Aurora Balsam Poplar Populus × jackii 'Aurora' (f/v)
ABOUT
The plant known as the 'Aurora' is a type of hybrid poplar with a distinctive appearance. It presents a combination of vibrant green leaves that have a unique variegation with its edges commonly streaked in creamy white and hues of pale green. This variegation can be quite eye-catching, with the contrast of colors being most pronounced on the upper surfaces of the leaves, while the undersides may show a more subdued coloration. In spring and early summer, the foliage is especially attractive as the new growth emerges, creating a fresh and lively visual interest. The leaves are typically broad and somewhat triangular in silhouette, with a pointed tip and rounded base, resembling the classic heart or spade shape often associated with poplar trees. As the seasons change, the 'Aurora' maintains its decorative look, but the intensity of the variegation can be subject to fluctuating temperatures and sunlight exposure, making each specimen somewhat unique in its patterning. This deciduous tree bears its leaves on branches that spread outwards, creating an inviting canopy that can be quite lush during the peak growing months. Though not specifically discussing its size, it's worth noting that the overall form of the 'Aurora' presents an elegant and upright growth habit, with a branching structure that lends itself to a pleasing, somewhat pyramidal or rounded shape. The plant also produces catkins, which are long, pendulous clusters that add an additional texture to the tree's appearance. These can be observed in late spring or early summer, depending on the region and climate. Throughout the year, the 'Aurora' provides a dynamic visual display, with its ornamental leaves and distinctive variegation bringing a captivating aesthetic to any landscape in which it's planted, sans mentioning its dimensions.

WaterBalsam Poplar trees require consistent moisture, especially in their young and developmental stages. They should be watered deeply about once a week, providing around 1 to 2 inches of water which can be equivalent to approximately 15-30 gallons for a young tree, depending on its size and the weather conditions. During hot, dry periods, waterings may need to be increased to twice a week. It is important to avoid waterlogging, so ensuring proper drainage is essential. Mulching can help maintain soil moisture and reduce the frequency of watering.
LightBalsam Poplar trees thrive in full sunlight, where they can receive at least 6 hours of direct sunlight daily. The best spot for planting a Balsam Poplar is in an open space, away from buildings or other trees that might cast shade on it. Avoid planting in heavily shaded areas as this can hinder its growth and overall health.
TemperatureBalsam Poplars are hardy and can survive in temperatures as low as -40 degrees Fahrenheit and as high as 100 degrees Fahrenheit. However, the ideal temperature range for this tree is between 50 to 75 degrees Fahrenheit. They are best suited for planting in USDA hardiness zones 2 to 9 and can withstand significant temperature fluctuations.
PruningBalsam Poplar trees should be pruned to maintain shape and promote healthy growth, removing any broken or diseased branches as needed. The best time to prune is during the dormant season, late winter to early spring, before new growth starts. Prune every 3 to 5 years to give the tree a chance to fill out naturally and to minimize stress from cutting.
CleaningAs needed
SoilThe Balm of Gilead prefers a well-drained, loamy soil rich in organic matter with a pH range of 6.0 to 7.5. A balanced mix of sandy loam, peat, and compost works well, promoting good root growth and drainage.
RepottingBeing a large and fast-growing tree, the Balm of Gilead rarely needs repotting as it is primarily planted outdoors. Instead, it requires ample space to grow and may be transplanted to suit landscape changes.
Humidity & MistingThe Balm of Gilead thrives in moderate to high humidity levels typical of its natural habitat, although it is adaptable to various humidity conditions when grown outdoors.

Life cycleThe common name for Populus × jackii 'Aurora' is Balm of Gilead. Its life cycle begins with seed germination, where the tiny seeds, often dispersed by wind due to their light and fluffy nature, land in fertile, moist soil and begin to sprout. These seedlings quickly develop into young saplings, showing rapid growth characteristic of the genus Populus. As saplings mature into adult trees, they may reach substantial heights and are characterized by their straight trunks and spreading branches. During spring, Balm of Gilead produces catkins, which are the flowering structures necessary for pollination and subsequent seed production. As they age, the trees eventually reach the senescence stage, where growth slows and they become susceptible to environmental stresses, pests, and diseases, leading to their eventual decline and death.
PropogationPropogation time
Spring-Early Summer
The Populus × jackii 'Aurora', commonly known as the Aurora Balsam Poplar, is most effectively propagated through hardwood cuttings. The best time to take these cuttings is in late winter when the tree is dormant, generally from January to March. To make a cutting, select a healthy, disease-free branch and snip a 6 to 8-inch (approximately 15 to 20 centimeters) length. The cutting should have at least a couple of nodes where leaves attach as these are potential growth points. The base of the cutting is then dipped in rooting hormone to encourage root development and planted in a well-draining soil mix. It’s crucial to keep the soil moist but not waterlogged to prevent the cutting from rotting. Under the right conditions, roots will begin to form in a few weeks, and the new plant can eventually be transplanted outdoors.
