  • Genus: perfoliata 
  • Cultivar: ‘falcata’

How to grow propeller plant

Crassula falcata is a succulent plant with thick gray green leaves and bright red-orange flowers. It is very easy to grow and a succulent that does very well indoors.

Sunlight needs for crassula falcata 

Give propeller plant at least 3 hours of sunlight a day. 4-6 hours of indirect sunlight is ideal. Indoors, this means a south facing window.

The plant will require some partial shade if grown outdoors.

Watering requirements when growing a propeller plant

During the spring and early summer months, when the plant is actively growing, water this succulent regularly. Be careful not to overwater, since the plant is prone to decay if it receives too much water. 

Add additional water when the soil is dry to the touch.Propeller plant in a clay pot with a stone that reads dream.

Most succulents can take a bit of neglect in the watering department and still thrive. This makes them ideal for beginning gardeners who tend to forget to water a plant.

A good way to water is the “soak and drain” method.  To do this, bring the plant to the sink and give it a good soak, allowing the water to drain out of the drain hole in the bottom of the pot.

During the winter months, reduce the amount of water that you give the plant considerably, since the soil tends to retain moisture longer. Water only enough to keep it from shriveling.

Soil needs for propeller plant

Succulents have small root systems so small pots are often used. This makes the need for specially formulated soil a must.

Like all succulents, a well draining soil mix is needed for propeller plant since the plant is prone to root rot. 

You can choose a specially formulated soil for cacti and succulents, or add perlite and coarse sand to ordinary potting soil.

Top dressing items such as moss and rocks or pebbles add a nice look to the pot.

In general succulents like a slightly acidic soil with a pH about 6. 

How to fertilize crassula falcata 

Fertilize propeller plant with a cactus fertilizer or all purpose liquid fertilizer that is diluted to half strength. The best time to fertilize is during the active growing stage in late spring.

Fertilize once a month in the summer months.

Ideal temperature range for this succulent

Propeller plant  is happiest growing in warm temperatures above 64°F (17° C). During the winter months, it can survive temperatures down to 20°F (-6.7°C).

Flowers and foliage of propeller plant

Propeller plant produces flowers in the summer and fall months. The velvety gray-green leaves grow in a twisted pattern of opposite pairs, which are arranged in an overlapping pattern.Leaves of a propeller plant succulent.

The leaves also grow at slight angles, which creates the look of an airplane propeller.

The flowers start out as tiny buds in a large cluster and open to a spray of tiny red flowers. The scent is mild and reminiscent of cinnamon.Closed buds and open flowers of propeller plant.

The bright orange-red flowers of crassula falcata attract butterflies and bees. Flowers on indoor plants don’t grow as easily as those which have a summer outdoors.

To encourage flowering each year, try to avoid temperatures over 60° F during the winter.

Mature size of a propeller plant

Crassula falcata generally will grow 9 to 12 inches tall and 12 inches wide. Very mature specimens can reach two feet in size.

Larger plants tend to have stems that “flop over” the side of the pot. To discourage this, take stem cuttings to make the plant shorter and it will bush out to a better shape.Mature crassula falcata in a crock pot.

The plants are slow growing, so be patient with your propeller plant. However, they are also big plants and can get top-heavy and might need to be repotted regularly.

The plant looks good in a pot on its own or as a focal plant in a container with other succulents

Diseases and Insects that will bother crassula falcata

Like most succulents, fungal diseases caused from over-watering are something to be on the look out for. This could show itself with limp leaves that easily fall off.

Also look for rotting roots as a sign of fungal infection. Remove the rotting roots and treat the infection with a fungicide if you find any. 

Mealybugs, and spider mites are insects that can be a problem for propeller plant. Mealybugs show up as tiny white insects that have a cotton-like look to them.

Mealybugs can be removed with a Q Tip dipped in rubbing alcohol.

Spider mite infestation will be shown with tiny spider webs visible under the leaves.

Spider mite infestations occur in the dry season. They are very hard to get rid of if allowed to develop.

Remove any infected plants with mealybugs and spider mites to a separate location. These pests can easily spread to an entire succulent collection. 

Cold hardiness zones for propeller plant

Propeller plant will not winter outdoors unless you live in the hardiness zones 9 and above.

In colder climates, grow crassula falcata as an indoor plant. Also be sure to check out my list of cold hardy succulent plants.

How to propagate propeller plant

Get new plants for free by propagating propeller plants from stem or leaf cuttings, or by separating offsets that grow at the base of the plant. The plant is relatively easy to propagate.

To propagate crassula falcata from the leaves, twist the leaf gently to remove it from the stem of the plant.Leaves of a crassula falcata in a propagation tray.

Allow the leaf to callous over for 2-3 days. It will then be ready to plant.

Place the calloused over leaf on its side in well draining soil. In a few weeks, roots will attach the leaf to the soil. 

After a few more months, a new plant will form at the tip of the leaf.

Stem cuttings can be done the same way, except that you’ll use a whole section of stem which has calloused over.

The stem is then inserted into potting soil and will soon grow larger.

Leaf cuttings are a great way to get a lot of small plants for free. Stem cuttings will give you larger plants initially.

Propagating propeller plants from offsets

Crassula falcata sometimes self propagates by sending out offsets – small plants that are identical to the parent plant.

Cut the offsets away from the main plant with a sterilized knife. Allow the offsets to develop callouses for a few days.

Plant the offsets into well draining soil.

Toxicity of propeller plant

Some types of crassula (jade plant in particular) are toxic to pets. 

Crassula falcata is generally considered non toxic to humans and pets.

Note: Although this plant is considered non toxic, one should always take care growing plants around small children and pets.

Even though some plants are considered safe, children and animals like to chew on things within their reach. This might give mild affects once they are ingested.

Where to purchase propeller plants

Check the garden center of both Lowe’s and Home Depot. I found my plant at a small local garden center.

The Farmer’s Market is also a great place to purchase succulents. The plant is also available online:

Hi. I have an outdoor propeller plant, under 40% shade net, and it's growing 3 pups. The color of the pups are not green like the mother plant but are a yellowish color. Should I be concerned?

Sometimes the new pups vary a bit from the color of the mother plant. Usually not a concern.

I have propeller plants in my out door garden. The older leaves have turned yellow and are spotted with brown spots and the Stem looks very dry. Can you tell me what the problem is? I would appreciate it very much.

I can't diagnose any specific plant problems without seeing the plant in person. There are many things that could cause problems in plants, from too much sun, underwatering, pest infections and fungus can all cause this type of problem.
