Crassula Falcata

Crassula falcata is a very distinctive-looking succulent that has overlapping pairs of greyish-green colored, sickle-shaped leaves that radiate outward and give it the appearance of propellers. This is the reason Crassula falcate is also called Propeller Plant or Airplane Plant.

The succulent is also given the name Scarlet Paintbrush because it produces a dense cluster of beautiful flowers in the summer or fall season. The flowers are colored bright orange-red or sometimes scarlet-red, measure 3.14-inches to 4.72-inches wide (8cm to 12cm), and gives off a mild, almost indiscernible scent.

Crassula falcate can grow up to 12-inches to 24-inches (30.5cm to 61cm) tall and 12-inches (30.5cm) wide. It is part of the Crassulaceae family and is native to South Africa. 

How to Grow and Care for Crassula Falcata

Crassula Falcata is a very easy succulent to plant and grow. It is not a cold-hardy plant. If you live in a region where the temperature can drop below 20° F ( -6.7° C), it would be a good idea to place Propeller Plant in a container and brought indoors. 

1.   Sunlight

Crassula falcata needs 3 hours of sunlight per day in order to thrive. When grown indoors, place Propeller Plant near a window that receives sunlight. If you want to move the succulent to the outdoors in the summer, do a gradual exposure to the sun.

Start out by placing Crassula falcate under a lightly-shaded area then slowly expose the plant to the sun for a few hours at a time. If exposed to the sun right away, the plant can get scorched.

2.   Watering

Crassula falcata should have a regular watering schedule during the summer. Propeller Plant is susceptible to the dangers of overwatering. It is recommended to give Crassula falcata water only when the soil is dry to the touch.

During winter, the soil tends to retain moisture longer. The watering schedule for Crassula falcata must be greatly reduced.

When the succulent is in its active growth stage which is around the 4th to 8th week, feed it with standard liquid fertilizer or cacti fertilizer that is diluted with water to lower its potency.

3.   Pot and Soil

Crassula falcata is best planted in a pot that has good drainage to prevent moisture from building up. Cactus soil or a regular potting soil mix combined with pumice and bird sand will drain it of excess moisture.

It is recommended to re-pot Crassula falcata during spring when the succulent has outgrown its pot. Make sure the soil is dry before re-potting. Gently remove the pot and shake away excess soil from the roots of Propeller Plant.

Look for rotting roots and signs of fungal infection. Remove the rotting roots and treat the infection with a fungicide.
