Nenella, C. percivaliana plants are a bit like a lottery. Some of them can be quite stinky, others just smell like mushrooms... some smell like dirty socks, others like camenbert or stink bugs... However, the gragrance is never too strong that it can contrares the beauty of these plants blooming for Christmas time
...and they are quite easy Catts too
you will probably find that the best this species can offer is C. percivaliana 'Summit' HCC/AOS (indeed a great plant), however there are many other very interesting clones. especially alba, albescens and semi-albas: e.g. 'Caracas', 'Jewel' and 'Carache'
