Description
Rudbeckia hirta is native to the United States and is a synonym for Rudbeckia gloriosa.
Rudbeckia Rustic Dwarf Mixed is an ephemeral perennial plant that is often cultivated as an annual or biennial and is known for its ease of cultivation. Planted in the garden, it will not last for more than 2 to 3 years, but it self-seeds spontaneously quite easily. Rudbeckia gloriosa Rustic Dwarf Mixed is characterized by its medium height of 60 cm, making it much shorter than the type species (which reaches a height of 100 cm), and most especially by the original colouring of its huge, daisy-like blooms.
The flowers of Rudbeckies Rustic Dwarf Mixed are large solitary daisies (pseudanthia) with prominent green centres and yellow and brown corollas. The long petals are regularly arranged around the centre of the flower, giving it a diameter that varies between 10 and 12 cm. The large number of flowers which renew themselves continuously from July to October, form a blooming mass that ripples with each passing breeze. This flowerbed is a source of fresh flowers for the making of bouquets.
At the end of summer, the yellow petals fade and fall, while the cone-shaped centre of the flowers dries and mummifies. Flower can also be picked at this stage and incorporated into a dried flower bouquet.
The foliage consists of a clump of 5 to 10 cm long, lanceolate, toothed, dark green basal leaves from which rise sturdy, branched flower stems. The stems bear cauline leaves that are more narrow and oval-shaped.
The Rudbeckia hirta Rustic Dwarf Mixed likes sunny or partially shaded situations. It thrives in rich, heavy, moist soil as long it is well-drained. Its rhizomatous roots allow its clumps to grow and fill out quickly.
Ecological benefits : All summer long, the melliferous flowers of the Rudbeckias attract pollinating insects and butterflies to your garden. This is a good way to improve the ecosystem of your garden and to promote the production of fruit and vegetables in your vegetable garden. In autumn, you will be able to admire the incessant ballet of birds that come to feed on the mature seeds they find in the heart of the dried flowers.

Planting and care
Before sowing Rudbeckia, place your seeds in the vegetable drawer of your refrigerator for 4 weeks. This will lift the dormancy of the seed and thus improve the success of your sowing.
Sow Rudbeckia Rustic Dwarf Mixed from February to March in a tray. Use good quality soil and sieve the surface so that the seed will bind to the growing medium. Before sowing, lightly tamp down the soil with a small plank of wood. Broadcast your seeds. Cover the seeds by sprinkling topsoil or vermiculite on top, tamp down lightly and water generously with a fine spray. Place your tray in the light, without direct sunlight, at a temperature of 20°c to 25°c. Lower the temperature at night to 18°c in order to create a beneficial alternation for better results.
Seed emergence will take 10 to 21 days. As soon as the seedlings can be handled, transplant them into 7 cm pots. Keep the soil moist but not waterlogged during growth. Then, 15 days before finally placing them in their final positions, begin to acclimatize them gradually to a temperature of 15°c.
At the end of May, beginning of June, the temperature in the garden will be warm enough to planting out your young plants. Choose a site with plenty of sunshine. Add a good shovelful of compost to each planting hole. Space your plants 30 cm apart.
Regularly remove faded flowers to maintain the plant’s beauty and encourage the renewal of blooms.

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).

In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The harvesting period indicated on our website applies to countries and regions in USDA zone 8 (France, England, Ireland, the Netherlands).
In colder areas (Scandinavia, Poland, Austria...) fruit and vegetable harvests are likely to be delayed by 3-4 weeks.
In warmer areas (Italy, Spain, Greece, etc.), harvesting will probably take place earlier, depending on weather conditions.
The sowing periods indicated on our website apply to countries and regions within USDA Zone 8 (France, UK, Ireland, Netherlands).
In colder areas (Scandinavia, Poland, Austria...), delay any outdoor sowing by 3-4 weeks, or sow under glass.
In warmer climes (Italy, Spain, Greece, etc.), bring outdoor sowing forward by a few weeks.
The planting period indicated on our website applies to regions in USDA Zone 9a (East Coast and Midlands: Dublin, Wexford, Waterford, Kilkenny, Portlaoise). It will vary depending on where you live:
- On the west coast and in the north-west (Galway, Limerick, Sligo, Donegal, Westport), delay planting by 1 to 2 weeks in spring and bring it forward by 1 to 2 weeks in autumn compared to the dates given, preferably choosing periods without strong winds.
- In the inland hills and plateaus (Wicklow Mountains, Macgillycuddy’s Reeks, Connemara, Killarney), it is best to plant in spring (April–May) or autumn (September–October), avoiding periods of waterlogged soil in winter and strong winds, which pose the main risk to newly planted trees in these areas.
The flowering period indicated on our website applies to regions in USDA Zone 9a, such as the East Coast and Midlands, including Dublin, Wexford, Waterford, Kilkenny and Portlaoise.
This will vary depending on where you live:
- On the west coast and in the northwest (Galway, Limerick, Sligo, Donegal and Westport), it will be delayed by one to two weeks compared to the given dates, due to stronger Atlantic winds and less spring sunshine.
- In the inland hills and plateaus (the Wicklow Mountains, the Macgillycuddy's Reeks, Connemara and Killarney), flowering will be delayed by two to three weeks. Flowering mainly occurs between May and July, with the limiting factors being less frost and more of the excessive humidity, strong winds and lack of sunshine that are characteristic of these areas.
