Common names
Watsonia bulbillifera J.W.Mathews & L.Bolus is commonly known as the Bulb-bearing Watsonia or Bulbil Watsonia.
Appearance
Watsonia bulbillifera J.W.Mathews & L.Bolus is a perennial plant that grows to a height of 0.5-1.5m. It has slender, erect stems that are green in color and are covered with long, narrow leaves that are up to 90cm long. The plant produces large, showy flowers that are pink, orange, or red in color and are carried on tall spikes that can reach up to 2m in height. The flowers are trumpet-shaped and have six petals, with the upper three petals forming a distinct hood.
Uses
Watsonia bulbillifera J.W.Mathews & L.Bolus is primarily grown as an ornamental plant, and its vibrant flowers make it a popular choice for gardens and cut flower arrangements. However, the plant has also been used for medicinal purposes by some indigenous communities in South Africa. The bulbils produced by the plant are edible and have been used as a food source by these communities as well.
Light Requirements
The Watsonia bulbillifera generally requires full sunlight to grow. The plant needs at least six to eight hours of direct sunlight per day. Placing the plant in a shaded area can restrict its growth, as it cannot receive enough light to photosynthesize and produce food.
Temperature Needs
The plant is native to South Africa and typically grows well in warm temperatures. The ideal temperature range for Watsonia bulbillifera is between 60-75 degrees Fahrenheit (16-24 degrees Celsius), which is typical of most areas during the spring and summer months. Lower temperatures can cause the plant to slow down its growth or become dormant, while higher temperatures can cause the plant to become dehydrated and wilt.
Soil Requirements
Watsonia bulbillifera thrives best in well-draining soil that is rich in organic matter. A pH range between 6.0 and 7.0 is ideal for the plant's growth. The plant does not tolerate waterlogged conditions, so it is important to ensure the soil provides adequate drainage for excess water to escape. The ideal soil texture for the plant is sandy loam, which can retain some moisture while still providing adequate drainage. Adding organic matter, such as compost or aged manure, can help to improve soil texture and nutrient availability.
Cultivation methods
Watsonia bulbillifera J.W.Mathews & L.Bolus is a perennial plant that thrives in full sunlight and well-drained soil. It grows best in USDA hardiness zones 8-10.
Plant the bulbs of Watsonia bulbillifera in the spring (after the last frost) or fall (before the first frost). The planting hole should be about 6 inches deep and 4-5 inches wide. Plant the bulbs 5-6 inches apart from each other and cover them with soil. Water the bulbs immediately after planting.
Watering needs
Watsonia bulbillifera requires regular watering during the growing season. Water the plant deeply but infrequently. The soil should be moist but not waterlogged. Overwatering can lead to root rot and other fungal diseases.
During the dormant season, reduce the watering frequency. Water the plant only when the soil is completely dry. Frequent watering during the dormant season can cause the bulb to rot.
Fertilization
Watsonia bulbillifera thrives in fertile soil. Before planting, amend the soil with compost or well-rotted manure.
During the growing season, fertilize the plant every 2-3 weeks with a balanced fertilizer. Follow the manufacturer's instructions for the application rate.
Pruning
Pruning Watsonia bulbillifera is not necessary. Remove the dead flowers and stems as they appear to keep the plant tidy.
After the flowering season, leave the foliage intact until it turns yellow and dies back naturally. The foliage provides nutrients to the bulb for next year's growth.
Propagation of the Watsonia bulbillifera J.W.Mathews & L.Bolus plant:
Watsonia bulbillifera J.W.Mathews & L.Bolus is a stunning plant native to South Africa. It is a member of the iris family, and it produces showy spikes of large, funnel-shaped flowers that come in shades of pink, orange, and red. If you have this plant in your garden and wish to propagate it, you'll be pleased to know that the process is relatively easy.

Offsets:
Watsonia bulbillifera J.W.Mathews & L.Bolus also produces small bulbils, or offsets, around the base of the parent plant. These bulbils can be removed and planted in pots or directly in the ground. Make sure the soil is well-draining, and place the bulbil in a hole that is two to three times its size. Cover the bulbil with soil, watering lightly, and keep it moist until new growth appears.
Seed propagation:
Although seed propagation is possible, it is not commonly used for Watsonia bulbillifera J.W.Mathews & L.Bolus. The seeds can be sown directly in the ground or in a pot in the autumn. Cover the seeds with a thin layer of soil, and keep them moist. Germination can take several weeks.
