Asteraceae family and is known by many synonyms: Senecio maritimus, Senecio candicans, Cineraria maritima and Senecio bicolor ssp. cineraria.
Native to the Mediterranean basin, Senecio cineraria likes warm and sunny exposures as well as mild winters. It does not withstand temperatures below 5 °C (41 °F) but tolerates maritime climates and sea spray well.
Senecio cineraria Silver Dust is a small bushy shrub that grows to a height of 25 to 30 cm (9.8 to 11.8 in) with a similar width. Its leaves, 10 to 15 cm (3.9 to 5.9 in) long, are lanceolate or ovate and deeply cut, resembling oak leaves. The epidermis is velvety and particularly silvery white, hence the choice of this name: Silver Dust.
Although it has little appeal in terms of its foliage, it is worth noting the appearance of yellow flowers in July-August. These are 2 to 3 cm (0.8 to 1.2 in) heads carried in trailing corymbs.
Silver Ragwort Silver Dust is used for the significant contrast it can create among beds of perennial or annual plants with vibrant colours. It has long been used in mosaic gardening. Planted along borders, it highlights beds and clearly defines short grass meadows. Finally, in pots and containers, it pairs well with the colourful foliage of purple Coleus and miniature Dahlias.

Planting and care
Sow Silver Ragwort Silver Dust from February to March in a tray. Use good-quality compost that you will sift over the surface to bind the seed to its substrate. Before sowing, lightly press the compost down using a board. Sow your seeds by broadcasting. Cover the seeds by sprinkling compost or vermiculite on top, lightly press, and water generously with a fine rain. Place your tray in light, avoiding direct sunlight, at a temperature of 18 °C (64.4 °F) to 24 °C (75.2 °F).
The seeds will germinate in 10 to 21 days. As soon as the plants are manageable, transplant them into 7 cm (2.8 in) buckets. Keep the compost moist but not excessively during growth. Then, 15 days before their final placement, start gradually acclimatising them to a temperature of 15 °C (59 °F).
By the end of May or the beginning of June, the temperature will be warm enough in the garden to plant your young plants. Choose a sunny location, add a good scoop of compost to each planting hole, and space your plants 30 cm (11.8 in) apart.
If you wish to keep your Sea Ragworts for the following year, remember to protect them from severe frost or bring them indoors into a frost-free greenhouse or conservatory.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
