  • water dropWater

    The Round-leafed alumroot should be watered regularly to keep the soil evenly moist, but not waterlogged. It is best to water the plant deeply once a week, providing about one to one and a half gallons of water, depending on the size of the plant and the environmental conditions. During the hotter, drier periods, you might need to water it more frequently, while in cooler weather, you can reduce the watering schedule. Always check the top inch of the soil for dryness before watering again. Overwatering can lead to root rot, so ensure proper drainage.

  • sunLight

    The Round-leafed alumroot thrives in a location with partial shade to full shade. It should be protected from the intense afternoon sun, as this can scorch the leaves. The ideal spot for this plant would be under the dappled light of taller trees or on the north side of a building where it can receive bright, indirect light without being exposed to direct sunlight.

  • thermometerTemperature

    The Round-leafed alumroot grows best in temperatures ranging from 60 to 70 degrees Fahrenheit. It can survive minimum temperatures down to approximately 20 degrees Fahrenheit but should be protected from frost to prevent damage. During extreme cold, it's beneficial to provide some form of frost protection, such as a frost cloth.

  • scissorsPruning

    The Round-leafed alumroot benefits from pruning to remove old, faded leaves and to encourage a more compact, tidy growth habit. Pruning can be done in late winter or early spring before new growth begins. Deadheading the spent flower stalks after blooming can also promote a second flush of flowers.

    As needed

  • bambooSoil

    Roundleaf Alumroot thrives in a well-draining, fertile mix with a slightly acidic to neutral pH between 6.0 and 7.0. A combination of loamy garden soil, peat or coconut coir, and perlite or vermiculite can create an ideal environment for this plant. It is important to ensure the soil allows for good aeration while retaining adequate moisture.

  • plantRepotting

    Roundleaf Alumroot generally requires repotting every 2-3 years or when it outgrows its current pot. It is best repotted in the spring, just before the growing season begins. Always choose a pot that is slightly larger than the previous one to give the plant's roots enough room to grow.

  • water dropsHumidity & Misting

    Roundleaf Alumroot prefers moderate humidity levels but is quite adaptable to different environmental conditions. Ideal humidity for this plant ranges from 40% to 60%. If the indoor air is dry, especially during winter months, a humidifier or pebble tray with water can help maintain proper humidity.

  • circleLife cycle

    The life of Heuchera cylindrica 'Greenfinch', commonly known as the roundleaf alumroot or the Greenfinch coral bells, begins with seed germination, occurring in a moist and well-drained soil environment under partial shade. The seedlings emerge and develop into rosettes of basal leaves, which grow larger over time, with the foliage displaying a delicate range of greens and occasionally marbled patterns. As the plant matures, it sends up long, slender flowering stalks in late spring to early summer, topped with small bell-shaped flowers that attract pollinators. After pollination, seeds are produced, mature, and get dispersed, allowing for new plants to establish, creating a cycle of reproduction. In ideal conditions, Greenfinch coral bells maintain a perennial growth habit, with foliage persisting through the winter in milder climates, but may die back to the ground in colder regions, to re-emerge in spring. A mature Heuchera cylindrica 'Greenfinch' can also be propagated by division every few years to revitalize the plant and create new starts.

    • Propogation: Heuchera cylindrica 'Greenfinch', commonly referred to as the Greenfinch alumroot, is typically propagated by division. The best time to divide this plant is in the spring or early fall when temperatures are cooler, which reduces stress on the plant. To propagate by division, one should carefully dig up the plant and gently separate the clumps of crowns and roots, ensuring that each division has a portion of the root system along with several growing points or leaves. These divisions are then replanted at the same soil depth they were growing at previously, spaced about a foot (approximately 30 centimeters) apart to allow for growth and air circulation. Water the divisions well after planting to help establish them. This method is advantageous because it is simple and also rejuvenates older clumps that may have become woody and less vigorous. Dividing the plants can also help prevent overcrowding and promotes healthier growth.
