Syringa pubescens is a species of flowering plant in the lilac genus of the family Oleaceae, native to Korea and China (Gansu, Hebei, Henan, Hubei, Jilin, Liaoning, Ningxia, Qinghai, Shaanxi, Shandong, Shanxi, Sichuan).Growing to 6 m (20 ft) tall and broad, it is a substantial deciduous shrub with green leaves felted white beneath, and panicles of heavily scented, white-throated lilac flowers in early summer.The specific epithet pubescens means "downy", referring to the texture of the leaves.Three subspecies (formerly listed as separate species) are recognized : Syringa pubescens subsp. julianae - syn. S. julianae Syringa pubescens subsp. microphylla - syn. S. microphylla Syringa pubescens subsp. patula (also Syringa velutina) - syn. S. patula (Korean lilac, Manchurian lilac)The cultivar S. pubescens subsp. microphylla 'Superba' has gained the Royal Horticultural Society's Award of Garden Merit.According to some authorities Syringa meyeri C.K.Schneid. is a synonym of S. pubescens.

How to keep Syringa Pubescens.
Light
Juliana lilac is native to open areas, such as sunny meadows and forest margins, which provide plentiful light. It thrives in Full Sun but can also tolerate Partial Sun, adapting well to a range of sunlight conditions.
Water
Native to Eastern Asia, the Juliana lilac thrives in moderately moist soil and high humidity. It benefits from consistent watering, ideally twice a week, especially in the spring when it undergoes vigorous growth. Primarily grown outdoors, the Juliana lilac is valued for its ornamental qualities, displaying lush blooms when properly hydrated.
Temperature
Juliana lilac shows strong adaptability to a variety of climates, from scorching summers to cold winters. However, it does have a preferred temperature range for growth. When temperatures become too high, the plant is vulnerable to heat and humidity stress, which can cause it to die. In areas where temperatures approach the lower limit of its cold tolerance, it is important to use insulation to protect the plant.
Fertilizer
The timing of fertilizing Juliana lilac is important. Apply fertilizer in early spring and continue monthly until early summer. Fertilizer encourages attractive blooms and supplies energy during both dormant and active growth periods.
Pruning
The Juliana lilac boasts fragrant flowers and dense foliage. For best results, prune it in early spring by removing dead wood and thinning the branches to improve air circulation. Avoid heavy pruning; instead, opt for light annual pruning to maintain its shape and encourage flowering. Always make your cuts just above an outward-facing leaf bud to ensure optimal health and aesthetics.
