Hi Steve,
I'm not quite following you even though you clarified your
statement... The seeds from which cv. 'Royal Red' grew, *were
wild collected*. So then, would the S. purpurea subsp. purpurea
(all-green), occurring naturally in northern sites, be welcome in
your collection? Just not plants like S.purpurea subsp. venosa
(all-green) which were grown from wild collected seed but then
propagated by the grower?
I'm a purist and that's why I see the var. heterophylla as a
very asinine designation for the northern S. purpurea (all-green)
plants.
