foam flower

Foam flowers (Tiarella 'Black Velvet') prefer moist, but not wet, soil. Water them when the soil dries to a depth of 2 inches. During spring and summer, water foam flowers once per week. During fall and winter, water when the soil has been dry for 2 or 3 weeks. It is best to use a soaker hose for these plants, as overhead watering may cause fungal diseases.

Foam flower (Tiarella 'Black Velvet') prefers a location with part to full shade and doesn't require more than 4-6 hours of direct sunlight per day. In areas with long summer days, it's best to give it some afternoon shade. Uneven and bright light can cause leaf scorch, so be sure to check if the foliage looks discolored and adjust the sunlight exposure as needed. In zones 6 and colder, this plant enjoys full sun, while in zones warmer than 7, it prefers partial shade.

Foam flower (Tiarella 'Black Velvet') should be pruned in late spring, once the danger of frost has passed. Trace back each stem until you reach the crown of the plant, then cut off the top 1-third of the stem. This measure will encourage a denser growth habit, which is ideal for this variety of foam flower. Additionally, you can remove any dead stems or foliage that appears during the growing season.
