Phlomis tuberosa | Sage-leaf mullein

Phlomis tuberosa, commonly known as sage-leaf mullein or tuberous Jerusalem sage, is a captivating perennial that brings structured elegance and a splash of color to any garden border or group planting. Its statuesque presence, coupled with whorls of pink flowers, makes it an interesting focal point during its bloom time in June and July.

This species is appreciated for its upright growth habit and striking purple stems that are topped with pink to purple blossoms in the warmer months.

Key Features

The Phlomis genus is known for its architectural form and resilience in a garden setting, and Phlomis tuberosa is no exception. The following are some of the key features of this plant:

It boasts an upright growth habit, reaching an ultimate height of 1.5 meters.
The foliage remains a vivid green from spring through autumn.
In the summer, purple stems provide a striking contrast to the pink flowers.
It is drought-resistant, making it a low-maintenance choice for gardeners.
It thrives in a sunny location and is adaptable to all soil types, provided they are well-drained.

Tips

To propagate Phlomis tuberosa, division is the most effective method. It is best to divide the plants in the spring or autumn.
While it is a low-maintenance plant, you may remove unsightly shoots as needed to maintain its neat appearance.
This species does not have a high demand for water. However, ensure that you provide it with average watering, especially during dry spells, to keep it thriving.
No need to worry about extensive pruning; simply deadhead spent flowers to encourage new growth and maintain the plant's attractive form.

Ideal placement of a Phlomis tuberosa

To achieve the best growth and vibrant pink and purple blooms, Phlomis tuberosa should be situated in a location where it will receive full sun exposure. The species is adaptable to a variety of well-drained soils, ensuring versatility in garden placement. Its drought-resistant nature allows it to thrive in areas that may experience dry spells, making it a robust addition to any border or group planting. The upright growth habit of this plant will be highlighted when positioned where it can bask in unfiltered sunlight, ensuring a striking display from June to July.

How do I plant a Phlomis tuberosa?

To ensure successful establishment of Phlomis tuberosa, choose a location that receives full sunlight and has well-drained soil, accommodating its preference for drier conditions. The ideal planting period is during spring or autumn, avoiding extreme cold or heat. Begin by digging a hole that is spacious enough for the pot's contents and loosen the soil at the bottom. Carefully remove the plant from the pot and place it in the hole, ensuring that the top of the root ball is level with the surrounding ground. Backfill with soil, gently firming it down, and water thoroughly to settle the roots. Regular watering should be maintained until the plant is fully established, after which it will be more drought-tolerant.

Pruning a Phlomis tuberosa

Phlomis tuberosa's maintenance is minimal when it comes to pruning. This species thrives with an upright growth habit and requires little intervention. Pruning is generally limited to the removal of unsightly shoots and to encourage a tidy growth form. After the blooming period in summer, it's advisable to cut back spent flower stems to keep the plant looking its best. This not only maintains the plant's shape but also promotes healthy growth for the following season.

Watering a Phlomis tuberosa

Phlomis tuberosa thrives when the soil remains evenly moist, particularly throughout the blooming period of June and July. While it possesses a degree of drought resistance, to support its upright growth habit and maximize its flowering potential, ensure consistent watering during prolonged dry spells. Overwatering should be avoided, as well-drained soil is crucial for the health of the plant. During peak summer temperatures, water deeply to encourage deep root development, which in turn will enhance the plant's resilience against periods of low rainfall.

Fertilising a Phlomis tuberosa

To sustain the robustness and vibrant hues of Phlomis tuberosa, a balanced approach to fertilization is crucial. Adaptable to a variety of soil types, this species flourishes with periodic nourishment. Enriching the soil with a general-purpose fertilizer early in the growing season will set the stage for the forthcoming blooms. Apply the fertilizer just as new growth appears, ensuring an even distribution around the base to avoid direct contact with the stems. A second application may be beneficial as the plant enters its flowering phase in June, aiding in the development of the striking pink and purple blossoms. With its upright growth habit reaching up to 1.5 meters, Phlomis tuberosa's nutrient uptake is essential for maintaining its stately presence in borders and group plantings.

The characteristics of a Phlomis tuberosa

The Phlomis tuberosa offers a delightful surprise with its tubular, hooded flowers that bloom in whorls up the stem, presenting an architectural spectacle. This species thrives in a variety of soil conditions, as long as they are well-drained, making it a versatile choice for gardeners. Its distinct foliage provides textural contrast in borders and flower arrangements. Furthermore, the plant's robust nature ensures it remains a perennial favorite, returning with vigor each year from its pot-grown roots.

Separating/dividing a Phlomis tuberosa

To propagate Phlomis tuberosa, division is commonly employed. This rejuvenates the plant and promotes vigorous growth. Ideally, division should take place in the more temperate periods of spring or autumn. Carefully lift the plant from the soil, ensuring to keep the root system intact. Once excavated, it can be divided by separating into smaller clumps, making sure each division has a portion of the roots. Replant these divisions promptly into well-draining soil, spacing them adequately to accommodate their upright growth habit and eventual height of up to 1.5 meters. Regular division helps maintain the plant's robust nature and abundant summer bloom.
