Introduction to the 19 species and 6 cultivars of Boswellia.

 

Like me, most of you probably have not heard of Boswellia. They are related to Bursera, which you may well have heard of or grow already. They come from tropical Africa, the Arabian Peninsula and India, and seven of the species are endemic to the island of Socotra. They are best known for the gum resin frankinsense that is extracted, mainly from Boswellia sacra. It has been used as a medicinal and beauty product and was prized for its aromatic incense from ancient times, having a long association with religious ceremonies.

From the horticultural point of view they make very attractive bonsai subjects, but are not very succulent and require more warmth than most growers can financially justify. This also restricts the availability, so only a few species are usually available from specialist nurseries.

This book tells you more or less everything you will ever need to know about boswellias, and the author gives generously of his cultivation experience. The requirements are similar to those for succulents generally, and the author stresses a low pH, well-drained but moisture-retentive compost. They can withstand drought for a few weeks, but drop their leaves in response to it, and it will check the growth. They are better grown continuously with the compost never completely drying out. In pots, daily or even more frequent watering is recommended for plants in full growth.

Flowering and pollination are strongly influenced by air humidity, and the author offers the interesting idea that the plants are sensitive to atmospheric pressure, quoting results from NASA experiments. Propagation is from seed or stem or root cuttings, and 25-32ºC is needed for success.

Even if you never grow boswellias, you might well still consider buying this book for its cultivation advice and hints on such subjects as showing, which are applicable to the management of a wide range of tropical bonsai succulents.
