Those plants are from
Copenhagen Botanical Garden, growing outside at summer.
This member of the
Scrophulariaceae family was given
this name by Francis Whittier Pennell in 1947. It is found around 1000
meter height in Mexico, growing in a well drained soil with quite
some water in summer and next to nothing in winter. Plenty of sun,
and it will get lots of pink (rare form: white) flowers. The caudex
can grow to ten centimetres or more, the vines will reach for two to
as a member of the Plantaginaceae family.
