Origin
Zaluzianskya maritima (L.f.) Walp. var. grandiflora Hiern, commonly known as Night Phlox, is a species of flowering plant found in South Africa and belongs to the Caprifoliaceae family.
Common Names
The plant is widely known as Night Phlox and Sea Brookweed. The Afrikaans common name is Nagoggendblom.
Uses
The plant is mostly cultivated for ornamental purposes. Its fragrant blooms are popular with gardeners who enjoy its sweet scent and its uniqueness as a night-blooming plant. The blooms are also used in flower arrangements. Traditional medicine practitioners use the plant for its medicinal properties in treating rheumatism and toothaches.
General Appearance
Zaluzianskya maritima (L.f.) Walp. var. grandiflora Hiern is a low-growing, herbaceous perennial that forms small clumps, usually growing up to 12 inches in height. Its leaves are ovate and grayish-green, and they grow up to 1.25 inches long. Its flowers bloom in clusters, have a trumpet-shaped corolla, and come in various colors, including white, pink, and purple. The plant blooms from late spring through summer, emitting a sweet fragrance at night.
Light Requirements
Zaluzianskya maritima var. grandiflora prefers full sunlight to partial shade. In areas with high temperatures, partial shade can be provided during the hottest part of the day to avoid stress on the plant. However, too much shade can lead to reduced flowering and weaker growth.
Temperature Requirements
This plant can tolerate a wide range of temperatures but performs best in moderate temperatures. The optimal temperature for growth and flowering ranges from 15°C to 25°C. Consistently high temperatures above 30°C can cause stress and lead to decreased growth. In areas with colder temperatures, this plant can tolerate temperatures as low as -5°C if it is provided with protection.
Soil Requirements
Zaluzianskya maritima var. grandiflora prefers well-draining soils that are rich in organic matter. The soil should be moist but not waterlogged as waterlogging can lead to root rot. The plant can tolerate soils with a wide range of pH, from slightly acidic to slightly alkaline. To improve soil fertility, organic matter such as compost can be added. In areas with poor soil, regular fertilization can be provided during the growing season to promote healthier growth.
Cultivation Methods
Zaluzianskya maritima (L.f.) Walp. var. grandiflora Hiern, commonly called Night Phlox, is a low-maintenance plant that is relatively easy to cultivate. This plant requires well-draining soil and full sun or partial shade for optimal growth.
It is native to coastal dunes of southern Africa and is accustomed to sandy soil, so it is best to provide it with a well-draining soil that is slightly acidic or neutral. Adding organic matter to the soil can help improve its fertility and water retention capacity.
Watering Needs
Though Night Phlox is tolerant of drought, it is essential to water it regularly to promote healthy growth. Watering the plant thoroughly once a week should be sufficient in normal weather conditions. In extreme heat and drier weather conditions, watering up to twice a week is recommended. However, avoid overwatering, as this plant is susceptible to root rot in waterlogged soil.
Fertilization
Fertilizing Night Phlox can promote healthier growth and increase flower production. It is best to fertilize this plant during the growing season, which is late spring to early fall. Use a balanced liquid fertilizer every two to three weeks, following the manufacturer's instructions carefully. Avoid fertilizing the plant during the winter dormancy period.
Pruning
To maintain the plant's shape and control its size, it is necessary to prune Night Phlox. Pruning should take place in the early spring before the new growth begins. Cut back the stems by one-third of their length, and remove any damaged or diseased limbs. Regular pruning encourages the production of new growth, resulting in a fuller and healthier plant.
Propagation of Zaluzianskya maritima (L.f.) Walp. var. grandiflora Hiern
Zaluzianskya maritima (L.f.) Walp. var. grandiflora Hiern, commonly known as Night Phlox, is an incredibly beautiful plant that delights gardeners with its fragrant, white flowers that bloom early in the evening. Propagating Night Phlox is relatively easy, and there are various methods you can use to propagate it successfully.
Propagation by Seed
The easiest and most popular way to propagate Night Phlox is by seed. Collect seeds from mature plants after they have flowered, or purchase them from a reputable supplier. Sow the seeds in a propagator or tray filled with moist seed compost, then sprinkle a thin layer of compost over the top and water gently. Keep the seeds at a temperature of around 18-20°C and ensure the compost remains moist. After about 2-3 weeks, the seeds should start to germinate, and you can transplant them into individual pots. It takes 3-4 months for the plants to establish themselves before they can be planted outdoors.
Propagation by Cuttings
You can propagate Night Phlox by cuttings from non-flowering softwood shoots. Choose a healthy-looking shoot and take a cutting that's around 5-10cm long. Remove all the leaves from the lower half of the cutting, leaving just a few at the top. Dip the cut end of the stem in rooting hormone powder and plant the cutting in a pot filled with well-draining potting soil. Water it gently and cover the pot with a plastic bag to create a humid environment. Keep the cutting well-watered but not waterlogged and maintain a temperature of around 20-25°C. In about 3-4 weeks, roots should start to form, and the cutting should be ready to transplant into individual pots.
Propagation by Division
Propagation of Night Phlox through division works best for established plants that have been growing for at least two years. Dig up the plant during the dormant season (in late autumn or early spring) and separate the clump into smaller divisions using a sharp spade or knife. Ensure each division has a healthy root system and replant in well-prepared soil. Water the new plants and keep them well-mulched to ensure they establish well.
Disease and Pest Management for Zaluzianskya maritima var. grandiflora
Zaluzianskya maritima var. grandiflora is a hardy plant that is relatively resistant to common pests and diseases. However, it is not entirely immune to these issues, and proper management is necessary to keep the plant healthy and flourishing.

To manage pest infestations, it is essential to monitor the plants regularly for any signs of infestation. This can include checking for visible insects, webbing, or discoloration of leaves. In case of pests, it is recommended to use insecticidal soaps or oils, neem oil, or other natural remedies to control the problem.
Diseases
The most common diseases that may affect Zaluzianskya maritima var. grandiflora include fungal leaf spots and root rot. Fungal leaf spots can cause brown or black spots on the leaves, which can ultimately lead to leaf drop. Root rot can cause the plant to wilt and eventually die.
To manage fungal diseases, it is important to ensure that the plant has adequate air circulation, avoid overhead watering, and remove any dead or diseased plant material. Fungicides may also be used to control the problem. As for root rot, the best course of action is to improve the drainage of the soil and avoid overwatering the plant.
Regular inspection and proper management can help keep Zaluzianskya maritima var. grandiflora healthy and thriving, with minimal pest and disease issues.
