Description
From June until the first frost, organic Rudbeckia hirta 'Marmalade' is covered with numerous large semi-double orange-yellow heads surrounding a black centre. This perennial plant is usually grown as an annual. It forms a tall clump, 60 cm in height and about 40 cm wide that will fit well in a flower bed or a container. It is also an excellent cut flower for creating rustic bouquets. Easy to sow and cultivate in all types of soil in full sun or partial shade. Sow from February to April in a seed tray.
From the Asteraceae family, Rudbeckia hirta is a perennial plant native to the meadows of North America. Due to its short lifespan, it is more often grown as an annual or biennial plant. It does not live more than 2 to 3 years but naturally self-seeds quite easily. This Rudbeckia forms a clump of green basal leaves that are 5 to 10 cm long and slightly hairy. From the clump, sturdy and branched floral stems emerge, bearing narrower cauline leaves. These stems bear large "daisies" of about 8 to 10 cm in diameter. The ray florets are orange-yellow, surrounding a prominent cone that is dark brown, almost black, creating an interesting contrast. The 'Marmalade' cultivar is appreciated for its generosity: its bright flowers succeed from June until the first frost, making it possible to create lovely bouquets all summer long. Its flowers are nectar-rich. Plant a few in the vegetable garden to attract pollinating insects and butterflies. Leave the last dried flowers of autumn on the plant, as birds feed on the mature seeds contained in their centres.
Rudbeckia 'Marmalade' will brighten up any flower bed or border. It can also be planted in a large container. Pair it with other cut flowers to have on hand for creating charming bouquets. Consider Achillea millefolium Summerwine with its bright red flowers and Zinnia Pop Art Golden and Red with its yellow flowers speckled with red. Add a grass to your composition to lighten it up, try Stipa tenuissima Pony Tails, which is decorative with its golden summer flowering

Planting and care
Before sowing your organic 'Marmalade' Rudbeckia, place your seeds in the vegetable compartment of your refrigerator for 4 weeks, breaking the seed dormancy and thereby improving the success of your sowing.
Sow the seeds in a seed tray between February and April, on the surface of a compacted seed compost. Cover the seeds with about 5 mm of substrate, lightly firming it down, and water with a fine mist. Place your tray in a well-lit area, without direct sunlight, at a temperature of 18°C to 22°C. The seeds will germinate in 10 to 15 days. As soon as the plants are strong enough to handle, transplant them into 7 cm pots. Gradually acclimatise them to a temperature of 15°C, 15 days before their final planting. Once all risk of frost is gone and the soil is well warmed up, plant your rudbeckias in full sun or partial shade in ideally deep and rich soil. Allow a distance of 20 to 30 cm between each plant.
It is also possible to sow directly in the ground in May or to sow under cover in September-October for planting in the garden the following spring.
Regularly remove faded flowers to prolong the flowering period.

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.
