WaterThe Perennial Flax, commonly known as Linum perenne, prefers moderate watering. During the growing season, water the plant when the top inch of soil feels dry, which could be about once a week, depending on the climate and weather conditions. Provide approximately half a gallon per watering for a medium-sized plant to ensure even soil moisture. During winter months, the plant requires less water, so reduce watering frequency to every other week or as needed. Overwatering can lead to root rot, so it's crucial to allow the soil to dry out slightly between waterings.
LightThe Perennial Flax thrives in full sun conditions where it can receive at least six to eight hours of direct sunlight daily. The ideal spot for this plant would be in a location that gets unfiltered sunlight throughout most of the day, ensuring that it's exposed to the strong light it needs to grow and bloom effectively. Avoid placing it in shaded areas, as this might impede its growth and flowering potential.
TemperaturePerennial Flax is quite hardy and can tolerate a temperature range from as low as 5°F to as high as 90°F. However, the ideal temperature for this plant is between 60°F and 70°F. It is important to keep the plant protected from extreme cold, as temperatures below 5°F could potentially damage or kill the plant.
PruningPruning Perennial Flax is important to encourage bushier growth and maintain a neat shape. Prune the plant in early spring before new growth starts. Deadheading or removing spent flowers regularly throughout the growing season can encourage more blooms. Pruning can be done annually, and if the plant looks tired or overgrown, cutting it back by a third can rejuvenate its appearance.
CleaningNot needed
SoilPerennial flax thrives in well-draining soil with a pH of around 6.0 to 7.0. A mix of loam, sand, and compost is ideal to foster healthy growth. Ensure the soil is rich in organic matter to support its vibrant blooms.
RepottingPerennial flax typically does not require frequent repotting. It can be left undisturbed for several years unless it outgrows its pot or the soil becomes depleted. Repotting every 2-3 years is usually sufficient for this hardy plant.
Humidity & MistingPerennial flax prefers moderate humidity levels but is quite adaptable to different environmental conditions. It doesn't require special humidity adjustments when grown outdoors.
Suitable locationsIndoor
Ensure bright light, well-draining soil, and minimal watering.
Outdoor
Plant in sunny spot, in well-draining soil, water sparingly.

Life cycleLinum perenne, commonly known as perennial flax, begins its life cycle when seeds germinate in the spring after experiencing a period of cold stratification. The seedlings develop into rosettes, forming a deep taproot that allows the plant to survive in dry conditions. In its first year, it focuses on vegetative growth, producing narrow, green leaves. Flowering typically occurs in the second year, with plants producing delicate blue or white flowers which are pollinated by insects, leading to the formation of fruit capsules containing seeds. After flowering, seeds mature and are dispersed from the parent plant, capable of germinating to produce new offspring. Perennial flax may live for several years, flowering annually, until it completes its lifespan and dies.

Spring
Blue flax, scientifically known as Linum perenne, is commonly propagated through seeds. The most popular method involves sowing the seeds directly outdoors, after all dangers of frost have passed, typically in the spring. To propagate blue flax, you should scatter the seeds over a well-drained soil bed and lightly cover them with about 1/8 inch (3 mm) of soil. It is also important to keep the soil moist until germination, which usually occurs in 14 to 21 days. Once seedlings are sturdy enough, thin them to stand 6 to 8 inches (15 to 20 cm) apart to allow for sufficient air circulation and growth space. This straightforward approach to seeding takes advantage of blue flax’s natural hardiness and helps to produce robust plants that can enhance gardens with their delicate blue flowers.
