Dodonaea viscosa
ABOUT
The plant commonly known as hopbush is recognized by its shiny, lance-shaped leaves that cluster along its branches, often taking on a leathery texture. The foliage can display a range of hues, from bright green to a purple or reddish tint, changing with the seasons or varying environmental conditions. This hardy shrub is adorned with small, inconspicuous flowers that may be green or yellow, sometimes with a purplish cast. These flowers give way to distinctive winged fruits, or samaras, which resemble the hops used in brewing beer, hence the common name 'hopbush'. The fruit typically starts out green and ripens to a papery texture, often turning reddish-brown or purplish, adding to the ornamental value of the plant. The overall form of the hopbush is dense and bushy, with a graceful, somewhat spreading habit that can create a lush appearance in the landscape. Its adaptability to various conditions and the attractive, persistent fruits make it a popular choice for gardeners looking for a resilient and decorative addition to their plantings.

WaterThe Hop Bush, or Dodonaea viscosa, prefers dry conditions and should only be watered moderately. In general, water the Hop Bush once every 7 to 14 days, providing 1 to 2 gallons per watering depending on the size of the plant and the local climate. Less water is needed during the winter or when rain is frequent. Always allow the top few inches of soil to dry out before watering again to avoid overwatering and potential root rot. It is crucial to avoid stagnant water around the roots, so ensure the plant has good drainage.
LightHop Bush thrives best in full sun to partial shade conditions. For optimal growth, place the plant in a location where it will receive at least 6 hours of direct sunlight daily. The Hop Bush is adaptable and can tolerate some shade, but its foliage and flowering may be less vigorous in lower light situations.
TemperatureHop Bush can tolerate a wide range of temperatures, generally surviving between 20°F to 100°F. However, the ideal temperature range for this plant is between 60°F and 85°F. While the Hop Bush is quite resilient and can withstand occasional temperature extremes, it's best to avoid sustained exposure to conditions below freezing to prevent damage.
PruningThe Hop Bush should be pruned to maintain shape, remove dead or damaged branches, and encourage denser foliage. Pruning is best done in late winter or early spring before new growth begins. Light pruning can be performed yearly, while more substantial cuts should be done as needed, typically every 2 to 3 years. Always use sharp, sterile pruning tools to make clean cuts.
CleaningAs needed
SoilHop Bush thrives in well-draining soil with a pH range of 6.5 to 7.5. A mix of loam, sand, and some organic matter will create an ideal growing medium for the plant. Keeping the soil aerated and ensuring good drainage is pivotal for the health of the plant's root system.
RepottingHop Bush does not require frequent repotting and can be done every 2-3 years, or when the plant has outgrown its current pot. Repotting is best done during the spring or early summer when the plant is actively growing.
Humidity & MistingHop Bush is adaptable to various humidity levels but prefers a moderate range. It doesn't require high humidity and can do well in the average atmospheric moisture levels found in most homes and outdoor environments.

Life cycleHopbush (Dodonaea viscosa) begins its life cycle with seed germination, typically after the seeds have undergone a period of dormancy and are exposed to favorable conditions such as moisture and warmth. Seedlings emerge and establish a root system, while shoots develop into young plants. As hopbush matures, it develops woody stems and a robust foliage characterized by lance-shaped leaves with a leathery texture. The plant flowers, usually in clusters, producing small, inconspicuous flowers that may be either male, female, or hermaphroditic, depending on the plant variety. After pollination, hopbush produces papery, winged seed capsules that dry and split open to release seeds. This hardy shrub can also spread vegetatively through root suckers, allowing it to form dense stands or thickets.
PropogationPropogation time
Spring to Summer
Propogation: The most popular method of propagation for Hopbush (Dodonaea viscosa) is by seed. This plant tends to produce seeds towards the end of summer or the beginning of fall, which is the ideal time for seed collection and sowing. Once collected, the seeds require pretreatment to break dormancy. This is typically done by soaking them in hot water at approximately 194 degrees Fahrenheit (90 degrees Celsius) and then letting them cool for 24 hours. After the seeds have swollen, which usually indicates successful breaking of dormancy, they can be sown in a well-draining soil mix. Germination occurs best at temperatures around 68 to 86 degrees Fahrenheit (20 to 30 degrees Celsius). Seedlings can be expected to emerge in a couple of weeks and should be grown on in individual pots before being planted out into their final position once they've established a strong root system.
