Phlomis ‘Russeliana’

Phlomis russeliana, commonly known as "Turkish sage", is a bold, long-lived perennial prized for its structural beauty, drought tolerance, and pollinator-friendly flowers. With large, softly hairy leaves and tall, tiered spires of soft yellow flowers through summer, it provides both texture and colour in borders, gravel gardens, and wildlife-friendly spaces. This easy-care plant is ideal for gardeners seeking dependable performance with a naturalistic look.

 

Key Features

  • Evergreen foliage: Large, softly hairy, heart-shaped leaves provide year-round presence

  • Striking seed heads remain well into winter for structural and wildlife interest

  • Drought tolerant: Once established, requires little watering

  • Low-maintenance: Only requires cutting back in late winter or early spring

  • Height: 90cm (3ft)

  • Spread: 75cm (2.5ft)

  • Flowering: Tall whorls of pale yellow flowers from June to August

  • Simple to prune: Best left unpruned except for removal of unsightly shoots and deadheading, unless some shaping is required. Do this by lightly cutting back shoots after flowering. Deadheading and removal of dead, damaged and diseased growth can be done at the same time.

  • Hardy: Hardy in the UK down to temperatures of -15 degrees Celcius (RHS hardiness rating H6)

 

Growth & Habit

Phlomis ‘Russeliana’ forms a strong clump of broad, grey-green leaves which are semi-evergreen in milder regions. From early to mid-summer, tall flower spikes rise above the foliage, each bearing several layers (whorls) of soft yellow, hooded flowers. After flowering, the seed heads dry into attractive architectural shapes, adding visual interest through autumn and winter.

 

Planting Advice

  • Position: Best in full sun but tolerates light shade.

  • Pottedgrown in pots can be planted at any time of the year providing the ground is not frozen or waterlogged

  • Soil: Prefers well-drained soil and performs well even in poor or dry conditions. Avoid heavy, waterlogged soils.

  • Planting Depth: Plant with the crown level with the soil surface. Water well after planting.

  • Spacing: Leave 60–90 cm between plants to allow room for clump expansion.

Plant in spring or early autumn to allow roots time to establish before hot or cold weather.

 

Care & Maintenance

Phlomis ‘Russeliana’ is extremely easy to grow and requires little care once established. It’s particularly useful in low-maintenance and drought-tolerant schemes, thriving in hot, dry summers with little additional watering.

Apply a mulch of compost or well-rotted manure in spring to feed the soil, although this isn’t essential for its performance.

 

Uses in the Garden

  • Ideal for dry borders, Mediterranean-style planting, and gravel gardens

  • Adds strong structure and contrast to mixed perennial beds

  • Pairs well with ornamental grasses, Salvia, Nepeta, and Achillea

  • Excellent for wildlife gardens due to its long flowering period and seed head value

  • Works well in naturalistic or prairie-style plantings

 

If you're looking for a tough, beautiful, and wildlife-friendly perennial with strong visual presence, Phlomis ‘Russeliana’ is a standout choice. From its bold foliage to its tiered summer flowers and decorative seed heads, it offers year-round appeal with very little effort – perfect for both new and experienced gardeners alike.

Buying Shrubs from Jacksons Nurseries

At Jacksons Nurseries we sell a variety of shrubs both evergreen and deciduous with a variety of flowering times throughout the year. At certain times of the year our shrubs you buy from us may not look like the images shown on our website when deciduous leaves have fallen, the shrub has finished flowering or has been trimmed back.

Some leaves on evergreen shrubs can be damaged in winter by frost or harsh winds but in spring new leaves will readily replace those damaged. This is quite normal on many evergreen varieties and is preferable to plants grown with excessive protection that show cold shock once planted out and establish less satisfactory initially.

Availability: Stock availability figures are provided as a guide only. There is a delay between orders being placed and the plants being gathered by our pulling team. During this time it may be possible for a member of the public to purchase these plants from our Garden Centre, while this is rare it is a possibility and we will notify you of any problems as soon as possible. This figure may also include plants that have not yet be flagged as unsaleable.

Pre-order: Pre-order times are given as a guide only and may vary dependent on the growing season. Orders containing Pre-ordered products will be shipped as a single order when all items become available. Large orders may be part shipped, please contact us on 01782 502741 or email sales@jacksonsnurseries.co.uk.

* Please Note: Shrubs in 20 litre pots and above might require a pallet delivery starting at £79.99 per pallet. Depending on the exact pot size and height it may be possible to get approximately 5 plants per pallet at no extra cost. The maximum height we can dispatch on a pallet is 2.0m, this includes the height of the pallet and pot.

Shrubs are deciduous or evergreen woody plants, and often provide fragrant flowers, berries and foliage. They are good for structural framework, and they can provide a wonderful shelter and food source for wildlife.

Planting and Conditions

Container grown shrubs can be grown at any time of year. It is a little known fact that shrubs planted in the autumn and winter will be easier to look after than those planted in the spring and summer, because they will have time to establish and become hardy in the cooler months.

Plant the shrub at the same depth as it was in its original pot. Planting too deeply can result in root and stem rot.

One of the biggest causes of death in new shrubs is drought stress, so keep it well watered until it’s established.

Make sure you loosen the soil prior to planting. Most shrubs are tolerant of most soil types as long as it is fairly well draining.

Most shrubs will grow happily in containers, but they will be much more demanding on feeding and watering than shrubs in the ground would be. They will also need potting on every couple of years so that they don’t suffocate or become stunted in their pot.

Aftercare and Pruning

Once established, shrubs generally do not require much water. However, at first they need careful, frequent watering and should not be left to dry out.

Shrubs in the ground are generally not demanding and in most cases, annual feeding with general purpose fertilizer will suffice. Shrubs in containers may need more feeding; usually from early spring until late summer.

Shrubs also benefit from mulching in order to supress weeds, conserve moisture and provide vital nutrients. Mulch also greatly improves soil conditions. Shrubs can be mulched in late winter, after fertiliser has been applied, but it can be mulched through autumn to late spring as long as the ground is damp.

All shrubs benefit from dead-heading once spent flowers become apparent. Rhododendrons and Lilac especially benefit from the removal of dead flowers.

Some shrubs may show signs of reverted growth or ‘sporting’. This is where random shoots of different leaves associated with the plant’s parentage begin to appear. Most commonly this is where plants with variegated leaves sprout pure green growths instead of variegated ones.

To control reversion, remove reverted shoots promptly to discourage them. Reverted shoots are usually much more vigorous than the variegated ones, and thus should be completely pruned out and cut back into wood containing variegated foliage.

Potential Issues

Although shrubs are usually very robust garden plants, they can sometimes start to decline with no apparent or obvious reason.

This will start with browning leaves, which could indicate plant stress due to lack of water or waterlogging, an establishment failure or, in the worst case scenario, honey fungus. Another cause of leaf browning is a high salt content in the soil. This could be a natural occurrence, especially if you live near the ocean, or it could be from over fertilisation.

To remedy a high salt content, cut back on fertiliser and step up your watering regime for the next few weeks. If you live by the ocean, this will be harder to remedy—but stepping up your watering will help to wash some of the salt away all the same.
