Gently cut the rooted stem from the host and plant in free-draining and moisture- retaining substrates such as a mix of perlite and peat-based soil. Place in a shaded area to gradually acclimatise. The following Tacsonia species have been successfully rooted using this technique. • P. manicata • P. tripartita var. mollissima • P. mathewsii • P. parritae • P. cumbalensis • P. mixta • P. antioquiensis It is quite possible that other less common Tacsonia species may be propagated with this technique, but they are difficult to find in Japan.

It has been named as P. ‘Scorpius’ Eliott’ (♀) × P. loefgrenii ‘Iporanga’ (♂); Figure 1) (Figure 2). Meanwhile, the reciprocal cross (P. caerulea × P. was created by Maurizio Vecchia; it first flowered ‘Lunametista’) has yet to flower. in 2005. P There are now many hybrids based on crosses between P. caerulea and either of the two forms of P. loefgrenii (see In 2009, I crossed P. ‘Lunametista’ with P. caerulea. Table 1). I have grown P. ‘Lunametista’, P. ‘Lambiekins’ Unusually, the pollen of P. ‘Lunametista’ proved to be and P. ‘Betty Myles Young’ for several years, but none has fertile, and I was able to create viable offspring from both proven hardy enough to survive winters outside at my crossing directions. However, it was not until late summer location. My objective in creating yet another hybrid with 2012 that the hybrid P. ‘Lunametista’ × P. caerulea this parentage was therefore to produce a tougher plant. 14.
