Olympic Mullein Verbascum olympicum
ABOUT
Verbascum olympicum, commonly known as Olympic mullein, is a striking perennial plant that makes a bold impression in any garden setting. The foliage of the Olympic mullein forms a basal rosette characterized by large, woolly, gray-green leaves that are oblong to lance-shaped, with a slightly ruffled and felt-like texture. Rising above the foliage, the Olympic mullein produces a remarkable floral spike that carries abundant saucer-shaped flowers. These blooms are usually bright yellow, creating a vibrant contrast against the soft gray-green of the leaves. Each flower is comprised of five rounded petals that surround a prominent central stamen, giving the blossom a distinctive and eye-catching appearance. The profusion of sunny flowers not only adds a splash of color but also attracts various pollinators like bees and butterflies, which find the plant irresistible. The overall appearance of Olympic mullein, with its combination of textural foliage and attention-grabbing flowers, makes it a favorite choice for gardeners looking to add a touch of drama to their landscapes.

WaterFor Olympic Mullein, it's essential to allow the soil to dry out between waterings, as this plant prefers a drier soil condition. Generally, watering once a week during the growing season should be sufficient, adjusting for rainfall, and more sparingly in the winter. When you do water, aim for about 1 gallon per plant to ensure deep watering that encourages root growth, depending on the size and maturity of the plant. Overwatering can lead to root rot, so it's important not to let the plant sit in soggy soil.
LightOlympic Mullein thrives in full sun conditions, meaning it should receive at least 6 to 8 hours of direct sunlight per day. The plant is best situated in a spot where it can bask in the sun's rays unhindered, as ample sunlight is crucial for the growth and blooming of this species. Partially shaded areas can lead to less vigorous growth and fewer blooms.
TemperatureOlympic Mullein performs well in a wide range of temperatures but prefers warmer conditions. It can withstand minimum temperatures down to about 20°F, but it grows optimally when temperatures are between 60°F and 80°F. Ensure that the plant is not subjected to prolonged periods of frost to avoid damage.
PruningFor Olympic Mullein, pruning is done to remove spent flowers and encourage a second bloom. Deadheading, or cutting off the faded flower spikes, can also prevent the plant from self-seeding excessively. The best time for pruning is right after the first flowering, usually in mid-summer. Additionally, removing damaged or diseased foliage as needed helps maintain plant health.
CleaningAs needed
SoilThe Olympic Mullein requires well-draining soil with a sandy or rocky texture, enhanced with organic matter for nutrient retention. The best soil mix comprises equal parts of sand, loam, and compost. Aim for a slightly alkaline soil pH, between 6.8 and 7.5.
RepottingOlympic Mullein rarely needs repotting as it is often grown as a biennial; if grown as a perennial, consider repotting every two to three years, or if it outgrows its container.
Humidity & MistingOlympic Mullein tolerates a wide range of humidity levels but prefers drier conditions. It thrives best in low to moderate humidity environments, making it suitable for average home or garden settings.
Suitable locationsIndoor
Ensure full sun, well-draining soil, minimal water, and sparse fertilization.
Outdoor
Plant in full sun, well-drained soil, space 45cm apart; low maintenance.

Life cycleVerbascum olympicum, commonly known as Greek Mullein, begins its life cycle as a seed that germinates typically in early spring when the soil temperature and moisture levels are suitable. Following germination, the seedling establishes a rosette of basal leaves, entering a vegetative growth stage that can last for one or more seasons. During this time, Greek Mullein invests energy in developing a strong root system and accumulating nutrients. The plant then progresses to the reproductive stage, typically in its second year, where it sends up a tall flowering stalk that can reach up to 2 meters in height with dense clusters of yellow flowers that are pollinated by insects. After pollination, the plant produces capsules containing numerous seeds, which are dispersed by wind or contact with animals. Eventually, the plant completes its life cycle by senescing and dying, leaving the seeds to initiate the next generation.
PropogationPropogation time
Spring to Summer
Verbascum olympicum, commonly known as Olympic mullein, is a perennial plant typically propagated by seeds. The ideal time for sowing these seeds is in late winter to early spring. The most popular method of propagation is by seed, which is both easy and efficient. To propagate Olympic mullein by seed, simply scatter the seeds over a well-draining soil mix and lightly press them into the surface, as they need light to germinate. Keep the soil moist but not waterlogged, and position the seed tray in a bright, warm location. Germination usually occurs within two to three weeks. Once the seedlings are large enough to handle, they can be transplanted into individual pots before eventually being moved outdoors after the risk of frost has passed.
