The flowers are tubular with five lobes and are densely clustered at the tips of the stems. The petals are blue-violet with a white throat, and the stamens are colored yellow. The flowering period is from November to April.Light Requirements
The Callistigma inachabense requires bright but indirect light to thrive. It should be placed in a spot where it can receive ample sunlight for a few hours each day but must not be exposed to direct sunlight. Too much exposure to sunlight may cause damage to the leaves and hinder growth.
Temperature Requirements
The Callistigma inachabense plant can grow in moderate temperatures ranging from 15°C to 25°C. It is important to avoid extremely low temperatures, as they can cause the leaves to wilt and die. In cooler temperatures, the plant may also go dormant, halting growth. On the other hand, exposing the plant to high temperatures may cause the leaves to dry out and fall off.
Soil Requirements
The Callistigma inachabense plant requires well-drained soil that is rich in nutrients and organic matter. It thrives in acidic to neutral soil with a pH range of 6.0 to 7.5. The soil should also have good aeration and be loose enough, allowing the water to penetrate deep into the roots. Regular fertilization using a balanced fertilizer is recommended to keep the plant healthy and promote growth.
Cultivation of Callistigma inachabense
Callistigma inachabense is a flowering plant that thrives well in warm tropical regions. It is also suitable for indoor and outdoor cultivation in containers and gardens.
Watering Needs
Callistigma inachabense requires moderate watering. Avoid over-watering or letting the soil dry out completely. Water the plant only when the top inch of the soil is dry. The plant prefers well-draining soil to avoid waterlogging that can lead to root rot.
Fertilization
Feed Callistigma inachabense using a balanced liquid fertilizer every two weeks during the growing season. Reduce fertilizer application during the dormant season to once a month. Avoid fertilizing the plant during winter.
Pruning
Prune Callistigma inachabense regularly to maintain its shape and size. Cut off any yellow or damaged leaves to encourage new growth. Pinch off any unwanted flower buds to encourage the plant to put more energy into growing foliage.
Propagation of Callistigma inachabense
Callistigma inachabense (Engl.) Dinter & Schwantes is propagated through various methods. The plant can be propagated through seeds, cuttings, and division.
Propagation through seeds
Callistigma inachabense can be propagated through seed by sowing it at the beginning of the growing season. The seeds should be sown in well-draining soil and kept moist. Germination can take up to 3 to 4 weeks.
Propagation through cuttings
The plant's cutting can be taken in the growing season. The cutting should be 5 to 6 inches long and should have a few leaves. The cutting should be dipped in rooting hormone powder and planted in well-draining soil. The soil should be kept moist until the cutting roots, which can take up to 4 weeks.
Propagation through division
Callistigma inachabense can also be propagated through division. The plant should be dug up carefully and divided into smaller sections. Each section should have 2 to 3 stems and a few roots. These sections can be planted in well-draining soil and kept moist until they establish.
