Jerusalem Sage Information: How To Grow Jerusalem Sage In The Garden


By: Liz Baessler

Jerusalem sage is a shrub native to the Middle East that produces delightful yellow flowers even in drought conditions and very poor soil. It is an excellent choice for arid climates and hard to plant problem sites. Keep reading to learn more Jerusalem sage information, such as how to grow Jerusalem sage and tips for Jerusalem sage care.

Jerusalem Sage Information

What is Jerusalem sage? Jerusalem sage is a shrub that ranges natively from Turkey to Syria. Despite its name, it is actually a close relative of mint. The misnomer comes from the appearance of its leaves, which are pale green and soft, like those of a sage plant.

The shrub is evergreen in USDA zones 8-11, though it can be treated as a perennial in zones 7, 6 and, sometimes, zone 5. The growth will die back with the frost and grow back from the roots in the spring.

There are actually several species of Jerusalem sage, all of which fall under the family name Phlomis. The most popular is Phlomis fruticosa. This Jerusalem sage usually grows to a height and spread of 3-4 feet (1 m.).

In late spring and summer, it produces lots of bright yellow flowers on the upper ends of its stems. If the stems are promptly deadheaded, they will often flower a second time in the same growing season. If left on the plant, the flowers give way to attractive seed heads.

Jerusalem Sage Care

The key to growing Jerusalem sage is simulating its native Mediterranean climate. It is very tolerant of drought, and it needs extremely well-draining soil. It will appreciate fertile soil, but it also performs well in poor soil.

It can be propagated easily from seed, cuttings, or layering. It needs full sun, and will get leggy in the shade. It stands up very well to heat, and with its wide spread and bright colors is ideal for carrying over a flower garden through the hottest part of summer.

Jerusalem Sage (Salvia hierosolymitana) was a featured
Plant of the Day for June 26, 2018.

"Salvia hierosolymitana (Jerusalem sage) is a herbaceous perennial native to the eastern Mediterranean, with populations in Cyprus, Israel, Jordan, Lebanon, Syria, and the West Bank. It typically grows in open fields, rocky soils, and among low-growing native shrubs. It was first described in 1853 by botanist Pierre Edmond Boissier, with the epithet "hierosolymitana" referring to "royal, sacred Jerusalem".

It forms a mound of basal leaves that spreads to 2 feet, and slightly less in height. The ovate mid-green leaves are evergreen, lightly covered with hairs, and with a scalloped margin, growing 8-10 inches long with prominent veining underneath. The 1 inch or smaller flowers are a wine-red color, growing in widely spaced whorls, with 2-6 flowers per whorl. The lower lip is white, with wine-red spotting. The calyces are pea-green with red veins and bracts edged in red. The square stem of the 1 foot long inflorescences are also edged in red. Unlike many salvias, there is no odor when the leaves are crushed, and there is no known medicinal use of this plant."


Mistakes to Avoid when Growing Sage

Sage (Salvia officinalis)—also known as Common Sage, Culinary Sage and Garden Sage—is a perennial evergreen shrub found widely in the Mediterranean regions of the world. It belongs to the genus Salvia, which consists of over 900 varieties of shrubs, annuals and herbaceous perennials. This plant is used for its medicinal value and essential oil and also as a flavoring and seasoning ingredient. Its medicinal properties include the treatment of Alzheimer’s disease. This garden plant has gray leaves, wooden stems, and purple or blue flowers, which usually bloom in mid-summer. There are some common conditions that should be avoided while growing sage plants.

Improper transplantation

Sage plants can be transplanted using root cuttings or seeds. If seeds are used to propagate the plant, they should be sown while they are fresh. Sage plants do not grow easily with stored seeds and can establish slowly and unreliably even with fresh ones. For propagating this plant, root cuttings can be layered along the side branches so that they touch the soil.

Wet Soil

Sage needs a medium-wet soil that is well-dug and enriched with one or two handfuls of bone meal. The bone meal should be worked in at the start and end of the summer season. The soil bed should be well-drained for healthy growth of sage plants.

