Hypocalymma angustifolium, commonly known as White Myrtle, is a shrub native to the sandy soils and coastal heathlands of southwestern Australia. It typically grows up to 1.5 meters in height and features arching stems with narrow leaves. The plant is adorned with delicate white or white and deep pink flowers from June to October (early winter to mid-spring) in its native range, which coincide with the Australian winter and spring. The flowers are modest in size but can be quite showy when the shrub is in full bloom. White Myrtle is appreciated for its ornamental flowers and its ability to form a well-rounded bush, making it suitable for container growing and small garden spaces.

White Myrtle is valued for its versatility in cultivation, offering year-round greenery and seasonal flowering. It is often used in residential gardens for its attractive form and as a source of cut flowers for floral arrangements. The plant requires well-drained soil and prefers a position in partial shade, where it is protected from intense heat and wind. It has some frost resistance, which allows it to be grown in regions with mild winters. Regular pruning encourages bushy growth and helps maintain a lush appearance. In cultivation, it generally does best with low to medium water requirements and in soils with medium drainage. Despite its preference for partial shade, it can also tolerate full sun if watered adequately. Potential problems include damage from strong winds, which can cause the plant to become misshapen and expose bare wood.CC BY-SA 4.0
