ABOUT
Elaeagnus pungens 'Goldrim', commonly known as the variegated silverberry, is an eye-catching evergreen shrub. This ornamental plant is distinguished by its unique foliage, which exhibits a combination of dark green, light green, and golden yellow hues. The leathery leaves of the variegated silverberry are broad and oval-shaped, often with wavy or somewhat spiked margins that add a textured appeal to the overall appearance. The edges of the leaves are highlighted with an irregular golden yellow border, creating a striking contrast that makes 'Goldrim' a standout variety. Throughout the year, the glossy leaves maintain their vibrant coloration, catching the light and providing visual interest in garden settings. The plant also produces small, silvery-white to brownish flowers that are subtly fragrant. The flowers add another layer of appeal, although they tend to be less conspicuous against the bold variegated foliage.

WaterThe Thorny Elaeagnus should be watered deeply but infrequently to encourage strong root development, and the soil should be allowed to dry out slightly between watering. Typically, watering once a week is sufficient, but this may need to be adjusted depending on local climate, weather conditions, and soil type. During hot and dry periods, increase watering frequency to every 3-4 days. A good rule of thumb is to provide about one to two gallons of water, ensuring it penetrates the soil to a depth of at least 8-10 inches to reach the root zone.
LightThorny Elaeagnus thrives in full sun to partial shade, so planting it in a spot that receives at least 4-6 hours of direct sunlight per day is ideal. It can also tolerate high levels of light but might require additional watering in these conditions. The plant's variegated leaves will be more vibrant with exposure to bright light, though too much shade can lead to less pronounced variegation.
TemperatureThorny Elaeagnus is tolerant of a wide range of temperatures, but it grows best when the temperature is between 60°F and 80°F. It can survive minimum temperatures down to about 0°F and maximum temperatures well above 100°F, making it a versatile shrub for different climate zones. Avoid exposure to extreme cold winds and frost which can damage the foliage.
PruningPruning Thorny Elaeagnus is essential to maintain a desirable shape and to encourage healthy, dense foliage. The plant can be pruned in late winter or early spring before new growth begins. It tolerates heavy pruning if shaping is required, but generally, light trimming to remove dead or damaged branches and to shape the plant is usually enough. Pruning can be done annually or as needed to keep the plant looking tidy.
CleaningAs needed
SoilThorny elaeagnus ('Goldrim') prefers well-draining soil with a mix of two parts loam, one part sand or perlite, and one part compost. The optimal soil pH is slightly acidic to neutral, around 6.0 to 7.0, to promote healthy growth.
RepottingThorny elaeagnus ('Goldrim') generally requires repotting every two to three years. If growth appears to be slowing or the roots are becoming pot-bound, it is time to repot into a slightly larger container.
Humidity & MistingThorny elaeagnus ('Goldrim') is adaptable to various humidity levels, but it thrives best in moderate humidity. Aim for a humidity level around 40-50% for optimal plant health and comfort.
Suitable locationsIndoor
Place in bright, indirect light and water when soil is dry.
Outdoor
Plant in well-draining soil, partial sun, and shelter from harsh winds.

Life cycleElaeagnus pungens 'Goldrim', commonly known as Thorny Olive, begins its life as a seed, which, under suitable conditions of warmth and moisture, germinates to produce a seedling. The seedling stage is marked by the emergence of the first roots and shoots, which will develop into a young plant. As the plant matures, it enters the vegetative stage, characterized by rapid growth of leaves, stems, and branches; the 'Goldrim' variety is noted for its variegated leaves with yellow and green coloring. Over time, the plant will reach reproductive maturity and enter the flowering stage, which sees the production of small, fragrant, silvery flowers, usually in late fall to winter. Following pollination, often assisted by birds and other wildlife, these flowers develop into fruit, a drupe that contains a single seed and is attractive to birds, thus aiding in seed dispersal. The plant completes its life cycle when it senesces and eventually dies, having potentially produced many offspring through its seeds over many years.
PropogationPropogation time
Spring-Early Summer
Elaeagnus pungens 'Goldrim', commonly known as variegated thorny elaeagnus or silverthorn, is often propagated by semi-hardwood cuttings. This method is typically undertaken in late summer when the current year's growth has begun to mature and harden off, but isn't yet fully hardened like it would be in winter. Cuttings of about 4 to 6 inches in length (10 to 15 centimeters) should be taken from healthy, disease-free branches. The lower leaves are then stripped off, and the base of the cutting is dipped in a rooting hormone to encourage root growth. Afterward, the cutting is inserted into a well-draining soil mix and kept under high humidity and consistent warmth, but not in direct sunlight. It usually takes several weeks for the cuttings to root successfully.
