  • water dropWater

    Flax 'Gemmell's Hybrid', commonly known as perennial flax, should be watered deeply once a week, providing approximately 1 gallon of water per plant to encourage a deep root system. During hot, dry spells, watering frequency may need to increase to twice a week, ensuring the soil remains consistently moist but not waterlogged. It's crucial to avoid overhead watering to prevent fungal diseases, instead applying water directly to the base of the plant. Over the winter months, reduce watering since the plant requires less moisture when it's not in active growth.

  • sunLight

    For Perennial flax, the best light condition is full sun, meaning it should receive at least 6 hours of direct sunlight daily. It should be placed in a spot in the garden that ensures ample sunshine throughout the day, as this will promote the best flowering and healthy growth. Avoid overly shady areas which could hamper its development and bloom.

  • thermometerTemperature

    Perennial flax thrives in temperatures between 60 and 70 degrees Fahrenheit but can tolerate a range down to about 20 degrees and up to 90 degrees. The ideal growing conditions for Linum 'Gemmell's Hybrid' involve keeping it in an environment that avoids extreme cold and does not overheat, as too much heat can stress the plant.

  • scissorsPruning

    Perennial flax benefits from pruning mainly to remove spent flowers, which encourages further blooming and prevents the plant from self-seeding excessively. Pruning should be done immediately after the first flush of flowers has faded, typically in early summer. Light pruning can be performed as needed throughout the growing season to maintain shape and encourage additional flowering.

  • bambooSoil

    The perennial flax, including Linum 'Gemmell's Hybrid', thrives best in well-draining soil with added organic matter. A mix with loamy or sandy composition is ideal. Aim for a pH between 6.0 and 7.5. Amend with compost or peat moss to ensure fertility and good drainage.

  • plantRepotting

    Perennial flax, like Linum 'Gemmell's Hybrid', typically does not need frequent repotting. Repot every 2-3 years or if you notice signs of the plant outgrowing its pot, such as roots circling the container's base or poking out of drainage holes.

  • circleLife cycle

    Linum 'Gemmell's Hybrid', commonly known as a flax cultivar, begins its life as a seed, which, once sown and under suitable conditions of moisture and warmth, germinates and develops into a seedling. The seedling stage is marked by the growth of cotyledons and the beginnings of the first true leaves. As the seedling matures, it enters the vegetative stage, during which the plant experiences significant growth in size and form, producing the characteristic narrow leaves and stems. Following vegetative growth, the flax enters the flowering stage, producing blue or purplish flowers that are notable for their beauty. After successful pollination, typically by insects, the flowers develop into fruit capsules, usually containing several seeds. The life cycle completes when these seeds are mature and dispersed, ready to give rise to new plants the following growing season.

    • Propogation time

      Spring-Early Summer

    • Linum 'Gemmell's Hybrid', commonly known as a type of perennial flax, is most effectively propagated through seed. The ideal time for sowing flax seeds is in spring after the danger of frost has passed, ensuring that soil temperatures are conducive to germination. To propagate, seeds should be scattered over a well-draining soil mix and lightly covered with soil, no more than about 1/8 inch (approximately 3 millimeters) deep. The area should be kept moist but not waterlogged to encourage germination. Seeds typically sprout within 14 to 21 days. Once seedlings have developed several true leaves and have reached a sturdy stature, they can be transplanted to their final growing position in the garden, with spacing of about 12 inches (about 30 centimeters) to allow for adequate air circulation and growth.
