This comprehensive guide will provide you with all the information you need to cultivate this beautiful plant, from choosing the right location to ensuring its healthy growth.
Understanding Jerusalem Sage
Jerusalem sage, scientifically known as *Phlomis fruticosa*, is a deciduous shrub that belongs to the mint family. It’s native to the Mediterranean region and thrives in hot, sunny climates. Its common name, Jerusalem sage, is a bit of a misnomer, as it is not related to sage at all. The name likely originates from its resemblance to sage in terms of its foliage and the fact that it was introduced to Europe through Jerusalem.
Choosing the Right Location
Jerusalem sage prefers a sunny location with well-drained soil. It can tolerate partial shade, but full sun is ideal for optimal growth and flowering. The soil should be sandy or gravelly, allowing for excellent drainage. Avoid planting Jerusalem sage in areas with heavy clay soil, as it can lead to root rot.
Planting Jerusalem Sage
From Seed:
- Start Seeds Indoors: Sow seeds indoors 6-8 weeks before the last frost. Use a seed starting mix and place the seeds about ¼ inch deep in the soil. Keep the soil moist and warm, and expect germination in 10-14 days.
- Transplant Outdoors: Once the seedlings have developed a few sets of true leaves, harden them off by gradually acclimating them to outdoor conditions. Plant them outdoors in a sunny location, spacing them 2-3 feet apart.
From Cuttings:
- Take Cuttings: Take stem cuttings in the spring or summer. Choose healthy stems and cut them about 4 inches long. Remove the lower leaves and dip the cut end in rooting hormone.
- Root Cuttings: Plant the cuttings in a mixture of peat moss and perlite. Keep the soil moist and in a warm, bright location. Roots should develop within a few weeks.
From Purchased Plants:
- Choose Healthy Plants: Select healthy plants with vibrant green foliage and no signs of pests or diseases.
- Plant in Prepared Soil: Dig a hole twice the width and depth of the root ball. Amend the soil with compost or other organic matter to improve drainage. Place the plant in the hole and backfill with soil, ensuring the root ball is level with the ground.
Watering and Fertilizing
Jerusalem sage is drought-tolerant once established, but it does need regular watering, particularly during the first year after planting. Water deeply but infrequently, allowing the soil to dry out slightly between waterings. Avoid overwatering, which can lead to root rot.
Fertilize Jerusalem sage in the spring with a balanced fertilizer. You can also use a slow-release fertilizer to provide nutrients throughout the growing season. Avoid over-fertilizing, as it can lead to excessive leaf growth at the expense of flowering.
Pruning and Maintenance
Pruning Jerusalem sage is essential for maintaining its shape and promoting healthy growth. Prune it back in late winter or early spring before new growth emerges. Remove any dead or damaged stems and trim back the plant by about one-third. You can also prune it throughout the growing season to remove any leggy stems or to maintain a desired shape.
Protecting Jerusalem Sage from Pests and Diseases
Jerusalem sage is generally resistant to pests and diseases, but it can occasionally be affected by aphids, whiteflies, or powdery mildew. To prevent these issues, practice good garden hygiene, including removing any infected plant material. You can also use insecticidal soap or neem oil to control pests.
Enjoying the Beauty of Jerusalem Sage
The captivating purple blooms of Jerusalem sage appear in mid-summer and continue to flower until late fall. The flowers are a magnet for pollinators, attracting bees, butterflies, and hummingbirds to your garden. The silvery-green foliage adds a textural contrast to your garden beds, and the plant’s upright growth habit makes it an excellent choice for borders, mixed plantings, or as a focal point in your landscape.

Growing Jerusalem sage is a rewarding experience. Its striking blooms and beautiful foliage add a unique touch to any garden. Its drought tolerance and heat resistance make it an ideal choice for low-maintenance gardens. And its ability to attract pollinators makes it a valuable addition to your ecosystem.
