Boswellia nana
Boswellia nana is a dwarf member of the frankincense genus Boswellia, found clinging to limestone cliffs on Yemen's Socotra Island. Its rounded, bottle-shaped base sends out short branches, and unlike other Boswellia species, it produces pink to crimson flowers, its signature feature. Adapted to a harsh, arid, rocky habitat, it suits caudex-style cultivation that highlights the swollen base over time. Growth is slow, gradually forming a distinctive silhouette, making this a plant best suited to experienced growers.

- Growing Difficulty
- Advanced
- Lifespan
- Long-lived woody perennial (little published data)
- Size
- About 60 cm tall in habitat (hanging 60-100 cm on cliffs); can exceed 1 m in cultivation
- Watering
- Liquid fertiliser about monthly in spring and summer
- Light & Placement
- It likes plenty of light and fresh air. In summer, moving it outdoors to sun or partial shade keeps growth compact.
- Watering
- Increase water during growth and flowering. It drops leaves if overwatered, so give about as much as other succulents.
- Temperature & Overwintering
- In winter keep it bright with a minimum of 12-15°C. If kept warm do not let it dry out completely; if kept cool, reduce water and let it rest.
- Soil & Repotting
- Root-prune and repot every two years after the winter rest. It tolerates being somewhat pot-bound.
- Pruning & Shaping
- The shape comes from the thick base and a few short branches, so heavy pruning is unnecessary; keep cuts to a minimum.
- Pests & Cautions
- Known from only two wild sites, it is critically endangered. Choosing plants raised from seed in cultivation rather than anything of wild Socotran origin helps its conservation.

7 things to know before growing Boswellia nana
1Placement & Sunlight
Boswellia nana thrives with strong light and good airflow, much like its native cliffside habitat. Indoors, place it as close to direct sun as possible — a shaded windowsill will leave the base looser and less compact.
2Watering
This plant is adapted to dry, rocky terrain, so overwatering is the main cause of root rot. Water thoroughly once the soil has dried out during the growing season, and cut back further when growth slows.
3Choosing the Right Soil
A soil that retains too much moisture invites root rot, so use a fast-draining mix heavy in akadama, pumice, or similar mineral components. A coarse drainage layer at the bottom of the pot also helps prevent water from pooling.
4When to Repot
The roots are sensitive, so repot only once temperatures have stabilized and the plant is actively growing. Avoid disturbing the root ball more than necessary — trim only damaged roots and move up to a pot roughly the same size or slightly larger.
5Winter Care
Boswellia nana is sensitive to cold, so move it to a warm, bright indoor spot as temperatures drop. Growth slows and water uptake decreases during cooler months, so water even less frequently and let the soil stay on the dry side.
6Choosing by Base Shape
The appeal of Boswellia nana lies in its rounded, bottle-shaped base. When choosing a plant, look for a firm, unblemished base without excessive wrinkling, a good sign for healthy future growth.
7Patience Pays Off
Growth is slow, and it can take years before the distinctive silhouette really develops. This plant suits growers who enjoy watching a caudex change gradually rather than expecting fast results.
