In late 2002 our friend Rene Zahra from Malta received two little seedlings of Pierrebraunia brauniorum. One was grafted immediately, the other one grew on own roots.

Now, two years later, both plants have more or less the same size.
That shows the species seems to be easy in cultivation and grafting is not needed.
