  • water dropWater

    Bluebeard, or Caryopteris 'Grand Bleu', should be watered deeply once a week, providing about one to two gallons of water per plant each time, especially during its growing season in spring and summer. This amount may vary depending on your climate and the size of the plant. During the winter months, reduce watering as the plant goes dormant and its water needs decrease. Ensure that the soil around the Bluebeard has good drainage to prevent water logging. Overwatering can lead to root rot, so it's important not to let the soil remain saturated for prolonged periods.

  • sunLight

    Bluebeard thrives best in full sun conditions, meaning at least six hours of direct sunlight each day. This plant can manage in partial shade, but flowering will be less abundant. The ideal spot for your Bluebeard is in a south-facing garden that receives plenty of sunlight throughout the day.

  • thermometerTemperature

    Bluebeard prefers moderate temperatures and can typically tolerate conditions between 25°F and 85°F. They are hardy in USDA zones 5 through 9. The ideal temperature range for optimal growth and flowering is between 60°F and 70°F. Remember to provide adequate protection if temperatures are expected to drop significantly below freezing.

  • scissorsPruning

    Prune Bluebeard in late winter or early spring, removing old, spent flowers and about one-third of the top growth to encourage new growth and more prolific blooming. Pruning helps maintain a compact shape and improves the overall health and appearance of the plant. The best time for pruning Bluebeard is before new growth begins, typically when temperatures consistently stay above freezing.

  • broomCleaning

    As needed

  • bambooSoil

    Bluebeard (Caryopteris 'Grand Bleu') thrives in well-drained soil with moderate fertility; a mix of garden soil, compost, and sharp sand or perlite to improve drainage is ideal. The soil pH should be neutral to slightly acidic, around 6.5 to 7.2 for optimal growth.

  • plantRepotting

    Bluebeard generally does not require frequent repotting since it is more commonly grown as a perennial outdoor shrub; however, if grown in containers, repotting every 2-3 years in the spring can rejuvenate the plant and promote healthier growth.

  • water dropsHumidity & Misting

    Bluebeard prefers moderate humidity but is quite adaptable and can tolerate a range of humidity levels common in most outdoor environments, avoiding extreme wetness which can promote fungal diseases.

  • circleLife cycle

    Caryopteris × clandonensis 'Grand Bleu', commonly known as Bluebeard, begins its life cycle as a seed that germinates in spring when temperatures warm up. As a perennial plant, it then emerges from its root system each year with fresh growth of stems and leaves. Throughout spring and early summer, the plant focuses on vegetative growth, developing a bushy structure. By late summer to early fall, Bluebeard starts to flower, producing clusters of deep blue flowers that attract bees, butterflies, and other pollinators. After the flowering phase, as temperatures drop in late fall, the above-ground portions of the plant die back, and Bluebeard enters a period of dormancy during the winter. In the following spring, the cycle repeats, with the plant regenerating from its overwintering roots, provided it is grown in conditions that meet its hardiness requirements.

      Late Spring - Early Summer

    • The Bluebeard, scientifically known as Caryopteris × clandonensis Grand Bleu 'Inoveris' (PBR), is most commonly propagated through softwood cuttings. This method typically takes place in late spring or early summer when new growth is soft and pliable yet mature enough to handle cutting. To propagate, a gardener would take cuttings that are 4 to 6 inches long from healthy, non-flowering stems, strip the lower leaves, and dip the cut end in a rooting hormone. The prepared cutting is then inserted into a pot filled with a well-draining soil mix, ensuring that a few leaf nodes are below the soil surface. The cutting should be kept moist and placed in a warm area with dappled sunlight until it roots, which generally takes a few weeks. Once rooted, the new Bluebeard plants can be gradually acclimated to outdoor conditions before being planted in their permanent location.