Inadequate Sunlight

Sage plants grow slowly until they are established. This plant requires maximum sunlight for a proper growth. A little shade is necessary if the plant is grown at higher altitudes where the exposure to the sun and hence the temperature is higher. When grown indoors, the plant should be placed near windows where it can receive direct sunlight. Sage plants are also found to grow well under fluorescent lamps.

Overwatering

The plant should be watered regularly. However, one must not overwater the plant, especially during summers. Sage plants tend to thrive best in a dry and sunny environment.

Overcrowding

Sage plants, like any other garden plant, should be well spaced. Overcrowding hampers plant growth as the neighboring plants compete for nutrients.

Tips for Plant Care

Sage plants must be protected from wind and frost, and should be pruned on a regular basis. Here are some useful tips for a proper growth of sage plants:

  • Protect the plant from frost: Frost damages sage plants. The best time to plant sage is before the onslaught of frost. It is advisable to grow the plants in containers and bring them indoors during winter.
  • Pruning: The plant should be pruned periodically for a healthy growth and also to avoid growth of woody stems. The plant should be pruned to almost half its size in the summers after the flowers have fallen.
  • Protect the plant from wind: Support rods (approximately 3 feet long) should be used with the plant to avoid weak stems from being blown away by the wind.
  • Harvesting: A sage plant should be harvested yearly after its establishment in the first year. The individual leaves can be dried and stored for seasoning and flavoring. Harvesting prevents the woody overgrowth of sage plants.


Plants You Might Want To Consider

So you’ve decided to make the plunge into water reduction landscaping? Fantastic! Let’s talk plants.

Many green, vibrant plants can be used in xeriscape easily. So too can some grasses. Shrubs are also an option. Do you like flowers? There are drought-tolerant flowering plants! You don’t have to make your garden into the Grand Canyon. It can be as lush and green as you want.

Here’s a sampling of a few of the many types of plants you can incorporate easily. All these xeriscape plants are tried and tested. For now, I’ll focus on the size of the plant, but remember, planning is key. Before you begin, select your plants not only by size, but by watering frequency and light needs.

Very Short (Under 1 Foot Tall)

Ground covers, fairy gardens, and more fall into the very short category. These diminutive options can be used in many ways for visual effect. I especially like these at the front of garden beds or in lieu of lawns.

Sedum rubrotinctum, ‘Pork And Beans’

Typically just under a foot tall, sedum rubrotinctum is a succulent. Nicknamed the jelly bean plant or pork and beans, its leaves are roughly bean-shaped. It produces its foliage on long, thick stems. In the spring, bright yellow star-shaped flowers appear. Best in zones 9-11.

Pachysandra procumbens, ‘Allegheny Spurge’

Allegheny spurge is a common ground cover plant. But did you know it can be used in xeriscaping, too? While it prefers moist soil when young, it’s fairly drought-tolerant when mature. It’s a shade lover as well, making it perfect for those odd spots without consistent sunlight. Zones 5-9 preferred.

Ophiopogon japonicus, ‘Dwarf Lilyturf’

Dwarf lilyturf, sometimes called fountain plant, is one of the tiniest plants on the list. Averaging at about 4″ in height, this little grass can be a ground cover or low-lying bed plant. It prefers damp soil but can take slightly-drier conditions once established. Best in zones 5-9.

Ophiopogon planiscapus, ‘Black Mondo Grass’

Seeking something darker? Consider black mondo grass. Like dwarf lilyturf, this lily relative develops tight, matted clumps of leaves. But in this case, the leaves are so dark in color they’re nearly black. Averages 8-12″ tall. Another great candidate for your shadier spaces! Zones 5-9.

Aloe aristata, ‘Lace Aloe’

Also called Aristaloe aristata, this plant isn’t a true aloe. It’s more closely related to other species. But its compact 6-8″ circles of sawtoothed spikes create a beautiful globe-like shape. It looks phenomenal in a garden setting, especially when it sends up orange flowers! Grow in zones 7-11.

Erigeron karvinskianus, ‘Santa Barbara Daisy’
