Summary
Soft, trailing foliage paired with an unusually long bloom season makes ‘Concord Blue’ a standout choice for bright indoor spaces and sheltered patios.
Streptocarpella saxorum ‘Concord Blue’ produces graceful sprays of rich blue-violet flowers that rise just above its velvety evergreen leaves. Once mature, plants flower repeatedly through much of the year, creating consistent color without demanding care.
Its naturally cascading habit makes it especially well suited to hanging baskets, elevated planters, and plant stands where the foliage and flowers can spill gently over the edges. In warm climates, it can also be grown outdoors year-round in protected locations.
Care
False African Violet Care
Provide bright, indirect light or filtered sun for best flowering and compact growth. Too little light may reduce blooming, while harsh direct sun can cause leaf stress.
Use a well-draining potting mix and keep soil evenly moist but never saturated. Allow the top layer of soil to dry slightly between waterings.
This plant appreciates moderate humidity and performs well indoors with normal household conditions. Additional humidity may be beneficial in very dry environments.
Fertilization is optional but helpful during active growth. A light application of slow release fertilizer in spring supports steady growth and flowering.
