Foamy bells × Heucherella tiarelloides

Water

Foamy Bells should be watered regularly to maintain a consistently moist soil, without allowing it to become waterlogged or letting the soil dry out completely. Typically, this plant requires an inch of water per week, either from rainfall or manual watering. If you need to supplement with manual watering, it's best to water deeply and less frequently to encourage root growth; this might mean providing approximately half a gallon to a gallon every week, depending on the climate and soil drainage.

Light

Foamy Bells thrive best in partial shade, where they receive some sunlight but are protected from the harshest midday rays. Ideal conditions are under the dappled light of trees or on the north or east side of a building where they will be shielded from the intense afternoon sun. However, they can tolerate some morning sun, which can help to bring out the colors in their leaves.

Temperature

Foamy Bells prefer a temperature range of between 60 and 80 degrees Fahrenheit for optimal growth. They can tolerate a minimum temperature of about 50 degrees Fahrenheit and a maximum around 90 degrees Fahrenheit but don't fare well in extreme heat or cold. Consistent temperatures within this range promote healthy foliage and vibrant colors in the plant.

Pruning

Pruning Foamy Bells is primarily done to remove any dead or damaged foliage and to enhance the plant's appearance, promoting healthier growth. The best time to prune is in early spring or after the plant has finished blooming. You should prune Foamy Bells once a year to maintain its shape and encourage new, vibrant growth.

Cleaning

As needed

Soil

Foamy Bells thrive best in rich, well-draining soil with a mixture of peat, compost, and perlite. Aim for a soil pH between 5.0 and 7.0 to ensure healthy growth.

Repotting

Foamy Bells should be repotted every 2-3 years to refresh the soil and to accommodate growth. Spring is the ideal time for this task.

Humidity & Misting

Foamy Bells prefer moderate humidity levels but are adaptable. Strive to maintain ambient humidity around 50% for optimal health.

Suitable locations

• Indoor

  Place Foamy Bells in bright, indirect light and ensure good air circulation.

• Outdoor

  Position Foamy Bells in partial shade with moist, well-drained soil.

• Hardiness zone

Life cycle

× Heucherella 'Stoplight' emerges in spring with fresh foliage, typically with a bright yellow to lime green color and distinctive red veining. The plant enters its vegetative growth phase, expanding its mounds of foliage and sending up stolons to spread. Flowering occurs in late spring to early summer, when × Heucherella 'Stoplight' produces small, airy flowers on slender stems that rise above the foliage. After pollination by insects, seeds may develop but are often sterile due to the hybrid nature of the plant. As summer progresses, the plant may enter a period of reduced growth, especially in hotter climates where partial shade and adequate moisture are necessary to prevent scorching. In autumn, the foliage often takes on additional hues before dying back, and the plant enters a period of dormancy through the winter months, surviving as a crown and root system until the cycle restarts in the subsequent spring.

  Spring to Summer

• × Heucherella tiarelloides, commonly known as Foamy Bells, is typically propagated by division. The best time to carry out this procedure is in spring or early fall when the plant is not in active bloom. Division involves carefully lifting the entire plant from the ground, using a sharp spade or knife to cut through the root ball, and separating it into smaller sections. Each section should have a good amount of roots and a few shoots. These divisions can then be replanted at the same depth they were growing previously, spaced about 12 to 18 inches (approximately 30 to 45 centimeters) apart to allow for adequate growth and air circulation. It's crucial to water the new divisions well after planting to help establish them.
