White Guernsey Lily Nerine undulata (Flexuosa Group) 'Alba'
ABOUT
Nerine undulata 'Alba', often referred to as white nerine, is a bulbous perennial that exhibits a striking appearance. As suggested by the name 'Alba', this variety is characterized by its alluring white flowers. Each bloom is shaped like a slender trumpet, elegantly undulated at the margins, giving a ruffled look that adds to the charm of the plant. The flowers are typically arranged in an umbel-like cluster at the top of a leafless stem, giving the impression of a delicate bouquet held aloft. This cluster hosts several individual flowers, each contributing to a display that's both eye-catching and ornamental. The petals possess a glistening quality, often described as being lustrous or shimmering in light, enhancing their visual impact. Below these striking blooms, the foliage is narrow and strap-shaped, usually presenting a deep green color that contrasts nicely with the bright white of the flowers. These leaves may also feature a hint of arch, adding to the overall gracefulness of the plant. White nerine blooms in the fall, providing an exceptional display when many other plants are starting to decline after the summer growth period. With its distinctive floral presentation, the white nerine can be an elegant addition to gardens and is often used as a cut flower due to its long vase life.

WaterFor the Guernsey Lily, during the growing season (spring to autumn), water it thoroughly, ensuring the soil is damp but not waterlogged. Typically, watering once a week with about 20 ounces (0.15 gallons) should suffice. Allow the top inch of soil to dry out between waterings. Decrease watering frequency after the leaves die back in autumn, and during its dormant winter period, keep the soil mostly dry to prevent bulb rot. Overwintered bulbs may only need watering once every few weeks, if at all, depending on humidity levels.
LightThe Guernsey Lily thrives best in full sun or partial shade conditions. An ideal spot would be one that receives direct sunlight for several hours each day, especially in the morning with some light afternoon shade in hot climates. Avoid deep shade, as insufficient light can lead to poor flowering.
TemperatureThe Guernsey Lily prefers moderate temperature conditions and can survive in temperatures as low as 40 degrees Fahrenheit to a maximum of around 90 degrees Fahrenheit. The ideal growing temperature range for the plant is between 60 and 75 degrees Fahrenheit. Temperature extremes beyond this range can be detrimental to the plant's health.
PruningPruning of the Guernsey Lily is primarily for removing spent flowers and yellowing leaves. Deadhead the flowers after blooming to encourage more blooms. Pruning is not frequently required, except to maintain appearance and remove old foliage at the end of the season. The best time for general cleanup is late fall or early winter after the leaves have died back.
CleaningAs needed
SoilGuernsey Lily thrives in well-draining, sandy soil enriched with organic matter; a pH range of 6.0 to 7.5 is ideal for this plant.
RepottingGuernsey Lilies should be repotted every 3 to 5 years to refresh the soil and divide the bulbs if necessary.
Humidity & MistingGuernsey Lily prefers moderate to high humidity levels but is adaptable to typical household humidity conditions.
Suitable locationsIndoor
Place in bright light avoiding direct sun; water sparingly in growth.
Outdoor
Plant in full sun to partial shade with shelter from strong winds.

Life cycleThe life of the White Nerine (Nerine undulata 'Alba') begins with a dormant bulb which, upon sensing the appropriate seasonal conditions, initiates growth of foliage and stems. The plant's foliage, consisting of strap-like leaves, emerges in late winter or early spring and remains active throughout the growing season. Flower stalks develop in late summer to early autumn, bearing clusters of wavy-edged, trumpet-shaped, white flowers that are particularly ornamental. After flowering, the plant sets seeds which can be dispersed to produce new plants, though propagation is more commonly achieved by dividing the bulbs. Post-bloom, the foliage gradually dies back as the plant enters dormancy during winter, conserving energy within the bulb. This dormant period is crucial in the White Nerine's cycle, allowing it to survive adverse conditions until the next growth cycle begins with the return of suitable environmental factors.
PropogationPropogation time
Spring to Summer
The most popular method for propagating Nerine undulata, commonly known as Guernsey Lily, is through division of its bulbs. This is typically done in late summer after the foliage has died back. Carefully unearth the clump of bulbs and gently pry them apart to separate the offsets from the parent bulb. Ensure that each offset has a portion of the basal plate to foster root development. Plant the offsets about 4 to 6 inches (approximately 10 to 15 centimeters) deep and spaced 6 to 8 inches (approximately 15 to 20 centimeters) apart in well-draining soil and in a location that receives full sun. Water the offsets thoroughly after planting. They will usually flower after a couple of years when they have developed a sufficiently large bulb.
