Green Galtonia Galtonia viridiflora
ABOUT
Galtonia viridiflora, commonly known as the green-flowered galtonia, is a perennial plant featuring a striking appearance characterized by its elegant, bell-shaped flowers. The blooms exhibit a unique, greenish hue, which is quite uncommon among flowering plants. This notable color gives the plant its specific common name, alluding to the fresh, verdant shade of the flowers. The attractive blossoms are arranged gracefully along a spike, which ascends from the lush foliage below. The leaves of the green-flowered galtonia are typically long and strap-like, emanating from the plant's base in a dense, basal rosette formation. Their deep green color provides a lovely contrast to the lighter tone of the flowers above, augmenting the plant's overall appeal. Green-flowered galtonia is cherished by gardeners not only for its unusual floral hue but also for its ability to imbue gardens with a sense of verticality and elegance without overwhelming with its size. Furthermore, the plant's flowering season brings an added layer of interest to garden spaces, often becoming a focal point due to its distinctive coloration and floral shape.

WaterThe most common name for Galtonia viridiflora is Summer Hyacinth. This plant prefers a steady moisture level and should be watered once the top inch of soil feels dry. It's important to avoid over-watering as it may lead to root rot. In general, you can water your Summer Hyacinth with about 1 gallon of water per week during its growing season, though this may need to increase during hot, dry spells. During the dormant winter period, reduce watering significantly, only ensuring the soil doesn't completely dry out.
LightSummer Hyacinth flourishes best under full sun to partial shade conditions. It should be placed in a spot where it can receive at least 6 hours of direct sunlight each day. If planted outdoors, choose an area that is not shaded by taller plants or structures during the day.
TemperatureSummer Hyacinth is hardy and usually grows well in temperatures ranging between 50°F and 85°F. It can tolerate temperatures as low as 40°F, but extended periods below this can be harmful. The ideal temperature range for robust growth is between 60°F and 75°F.
PruningSummer Hyacinth doesn't typically require regular pruning, but deadheading spent blooms encourages further flowering. After flowering, removing flower stalks will keep the plant tidy. Pruning should be done right after the blooming phase finishes, generally in late summer or early fall.
CleaningAs needed
SoilSummer Hyacinth prefers a well-draining soil mix with good fertility and a neutral to slightly acidic pH of around 6.0 to 7.0. A combination of loamy garden soil, peat, and sand in equal parts can create an ideal environment for this bulbous plant. Ensuring adequate drainage while retaining some moisture is key to its healthy growth and blooming.
RepottingSummer Hyacinth bulbs should generally be repotted every 2 to 3 years to refresh the soil and provide space for bulb growth. It's best to repot after the flowering season when the leaves have died back, during the plant's dormant period.
Humidity & MistingSummer Hyacinth thrives best in moderate humidity levels; however, it is quite adaptable and does not require specific humidity conditions. Maintaining general indoor humidity will suffice for its growth.
Suitable locationsIndoor

Life cycleGaltonia viridiflora, commonly known as summer hyacinth, begins its life cycle as a bulb planted in well-drained soil in autumn or spring. Upon sprouting, it develops long, strap-like leaves that form a basal rosette. The plant enters its vegetative stage, focusing on leaf and root growth to gather energy. During the summer, the summer hyacinth undergoes its reproductive phase, producing tall spikes with bell-shaped, greenish-white flowers that attract pollinators for sexual reproduction. After pollination and flowering, the plant sets seed, which falls to the ground or is carried by the wind and animals to propagate the species. As the cold weather approaches, the foliage of the summer hyacinth dies back and the plant enters a dormancy period where the underground bulb survives until the next growing season.
PropogationPropogation time
Spring to Summer
Galtonia viridiflora, commonly known as summer hyacinth, is primarily propagated through bulb division. The best time to propagate summer hyacinth is in autumn, after the foliage has died back, indicating that the plant has entered dormancy. To propagate, carefully lift the clumps of bulbs and gently separate them, making sure that each divided section has at least one growth point. These sections can then be directly replanted in well-draining soil at a depth of about 5 inches (approximately 13 centimeters), spaced about 6 to 8 inches (15 to 20 centimeters) apart, to allow enough space for the new plants to grow. Water the newly planted bulbs thoroughly to establish them. This method is straightforward and helps to maintain the health of the clump by preventing overcrowding.
