foam flower 'Mystic Mist'


The Tiarella 'Mystic Mist', also known as foamflower, is a charming perennial plant known for its decorative foliage and delicate flowers. The leaves of the 'Mystic Mist' are heart-shaped with a unique patterning; they are green, often with deep maroon markings following the veins, and boast a frosted appearance as if dusted with white paint, which contributes to the 'misty' effect that gives this plant its name. In spring to early summer, the foamflower produces slender, upright stems topped with feathery plumes of tiny star-shaped flowers. These blooms are usually a soft pink or white color, adding a light, airy touch to the delicate display. The plant has a mounding and clumping habit, creating a lush, textured effect in garden beds and borders. The combination of the decorative leaves and whimsical flowers of the foamflower makes it a favorite among gardeners looking to add both foliage interest and flowering beauty to their shade gardens.

As needed
  • water dropWater

    Foamflowers should be watered regularly, aiming for moist but not waterlogged soil conditions. Typically, you should give them about 1 inch of water per week, which could equate to around 0.6 gallons per square yard of soil. During hot, dry spells, water the plants twice weekly to maintain moisture levels. Always water the base of the plant, avoiding overhead watering to minimize the risk of leaf diseases. Ensure proper drainage as Foamflowers do not tolerate standing water well.

  • sunLight

    Foamflowers thrive in partial to full shade, making them well-suited for woodland gardens or areas under the canopy of larger trees. They perform best in dappled sunlight, which replicates their natural understory habitat. Avoid placing them in full sun, as this can stress the plants and lead to scorched foliage.

  • thermometerTemperature

    Foamflowers prefer cool to moderate temperatures and can survive a range of conditions from USDA hardiness zones 4 to 9. They are hardy in temperatures as low as -30°F and as high as 85°F but grow best when the temperature is consistently between 60°F and 70°F. Protect them from extreme heat which can cause stress and wilting.

  • scissorsPruning

    Pruning Foamflowers is usually done to remove dead or damaged leaves and to encourage a tidy appearance. Lightly trim the plants after flowering to maintain shape and remove any spent flower stalks. The best time to prune is in the spring or immediately after flowering to ensure vigorous growth and a neat mounding habit for the following season.

  • circleLife cycle

    Tiarella 'Mystic Mist', commonly known as Foamflower, begins its life as a seed that germinates in moist, well-drained soil, ideally in partial to full shade. After germination, a rosette of green leaves with a characteristic white patterning develops, and the plant focuses on vegetative growth. As the plant matures, it develops a clumping form with heart-shaped leaves and in spring, it sends up slender, erect flower stalks crowned with delicate, foamy white or pale pink blooms. After flowering, seed pods form and disperse seeds for reproduction, although Foamflower can also spread vegetatively by stolons, forming a ground-covering mat. Post-flowering, the leaves often persist, providing ground cover and winter interest, as this plant is an evergreen to semi-evergreen perennial. Throughout its life, the Tiarella 'Mystic Mist' requires consistent moisture and will die back to the crown during the dormant winter period, only to regrow from the same root system the following spring.

      Spring-Early Summer

    • Tiarella 'Mystic Mist', commonly known as foamflower, is typically propagated in the spring or early summer. The most popular method for propagating this perennial plant is by division. Division involves carefully separating the densely packed clumps of the plant into smaller sections, each with several shoots and a healthy root system. These sections are then replanted directly into the garden or into pots filled with a well-draining potting mix. It is important to keep the newly transplanted divisions well-watered and shaded from intense midday sun until they are established. This method of propagation is straightforward and helps to rejuvenate older plants that may have become too large or are beginning to decline in vigor.
