Spath Nursery also grew 'Prinz Hanjery' and the yellow one probably belongs ns, id: there. eval: it is best regarded as one of the better clones of f. purpureum and worth keeping pure.

Not all years are as bright as others. geo: Bavarian Alps, known in the wild ns, id: many of the purple-backed clones from f. purpureum have red fruits or at least ns, id: red in the wing portion even if the rib and seed are green. Some WINELEAF PLANES ns, id: are more red-fruited than others. Traditionally this name is reserved for green-backed ns, id: plants with very red schizocarps. In the wide sense, this forma represents any plant with ns, id; any red-fruited genes. The most important lesson in modern times, as that a specific ns, id: good clone of valuable fixed traits should be cloned, well described, and named something ns, id: new. in: France nursery trade c. 1864. Some say it was first introduced by S. Vaillant, France as in: early as 1727. Doubtless it may have had several introductions over the years.
