ISI 2026-25. Peperomia 'Cactusville' G. Rowley.
Many of the more succulent species of Peperomia are native to Peru. These have very succulent leaves that exhibit fascinating examples of the "windowed" adaptation. These look as if a typical flat leaf blade has been folded in half and the resulting channel has been filled in with translucent, succulent tissue. This translucent window acts as a skylight, allowing light to reach the inner photosynthetic layer which is protected from water loss by being embedded in this succulent tissue. Peperomia asperula Hutchison & Rauh is one of the more commonly grown succulent species, and, like many peperomias, bears slender green spikes with minute, self-fertile flowers. Peperomia 'Cactusville' appears to be a selfed seedling or hybrid of P. asperula (or P. nivalis Miq.) and was selected by Gordon Rowley when it appeared in his greenhouse in Reading, England. It is customary in England to give one's estate, however modest, a name that reflects the character of its master. In Gordon's case, he gave it the whimsical name "Cactusville" reflecting his nearly life-long interest and study of succulent plants. Hence, that name was applied to this Peperomia that originated there. We recently planted some out in the upper Desert Garden in a shaded rockery where it has thrived, becoming a tight, rich green cushion that invites the curious to peer into its windows. Rooted cuts of HBG 129007, a plant from Myron Kimnach in 2014 who received it from Gordon and had it labeled "G. Rowley hybrid selection 4/97."
