Not needed
  • water dropWater

    The Chalk Milkwort should be watered deeply but infrequently, allowing the soil to dry out slightly between waterings. Typically, this means watering the plant with about 1 gallon of water every week during the active growing season, depending on the climate and the size of the plant. During the winter months or in cooler climates, reduce watering to every other week or when the soil feels dry to the touch. It's important to avoid overwatering, as this can lead to root rot.

  • sunLight

    Chalk Milkwort thrives best in full sun to partial shade conditions. It should be placed in a spot where it receives at least 6 hours of direct sunlight each day, but can be protected during the hottest part of the afternoon if necessary. An east or west-facing location with bright, indirect light can also be suitable for encouraging flowering.

  • thermometerTemperature

    Chalk Milkwort prefers moderate temperatures and can handle a range between 50°F and 75°F. It can survive minimum temperatures of about 40°F, but should be protected from frost. The ideal temperature range for optimal growth is between 60°F and 70°F.

  • scissorsPruning

    Prune the Chalk Milkwort to maintain its shape and encourage bushier growth. Light pruning can be done in early spring or after the plant has finished flowering. Remove any dead or damaged branches, and trim back up to one-third of the plant's size to promote fresh growth. Pruning is typically needed once a year.

  • circleLife cycle

    The life of the Chalk Milkwort (Polygala calcarea 'Lillet') begins with seed germination, which typically occurs in spring when temperatures are suitable for growth. After sprouting, the seedling stage involves the development of roots and the first few leaves, allowing the plant to undergo photosynthesis and grow. Following this, the vegetative stage is characterized by the growth of stems, leaves, and root systems, as the plant matures and becomes more robust. The reproductive stage is marked by the production of vibrant flowers, usually from late spring to early summer, enabling pollination by insects. Once pollinated, the plant sets seeds that mature by late summer, completing its reproductive cycle. The plant then enters dormancy during the colder months, reducing its metabolic activity to survive winter, and re-emerges in the following spring to repeat the cycle.

    • Propogation time

      Spring-Early Summer

    • Propogation: Polygala calcarea 'Lillet', commonly known as the Chalk Milkwort, is often propagated from seed. The best time to sow seeds is in the spring after the last frost when the soil has warmed up. To propagate by seed, one must first sow the seeds in a well-draining soil mix, covering them lightly with soil as they need light to germinate. It's important to keep the soil moist but not waterlogged. Germination can be slow and irregular, sometimes taking several weeks to a few months. Once seedlings are large enough to handle, they can be carefully transplanted into individual pots and grown on until they are ready to be planted out in their permanent positions.
