Incarvillea delavayi, commonly known as the hardy gloxinia, is a perennial plant noted for its striking flowers and lush foliage. The leaves of this plant are pinnately divided, meaning they consist of a central stem with smaller leaflets arranged on either side. These leaflets are generally lance-shaped, with a pointed tip and a plush green hue that offers a verdant backdrop to the blossoms. The flowers of the hardy gloxinia are its most remarkable feature, large and showy with a trumpet-like form that beckons attention. These blooms are typically a deep pink to rose color, and may exhibit a yellow to white throat, which adds to the visual interest. The petals are velvety and often have a delicate, crepe-paper-like texture, while the stamens inside the flower tube contribute a subtle contrast. This plant displays a bushy growth habit, with multiple stems emerging from the base, each hosting clusters of the distinctive flowers. The hardy gloxinia's leafy stems and bright blooms combine to create an impactful display in gardens or as a featured plant in various settings. The overall appearance of the hardy gloxinia is one of lushness and color, making it a prized addition for its ornamental value.

  • water dropWater

    Hardy Gloxinia should be watered when the top inch of soil begins to feel dry, which typically means watering once every 7 to 10 days. Use a watering can to apply water slowly at the base of the plant, avoiding wetting the foliage, with about 1 gallon of water per plant during each watering session. In hotter, drier periods, increase watering frequency, but always allow the soil to dry slightly between waterings to prevent waterlogging. Avoid overwatering as it can lead to root rot, a common issue with these plants.

  • sunLight

    Hardy Gloxinia thrives in partial shade or an area that receives filtered sunlight. The ideal location would be a spot that is bright in the morning with some afternoon shade, or under the dappled light of taller trees or structures. Direct afternoon sunlight can be too intense and may scorch the leaves, so it's essential to find a balance of light and shade.

  • thermometerTemperature

    Hardy Gloxinia prefers temperatures between 60 and 75 degrees Fahrenheit, although it can survive brief periods of higher or lower temperatures. The plant is winter hardy in USDA zones 5 through 9, which means it can survive minimum temperatures down to -20 to -10 degrees Fahrenheit. For optimal growth, avoid exposing Hardy Gloxinia to temperatures below 50 degrees Fahrenheit for extended periods.

  • scissorsPruning

    Prune Hardy Gloxinia to remove spent flowers and dead leaves, which encourages new growth and blooms. This maintenance can be performed throughout the growing season as needed. The best time to conduct a more thorough pruning is in the late winter or early spring before new growth begins, cutting back any dead or damaged stems to maintain plant health and shape.

  • circleLife cycle

    Incarvillea delavayi, commonly known as the hardy gloxinia, begins its life cycle when its seeds are sown in well-drained soil after the threat of frost has passed. Germination occurs over a period of several weeks, and seedlings emerge with elongated, pinnate leaves. As the plant matures, it develops a rosette of foliage at the base and sends up flowering stems in late spring or early summer, which showcase trumpet-shaped flowers in shades of pink or white. After pollination, usually by bees or other insects, the flowers produce elongated seed pods that eventually dry and split open to release seeds. The hardy gloxinia is a perennial species, so it will die back to the ground in the autumn, entering a dormant phase over the winter. With the return of warmer weather in spring, the plant will regrow from its tuberous roots, continuing its life cycle.

  • sproutPropogation

    • Propogation time


    • Propogation: For hardy gloxinia, the most popular method of propagation is by seed. The optimal time for sowing hardy gloxinia seeds is in the spring when the risk of frost has passed. To propagate, seeds should be scattered on the surface of a well-drained seed starting mix, lightly covered with soil, and kept moist but not waterlogged. A temperature range between 60 to 70 degrees Fahrenheit (15.6 to 21.1 degrees Celsius) is typically considered ideal for germination. Under proper conditions, germination can be expected within two to three weeks. Once seedlings have grown large enough to handle, they can be transplanted into individual pots or spaced out in the garden to grow to maturity.
