Etymology
The specific epithet "grandiflora (pronounced gran-dih-FLOR-uh)" means "having large flowers" and refers to the large, showy flowers of this species.
Origin
Kalanchoe grandiflora is native to India. It grows on slopes and rocky ground with poor soil at elevations ranging from 3,280 to 6,560 feet (1,000 to 2,000 m).
Description
Kalanchoe grandiflora is a succulent plant with erect, branched stems bearing bluish-green to blue-violet leaves with an easily removed waxy coating. It can grow up to 3.3 feet (1 m) tall. The leaves are fleshy, usually inversely egg-shaped, and have margins with small rounded teeth. They can measure up to 3 inches (7.5 cm) long and 1.4 inches (3.5 cm) wide.
The fragrant flowers are yellow to greenish-yellow and appear in terminal, many-flowered clusters in late spring and summer. The corolla tube is 4-angled, bottle-shaped, and can reach up to 0.6 inches (1.5 cm) in length. The fruits are 4-angled follicles that contain many tiny seeds.
How to Grow and Care for Kalanchoe grandiflora
Light: K. grandiflora grows best in full sun but usually appreciates some part shade in the heat of the day. Indoors, place your plant near a window that receives indirect sunlight. It will stretch if it does not have enough light.
Soil: Like most succulents, K. grandiflora does not like "wet feet" and needs well-draining soil. Commercial potting mixes for succulent plants will work fine.
Temperature: This plant thrives in heat and humidity but is intolerant to frost. K. grandiflora can withstand temperatures as low as 30 °F (-1.1 °C). USDA Plant Hardiness Zones 10a to 11b, 30 to 50 °F (-1.1 to 10 °C).
Watering: Water thoroughly from spring to fall, but let the soil dry between waterings, as overwatering may cause stem rot. Reduce watering during the winter months. Water your plant just enough to prevent the leaves from shriveling.
Fertilizing: K. grandiflora benefits from occasional fertilizing during the growing season. Use a balanced fertilizer diluted to half or quarter strength applied every two weeks.
Repotting: This plant thrives better when frequently repotted, as this encourages new growth and health. For optimum growth, repot them every two years in spring. Go up one pot size every time you repot.
Propagation: Propagate by seeds, offsets, or leaf and stem cuttings. Spring is the best time to take leaf cuttings and separate offsets. Sow the seeds in spring or summer.
