ABOUT

Verbascum densiflorum, commonly known as the denseflower mullein or dense-flowered mullein, is a plant that is well recognized for its striking appearance. The plant typically features a tall, upright stem that supports a dense spike of yellow flowers. These flowers are characterized by their open, saucer-shaped design, with five rounded petals surrounding a central stamen cluster with striking orange anthers. The foliage of denseflower mullein is equally notable, with leaves that are large and often described as velvety or felt-like to the touch. The leaves are arranged in a rosette at the base of the plant, and they are known for their soft, hairy texture, which gives the plant a silvery-green appearance. As the leaves ascend the stem, they become smaller and are spaced increasingly closer to one another. The overall impression of denseflower mullein is of a plant that is both bold and conspicuous, particularly when in bloom. The yellow flowers create a vivid display against the grey-green of the leaves and can attract a range of pollinators to the plant. Despite its striking size and form, the plant's actual dimensions are not a focal point in this description.

Pruning
  • water dropWater

    Mullein (Verbascum densiflorum) prefers consistent moisture, especially when establishing growth. It's best to deep water the plant to encourage root development. Therefore, water the mullein with approximately 1 gallon weekly for established plants, adjusting for rainfall, as the plant is drought-tolerant once established. In hotter, dryer periods, you may need to water twice a week. Use a slow and gentle watering method, such as a drip system, to avoid eroding the soil around the base.

  • sunLight

    Mullein thrives under full sunlight, which ensures the plant’s healthy growth and flowering. Select a spot where it can receive at least 6 to 8 hours of direct sunlight daily.

  • thermometerTemperature

    Mullein is quite hardy, coping with temperatures as low as 20°F and as high as 90°F, though it grows best when temperatures range between 55°F and 85°F.

  • scissorsPruning

    Mullein should be pruned to remove spent flower spikes and encourage more blooms. It's best to prune during late summer after the flowering period. Pruning can be done as needed throughout the growing season to maintain plant shape and encourage new growth.

  • broomCleaning

    As needed

  • bambooSoil

    Great mullein (Verbascum densiflorum) thrives in well-draining, sandy or loamy soil with a pH between 6.0 and 8.0. A mix of two parts sand, one part loam, and one part compost provides nutrients and proper drainage. Periodic addition of lime can help maintain an alkaline pH.

  • plantRepotting

    Great mullein typically does not need frequent repotting. It is a biennial plant, often completing its life cycle in two years, thus repotting might not be necessary. However, if grown in a container, consider repotting every year during its growing season to refresh the soil.

  • water dropsHumidity & Misting

    Great mullein prefers a dry environment and does not require high humidity levels. It is tolerant of low humidity and is well-suited to dry climates as long as its soil moisture needs are met.

  • circleLife cycle

    The common mullein (Verbascum densiflorum) typically begins its life cycle as a seed, which germinates when environmental conditions of warmth and moisture are met, often in the spring. It initially grows into a rosette of soft, fuzzy leaves close to the ground during its first year, and this is its vegetative phase where it focuses on accumulating energy and nutrients. In its second year, the plant bolts, sending up a tall flower spike that can reach up to 2 meters in height, and this marks its reproductive phase. This spike is covered in yellow flowers that open sequentially, are pollinated by insects, and subsequently produce numerous small seeds. After the flowering and seed production, the common mullein completes its life cycle when it dies, being a biennial plant. The seeds can survive for several years in the soil, ensuring the continuance of the species through a new generation of plants.

      Spring to Summer

    • The common mullein, or Verbascum densiflorum, is typically propagated through seeds. The ideal time to sow mullein seeds outdoors is in late spring to early summer when the soil has warmed up. To propagate the common mullein using seeds, these are scattered directly onto the surface of the soil, as they require light to germinate. A thin covering of soil can be used, but ensure it is not too thick, otherwise, it may inhibit germination. Mullein seeds should be lightly watered and kept moist until germination, which usually occurs within 2-3 weeks in temperatures around 70°F (21°C). Once seedlings are large enough to handle, they can be thinned and transplanted to their final growing location. This method is favored for its simplicity and the ability to produce a large number of plants from a single seed packet.
