Watering

Drought tolerant; water sparingly, only after the mix dries, and even less in cool weather.

Temperature & Overwintering

It does not tolerate freezing. A US grower reports it surviving around -6°C, but potted plants should come into a frost-free room or greenhouse in winter.

Soil & Repotting

Plant in a loose, well-aerated mix. Tall plants become top-heavy, so choose a stable pot.

Pests & Cautions

The summer flowers last nearly a month. It may also be labelled with the older name Crassula falcata or as var. minor.

7 things to know before growing Propeller plant

1. 1Light and airflow

   Give it a sunny, well-ventilated spot. Too little light stretches the stems and loosens the stacked leaves, so the propeller-like shape is lost. Indoors, choose a bright windowsill.

2. 2Water when dry

   Let the soil dry out, then water thoroughly until it drains from the bottom of the pot. The thick leaves store moisture, so constantly damp soil invites root rot. Cut back sharply in winter and keep the plant on the dry side.

3. 3Fast-draining mix

   Use a commercial succulent and cactus mix, or blend extra akadama or pumice into regular potting soil for good drainage. As the plant grows taller it becomes top-heavy, so a stable pot helps prevent tipping. Always choose a pot with drainage holes.

4. 4Repotting and pruning

   Repot in spring or autumn, roughly once every one to two years, when the roots fill the pot. If the stems stretch and lose their shape, cut them back to tidy the plant. Let the cut ends dry, and the trimmed stems can be used as cuttings.

5. 5Summer heat, winter frost

   In midsummer, intense direct sun and stuffy heat can damage the leaves, so move the plant to bright shade with good airflow. Water sparingly during hot weather. In winter, bring it under eaves or indoors before frost arrives.

6. 6Enjoying summer flowers

   Dense heads of small scarlet flowers open at the stem tips in summer. To enjoy them, give the plant plenty of sun all year so it builds up strength. Snip off spent flowers to keep it tidy.

7. 7Choosing a plant

   Look for firm, gray-green leaves stacked neatly and alternately left and right. A compact plant with steady, unstretched stems is easier to grow. Check the photos and description for wrinkled or discolored leaves and a blackened stem base.

A.Yes, it is rated beginner-friendly. Give it bright light and good airflow, use a fast-draining mix, and water only after the soil has dried out. As long as you avoid overwatering, it is relatively easy to grow.

Q.How large does the propeller plant get?

A.It is a perennial that reaches 60 cm to 1 m in height. As the stems lengthen the plant can become top-heavy, so a stable pot is a good idea. If it loses its shape, you can cut it back to tidy it up.

Q.When does the propeller plant bloom?

Q.Can I grow it indoors?

A.Yes, if you can give it a bright spot such as a sunny windowsill. Too little light makes the stems stretch and the stacked leaves loosen, so it helps to set the plant outside in good light on fine days. Keep the air moving around it as well.

Q.How do I propagate it?

A.Stem cuttings are the usual method. Let the cut end dry for a few days, then insert it into a fast-draining mix and keep it in bright shade. Avoid overwatering until the cutting has rooted.
