Product code : JAREC-0151
Organic Olympic Mullein is a majestic plant that brings spectacular verticality and an almost sculptural presence to the garden. With its large rosette of thick, felted, light-grey leaves, Verbascum olympicum establishes a soft, silvery silhouette from the first season, wonderfully catching the light. In a natural, dry, or meadow-style garden, it plays a strong decorative role while actively supporting biodiversity. Its drought tolerance and good hardiness make it a reliable ally for sunny locations where other plants sometimes struggle to establish themselves. Easy to grow in well-drained soil, it requires little maintenance once established and integrates elegantly into wild beds and country scenes.

Olympic Mullein (Verbascum olympicum). Organic Olympic Mullein is a majestic plant that brings spectacular verticality and an almost sculptural presence to the garden. With its large rosette of light grey, thick, felted leaves, Verbascum olympicum establishes a soft, silvery silhouette from the very first season that wonderfully catches the light. In a natural, dry, or prairie-style garden, it plays a strong decorative role while actively supporting biodiversity. Its drought tolerance and good hardiness make it a reliable ally for sunny locations where other plants sometimes struggle to establish.
Recommended sowing period: April to June. Sow seeds on the surface. Germination usually takes 14 to 21 days. For germination, maintain the potting soil at 18 to 22 °C (64 to 72 °F). Transplant young flowers when their true leaves have developed and their roots hold the root ball. Gently handle seedlings and avoid compressing the stem. Under lights, gradually space containers so that the foliage does not overlap. Acclimatization then prepares the plants for sun, wind, and temperature variations.
Olympic mulleins raise their flower stalks above a rosette of leaves. Avoid planting plants too close around the heart, which should remain clear and well-ventilated. Design the composition taking into account the adult habit and the distance from which the flowers will be observed. Small corollas benefit from being placed near a path, while a tall silhouette can serve as a landmark at the back of a bed. Repeat a few plants of the same variety to make the color legible. Keep access for cuts and avoid crowding clumps just to immediately fill the space.

Growing method
Recommended sowing period: April to June. Sow seeds on the surface. Germination usually takes 14 to 21 days. For germination, maintain the potting mix at 18 to 22 °C (64 to 72 °F). Transplant young flowers when their true leaves have developed and their roots hold the soil ball together. Handle seedlings gently and avoid compressing the stem. Under grow lights, gradually space out containers so that the foliage does not overlap. Acclimatization then prepares the plants for sun, wind, and temperature variations. Planting out should be done when conditions match their hardiness. Observe the succession of buds, open flowers, and faded parts to choose appropriate interventions. Pruning should preserve the shoots that will flower next. For tall-stemmed plants, check supports after a windy period. Light pruning helps maintain the silhouette without denuding it. Adapt end-of-season care to the plant's cycle: annuals and perennials do not require the same winter preparation. Choose between extending flowering and preserving seeds on a few stems.
Soil and care
The right care,at the right time.
Care level
Regular during establishment, then adapted to growing conditions
Watering
Weak
Soil type
Prepare well-drained, moderately fertile soil. Transplant young flowers when their true leaves have developed and their roots hold the root ball together. Handle seedlings delicately and avoid compressing the stem. Under lighting, gradually space out the containers so that the foliage does not overlap. Acclimatization then prepares the plants for sun, wind, and temperature variations.
Fertilization
Fertilizing supports growth and takes into account the nutrients already present in the soil or potting mix. Use mature compost or a fertilizer suited to the crop, following the dosage instructions. Avoid using multiple products, especially in a container where roots occupy a limited volume. Water as needed after application and observe the foliage development before re-fertilizing.
Moisture
Moist compost during germination, without standing water; then adjust to the crop
Seasonal care
Olympus mulleins raise their flower stalks above a rosette of leaves. Avoid planting too densely around the crown, which should remain clear and well-ventilated. Transplant young flowers when their true leaves have developed and their roots hold the soil ball. Gently handle seedlings and avoid compressing the stem. Under the lighting, gradually space out the containers so that the foliage does not overlap. Acclimatization then prepares the plants for sun, wind, and temperature variations. Planting is done when conditions match their hardiness. Observe the succession of buds, open flowers, and faded parts to choose useful interventions. A cut should preserve the shoots that will flower next. For tall-stemmed plants, check the supports after a windy period. A light cleaning helps maintain the silhouette without denuding it. Adapt the end of the season to the plant's cycle: annuals and perennials do not require the same preparation for winter. Choose between extending flowering and preserving seeds on a few stems. Removing faded flowers is suitable for many annuals, while capsules and dry inflorescences can have decorative interest. Keep plants identified when they no longer bear flowers and remove spontaneous seedlings that occupy a pathway. Organic Olympus mullein is a majestic plant that gives the garden spectacular verticality and an almost sculptural presence.
Container growing
A garden,within reach.
Recommended pot size
A stable container with drainage holes, wide enough for the plant to spread out, and deep enough for the roots
Choose this exposure: full sun. Reserve this spacing around the plant: 50 to 70 cm (20 to 28 in). A floral container arrangement must allow space for each plant to grow. Place upright forms where they remain visible and allow trailing stems to occupy the edge when present. Check that the combined plants share the desired exposure and moisture. After a few weeks, observe the areas that are becoming denser and remove only damaged parts or stems that disrupt the balance of the composition.

Companion plants
In a diversified planting, you can dedicate neighboring sections to these plants: yarrow, echinacea, sage. This arrangement helps organize space and harvests. Respect each plant's height, light, and water needs, without crowding the foliage. Maintain a pathway for watering and picking, then remove spent crops to free up space. This organization simplifies maintenance but doesn't guarantee pest protection. Design the composition considering the mature plant habit and the distance from which the flowers will be observed.

Organic Olympian Mullein is a majestic plant that gives the garden spectacular verticality and an almost sculptural presence.
How to care for Olympic Mullein during the season?
Choose between extending the flowering period and retaining seeds on a few stems. Deadheading is suitable for many annuals, while seed pods and dry inflorescences can have decorative appeal. Keep plants identified when they are no longer flowering and remove spontaneous seedlings that are blocking a pathway. Observe the succession of buds, open flowers, and faded parts to choose useful interventions. Pruning should preserve shoots that will flower next. For tall-stemmed plants, check supports after a windy period. A light tidy-up helps maintain the plant's shape without stripping it bare.
