Juniperus horizontalis 'Monber' (Ice Blue) - ienupar tarator

Juniperus horizontalis 'Monber' , also known as Ice Blue juniper , is a dwarf evergreen conifer cultivar in the Cupressaceae family, native to North America. It is noted for its dense, deep blue-green foliage and creeping habit, making it an excellent choice for ground cover, rock gardens, slopes, borders or containers. Its slow growth and decorative appearance make it ideal for modern landscapes and confined spaces.

Appearance of leaves, flowers and fruits

• Leaves : The foliage is composed of densely arranged soft needles and scales, a brilliant blue-green with silvery hues, especially in spring and summer. In winter, the foliage takes on purple-lead tones, adding seasonal interest. The needles are short, 3-5 mm, and form a fine, compact texture.
• Flowers : The flowers are insignificant, dioecious, appearing in spring in the form of small cones, yellow (male) or green (female). They have no ornamental value.
• Fruits : Cones are small, round, 5-8 mm, blue-black with a waxy bloom, maturing in 1-2 years. They are rare and do not contribute significantly to the decorative appearance.

Growth characteristics

• Height and width : Grows to 15-30 cm tall and 1.2-2 meters wide at maturity (after 10-15 years), forming a dense, creeping mat. It spreads horizontally, effectively covering the ground.
• Vigor : Slow growth, at a rate of 5-10 cm/year, making it ideal for spaces where a tidy appearance with minimal maintenance is desired.
• Type : Evergreen conifer with long, flexible branches that stretch along the ground, adhering well to surfaces.

Growing conditions

• Exposure : Prefers full sun (6+ hours/day) to maintain intense blue color. Tolerates partial shade , but foliage may become greener and less dense in low light.
• Soil : Grows in well-drained , sandy to loamy soils with a neutral to slightly acidic pH (5.5-7.5). Tolerates poor, rocky soils, and is drought tolerant once established. Does not tolerate waterlogged soils.
• Watering : Water moderately in the first few years, keeping the soil slightly moist. Once established, it is drought tolerant , requiring watering only during long periods of drought.
• Temperature : Hardy in zones 3-9 (down to -40°C), extremely suitable for temperate climates, including Romania. It tolerates cold, cold winds and urban pollution well.

Care and resistance

• Hardiness : Very resistant to cold, drought, salt and pollution, making it ideal for urban or coastal areas. Deer resistant, but may attract birds that eat the cones. Rarely affected by disease, but susceptible to root rot in poorly drained soils.
• Fertilization : Apply a balanced slow-release fertilizer (e.g. 10-10-10) in the spring, once every 2-3 years. It does not require frequent fertilization, especially in fertile soils.
• Pruning : Does not require extensive pruning due to slow growth. Remove dead or damaged branches in spring to maintain a neat appearance. Pruning for shaping is infrequent and should be done with care.
• Pests and Diseases : Resistant to most pests, but may be affected by mites or rust in wet conditions. Inspect regularly and use insecticidal soap or fungicides as needed.
• Fauna : The dense foliage provides shelter for small wildlife, and the cones attract birds.
