    Dear Jason,

    Thank you so much for publishing your new book! I have read it cover to cover and have learned ever so much! I can certainly recommend this book unconditionally to anyone interested at all in learning about or cultivating these marvelous species!

    I understand that you are writing two other volumes on the Burseraceae: Bursera and Commiphora, to complete a 3-volume series on this family of plants. I eagerly await them!

    Hey Jason and Patte 🙂

    Great book Jason, the info on each specie and genus in general is pretty darn thorough. It has given me more confidence in growing these guys. It has also saved me money on collecting certain species that our climate can not mimick (unless I get a greenhouse goin, then the obsession will really begin).

    I am curious if you have begun an F2 hybrid on crossing an F1 with sacra parentage back to a sacra to see if you can get a plant that highly resembles the sacra but with greater germination results?

  3. admin Says:

    Thanks for the kind words. Yes, I have already started f2 and f3 process for two of the hybrids and the results are very promising. I am presently collecting F3 seeds from Boswellia sp. shealynn and I believe they will produce true self from this point on.

    Very good! This excites me, can’t wait to see em. Tried a tiny root cutting today of a sacra when I bumped it’s pot up, hope all goes well. The dioscoridis cutting I had to do is leafing out as well, I found using 2-3″ pot with vermiculite worked pretty good in rooting it… to control excess moisture I just quickly dunk the bottom 1/4 of the pot in a solution of water and captan.

    Think you can start a topic on here for bursera and commiphora as well?

    Dear Jason, perhaps you can clear up some confusion for me. The International Plant Name Index (IPNI) website lists 41 species for the genus Boswellia, and The Plant List lists 30 “accepted” species for the genus, and your book says there are 19 true species—why should there be such a discrepancy in the number of species? Thanks!

    Dear Jadefaerietriste, Your question was one of the many reasons that I wrote the book in the first place. The two sites that you mention (IPNI & the Plant List) have simply listed all the Boswellias described at one point or another, with no consolidation of the synonymous names, or plants previously described as Boswellias but no longer in the Boswellia genus. For example, Boswellia madagascarensis (Ambilobea) and Boswellia bricchettii (Lannea obovata) are no longer Boswellias. Others, like Boswellia carteri and Boswellia hildebrandtii have been recognized to be synonymous as B. sacra and B. neglecta respectively. In the final analysis, if one eliminates the false Boswellias and the synonymous names, one will arrive at 19 true species in the genus. The book has listed all the synonymous names of each species under the heading Synonyms in the species section.

    Dear Jason, dear Patte,

    this book is absolutely fantastic. As I am a non-professional grower of the Burseraceae-family, it is a priceless guide to propagation of this extraordenary plant family. I can’t wait to see the volumes about Commiphora and Bursera. Do you have an idea, when these books are going to be published? All the best!

    Jason, i do not have a greenhouse as you know, my boswellia’s are grown outdoors, currently have them under the elm tree where they get the morning sun and their pots are shaded from direct sun. I am noticing on the nana that leaves are sparse, and some of the older leaves are dry/crispy from half the leaf to the tip, the upper smaller leaves have not developed this trend yet, but am assuming it will. The ameero has not budged an inch with our warmer temps yet, and the sacra leaves have for the most part started going crispy, some of the leaf structure too has fallen away from the main stem. The neglecta has started to form bud, but has been sitting limbo in its “bud swelling stage” for weeeeeks! After reading your book, is it safe to assume it is the 20% humidity we have been having that is causing this? I have made sure to not let the soil dry out at all, and to make sure i am not watering so much as to make the soil “soggy”. I also water very thoroughly when i do water to leach excess salts. These symptoms remind me of salt burn and just plain old dry air. I hope i am correct in assuming this.

    It takes three conditions for these plants to bud out or form buds in anticipation for a more favarable condition; heat, low barometric pressure and humidity. The last couple of weeks we had all three conditions. My plants are doing the same and most are flowering. In fact Boswellia sp. shealynn is covered with efflorescence.
    Regarding the leaf condition, it is due to the cold temperature and the dry winter that we just had. If new leaves manifest the same conditions, send me some photos and lets discuss it further. I think you are doing all the right things but need to get used to the unpredictability of growing these plants outside. These plants are reactionary to variable environmental condition and will often show stress in one day and a burst of growth in another day.

    forgot to mention, my Commiphora sp. ‘Puntland’ i believe, at least it is what it resembles, is verrrrry slow to want to do anything, behaving like my B. neglecta.

  11. Anthony Says:

    That puts me to ease Jason, thank you! My ameero decided it didn’t like it’s leaves and decided to shed them… such is life 🙂 Im sure it really loved our humidity of 2% not too long ago… Monsoon season is not too far off and I can not wait to see these guys react!

    Dear Jason,

    I’ve been waiting a long time for a printed edition like this and I couldn’t await reading your book. Originally I was interested in learning more about these plants and their habitat because of my diploma thesis that concerns the Boswellia serrata plant and it’s inflammantory effects.
    But after reading all these information you provided I’m very eager now to cultivate them, too; I have to admit that I’m hooked :-).
    I very appreciate your book, it’s already one of my favourites! Not only it is written very detailed and cleary (for a beginner like me) about these very special plants, but includes as well beautiful and stunning pictures. I love that you gave these plants the chance of being more known with your really fantastic book.

    Thank you,

    Dear Folks,

    Together you have really brought Boswellia out of the abstruse textbooks and into our hearts (and homes!). The horticultural work you have done over decades growing pretty much ALL the Boswellias is really invaluable, as you have a broad knowledge across their behavioral spectrum. Not to mention the opportunity you have seized to make appealing hybrids of B. sacra to improve its seed viability (amongst other things…).

    I second the suggestion above from Anthoy to BACK-cross some of the F1 hybrids like “Tierney” with B.sacra again to see if you can end up with a plant that is MOSTLY B.sacra, with just a crucial admixture of (say) B.popoviana

    Long may your good work continue!
