Pruning
  • water dropWater

    The Cardinal Flower should be watered deeply and the soil allowed to partially dry out between waterings, so thorough weekly watering is recommended. Watering should provide approximately 1 inch of water each week, meaning a garden with an area of 10 square feet would require about 6 gallons weekly. The amount of water can be adjusted during periods of high heat or drought, when the plant may need more frequent watering. It's important to avoid overwatering to prevent root rot, so ensure the plant is in well-draining soil.

  • sunLight

    For Cardinal Flower, the best lighting condition would be a spot that receives full sun to partial shade. This plant thrives with morning sunlight and some afternoon shade, as intense, direct sunlight in the hottest part of the day might stress the plant, especially in southern climates.

  • thermometerTemperature

    Cardinal Flowers prefer temperate conditions and can tolerate a range between 60°F and 75°F as ideal growing temperatures. They can survive minimum temperatures just above freezing, around 35°F, and maximum temperatures up to about 90°F, but prolonged exposure to extremes can damage the plant.

  • scissorsPruning

    Pruning Cardinal Flower involves deadheading the spent blooms to promote further flowering and prevent self-seeding if undesired. Cut back the foliage in late fall or early spring to encourage new growth and maintain plant health. This plant benefits from occasional pruning throughout the growing season to shape the plant and remove any damaged or yellowing leaves.

  • circleLife cycle

    The life cycle of Lobelia × speciosa 'Hadspen Purple' begins with seed germination, occurring in warm, moist soil conditions in spring. Once the seedlings emerge and establish, they grow rapidly to form a rosette of basal leaves. Throughout the growing season, the plant develops tall flowering spikes with vibrant purple flowers that attract pollinators and bloom from midsummer to early autumn. After pollination, seeds are produced and dispersed, completing the reproductive cycle. In colder climates, 'Hadspen Purple' acts as a herbaceous perennial, dying back to the ground after frost but re-emerging from its root system in spring. Over time, the plant can be divided and propagated to maintain vigor and produce new plants.

    • Propogation time

      Early Spring

    • Propogation: For the Lobelia × speciosa 'Hadspen Purple', also known as Hadspen Purple Cardinal Flower, the most popular method of propagation is through division. Early spring, just as new growth begins, is the ideal time for this process. To propagate by division, carefully dig up the parent plant, ensuring you keep a substantial amount of root with each division. Gently separate the clumps into smaller sections, making sure that each new section has a piece of the crown and several accompanying roots. These sections should then be immediately replanted in moist soil, spaced about 12 inches (approximately 30 centimeters) apart, to give each new plant enough room to grow. Regular watering will help establish the newly planted divisions. It is important to maintain consistently moist soil, especially during the first growing season, to ensure successful establishment of the divisions.
