Jerusalem sage 'Edward Bowles'


Phlomis 'Edward Bowles', also known simply as Edward Bowles phlomis, is a striking perennial plant with an appearance that is both robust and architecturally interesting. Its stems are upright and square in shape, which is a characteristic common to members of the mint family, to which it belongs. The plant displays a profusion of sage-green leaves that are textured, heart-shaped at the base, and gently taper to a point at their tips. They often have a slightly wrinkled appearance and can be soft and hairy to the touch, giving them a somewhat velvety feel. Throughout its blooming season, Edward Bowles phlomis produces whorls of flowers that are tightly clustered together in tiers around the stems. These flowers are a delightful shade of pale yellow and are tubular with a lipped shape, typical of many plants favored by pollinators such as bees. The blooms provide a sharp contrast to the green foliage and can create a showy display that catches the eye in a garden setting. After the flowering period, the plant retains its structural interest as the flowers give way to seed heads that also cling to the stem in the same tiered fashion. These dry, brown seed heads can persist into the winter, offering visual interest even when the rest of the garden may be dormant. Overall, Edward Bowles phlomis has a bushy and informal habit that can complement a wide variety of garden styles, from cottage gardens to more modern, minimalistic landscapes.

  • water dropWater

    Jerusalem Sage should be watered deeply and infrequently to mimic natural conditions and encourage deep root growth. During the active growing period in spring and summer, water the plant once a week with approximately 1.5 gallons of water per session, depending on soil and weather conditions. In the fall and winter, reduce the frequency to once every two to three weeks, or as needed if the soil remains moist. Always check the soil moisture before watering; it should be dry an inch below the surface. Overwatering can lead to root rot, so err on the side of underwatering rather than overwatering.

  • sunLight

    Jerusalem Sage thrives in full sun, meaning it requires at least 6 hours of direct sunlight daily to perform its best. It can tolerate some light shade, especially in hot afternoon conditions, but too much shade will cause it to grow leggy and produce fewer flowers. The ideal spot for growing Jerusalem Sage is an area exposed to uninterrupted sunlight during the morning with some protection from the harsh late afternoon sun in extremely hot climates.

  • thermometerTemperature

    Jerusalem Sage prefers a temperate climate with temperatures ideally ranging between 60°F and 80°F. It is a hardy plant that can withstand minimum temperatures down to around 10°F, however, severe frost may damage the foliage. During the summer, Jerusalem Sage can endure temperatures up to the mid-90s°F without any significant problems as long as it is well-watered.

  • scissorsPruning

    Jerusalem Sage should be pruned to remove spent flower stalks and maintain a neat shape. Prune lightly in the fall after flowering to remove the old flowers, and then prune more heavily in late winter or early spring to encourage bushy growth and prepare for the coming growing season. Pruning every year will help prevent the plant from becoming woody and sparse.

  • circleLife cycle

    Phlomis 'Edward Bowles', commonly known as Jerusalem Sage, begins its life cycle from seed, which, when sown in spring or autumn, will germinate and grow into a young plant. As a hardy perennial, it develops a rosette of leaves in its first year, with hairy, sage-like foliage that remains evergreen in mild winters. In the second year, it matures and produces tall, sturdy stems topped with whorls of yellow flowers typically in late spring to early summer, attracting bees and butterflies. After flowering, seed heads may form if pollination occurs, which can either be collected for propagation or left to self-seed in the garden. Throughout its life, Phlomis 'Edward Bowles' will continue to expand its woody base, and with proper care, it can live for many years, although division every few years is recommended to maintain vigor. In winter, the plant may die back, especially in colder climates, only to resprout from the base come spring.

      Spring-Early Summer

    • Phlomis 'Edward Bowles', commonly known as Jerusalem Sage, can be propagated by cuttings, which is one of the most popular and effective methods. During the growing season, typically spring or early summer, semi-ripe stem cuttings can be taken. A cutting should have several leaf nodes and be about 4 to 6 inches (10 to 15 centimeters) long. After removing the lower leaves, the cut end of the cutting can be dipped into rooting hormone to encourage root development. The cutting should then be planted in a well-draining soil mix, and kept moist and warm until roots have developed, which can be verified by a gentle tug on the cutting after a few weeks. Providing a high humidity environment, such as covering with a plastic bag, can enhance rooting success. Once the cutting has rooted, it can be transplanted into its final location.
