Jerusalem Sage Phlomis lanata
ABOUT
Phlomis lanata, commonly known as Jerusalem Sage, is a visually striking plant with a distinct appearance. This evergreen perennial is known for its woolly, silvery-grey foliage that creates a textured, dense mat of leaves. The leaves themselves are thick and leathery, often with a wrinkled, crinkled look that adds to the plant's tactile appeal. Jerusalem Sage produces whorls of tubular, two-lipped flowers, which are usually a vibrant yellow hue and stand out boldly against the greyish foliage. These flowers are neatly stacked in tiers, rising above the foliage on sturdy, upright stems, providing a tiered effect that's highly ornamental. The plant exudes a Mediterranean vibe and is commonly used in gardens for its striking contrast and ability to provide year-round interest without relying on a large stature to make a statement. The combination of architectural foliage and showy floral display makes Jerusalem Sage a popular choice for gardeners looking to add texture and color to their landscaping.

WaterJerusalem sage prefers dry to medium moisture levels and requires well-drained soil. It's important not to overwater, so allow the soil to dry out between watering sessions. In general, water approximately once a week with about 1 to 2 gallons depending on the climate and weather conditions; hotter, drier climates may necessitate more frequent watering. Reduce watering in the winter when the plant is dormant.
LightJerusalem sage thrives in full sun to partial shade conditions. The ideal spot for this plant is in an area where it can receive at least six to eight hours of direct sunlight daily. If grown indoors, place it near a south-facing window where it will get ample light.
TemperatureJerusalem sage is hardy and can tolerate a temperature range from around 10 to 80 degrees Fahrenheit. The ideal temperature for this plant is between 60 to 70 degrees Fahrenheit, which promotes healthy growth. Protect the plant from frost, as temperatures below 10 degrees Fahrenheit could damage or kill it.
PruningPruning Jerusalem sage helps maintain its shape and encourages more robust growth. Prune in late winter or early spring before new growth starts. Remove any dead or damaged stems and shape the plant as desired. Pruning can be done annually, or as needed to keep the plant looking its best.
CleaningAs needed
SoilJerusalem Sage prefers well-draining soil with a mix of one-third sand or gravel, one-third garden soil, and one-third compost, with a pH level around 6.5 to 7.5, which is slightly acidic to neutral.
RepottingJerusalem Sage should be repotted every 2-3 years in spring to refresh the soil and accommodate root growth.
Humidity & MistingJerusalem Sage prefers a dry climate and low humidity levels, making it ideal for arid and semi-arid regions.
Suitable locationsIndoor
Place Jerusalem Sage in a sunny spot with dry air.
Outdoor

Life cyclePhlomis lanata, commonly known as Woolly Jerusalem Sage, begins its life cycle as a seed that germinates in well-drained soil in spring. After germination, it develops into a small rosette of woolly, silver-green leaves at the soil surface. As the plant matures, it produces a woody base from which stems grow upwards and branch out, forming a mounding habit typically reaching up to 2 feet in height and spread. Throughout late spring to summer, Phlomis lanata blooms, showcasing whorls of yellow, hooded flowers on spikes above the foliage which are attractive to bees and butterflies. After pollination, seeds are produced which are then dispersed, completing its reproductive cycle. The plant is a perennial, so once established, it will continue to grow and produce flowers for several years before it may need division or rejuvenation to maintain its health and vigor.
PropogationPropogation time
Spring-Early Summer
The Jerusalem Sage, scientifically known as Phlomis lanata, can be propagated through both seed and vegetative methods, but the most popular method for propagation is by taking semi-ripe cuttings in the summer months. To do this, select healthy stems that have not yet become woody and cut a piece approximately 4 to 6 inches (about 10 to 15 cm) in length. The cut should be made just below a leaf node, as this is where root growth is most likely to occur. Remove the leaves from the lower half of the cutting to prevent moisture loss and avoid rot once planted. Then, dip the cut end in rooting hormone to encourage root growth, and insert the cutting into a pot filled with a mixture of peat and perlite. Keep the soil moist and in indirect sunlight until roots have established, which typically takes a few weeks. Once rooted, the cutting can be planted in its final location.
