Gasteria plants are distinctive succulents, recognized for their varied foliage. While their thick, tongue-shaped leaves are a primary appeal, these plants also produce delicate flowers. This article explores Gasteria blooms and outlines conditions to encourage flowering.
Understanding Gasteria Flowers
Gasteria flowers have a unique tubular or “stomach-shaped” appearance, from which the genus name “Gasteria” originates (Greek “gaster” meaning stomach). These blooms typically emerge on a long, slender flower stalk, called an inflorescence. Individual flowers are often pendulous along this stalk. Their color commonly includes shades of orange, red, or pink, often with green or yellow tips. While shape and color vary by species, a common feature is a swollen base tapering towards the opening.
Encouraging Your Gasteria to Bloom
To encourage your Gasteria to produce its unique flowers, providing optimal growing conditions is important. Bright, indirect light is generally preferred; too little light can inhibit flowering, while excessive direct sunlight may scorch the leaves. Indoors, a south-facing window with filtered light or an east or west-facing window is often suitable.
Proper watering practices are also important for bloom induction. Allow the soil to dry out almost completely between thorough waterings during the growing season. Reduced watering is necessary during their winter dormancy to prevent root rot and encourage flowering.
A well-draining succulent or cactus potting mix, possibly amended with sand or perlite, provides necessary aeration. Gasteria thrive with warm summer temperatures and a cooler winter dormancy, ideally around 50°F (10°C), which can help trigger blooming.
Fertilization should be light and applied during the active growing season (spring and summer), using a balanced or low-nitrogen liquid fertilizer diluted to half strength. Gasteria plants generally need to reach maturity before flowering, which can take a few years.
Gasteria Flowering Cycle
Gasteria plants typically flower most prolifically during late winter, spring, or early summer. While exact timing varies by species and conditions, this period is when mature plants are most likely to produce flower stalks. Once a stalk emerges, it can last for several weeks to over a month, with individual flowers opening sequentially. A well-established Gasteria can flower annually under favorable conditions.
After Your Gasteria Flowers
Once your Gasteria has finished flowering, remove the spent inflorescence. Cut the flower stalk close to the plant’s base using clean, sharp shears. This practice, known as deadheading, conserves the plant’s energy. By removing the stalk, the plant redirects resources from seed production back into foliage growth. Continue with regular light and watering, allowing the plant to store energy for its next flowering cycle.
