definitions given by Pat (and George Schmid) explain the terms. When it comes to
gold and partly gold hostas we see one of these phenomena. The tissue will
become more or less green as the season progresses. Some change dramatically,
and others only a little, but they all change color one way or the other. If the
conditions stay the same this should be a steady, gradual change. Other things,
especially sunlight, affect the color as well and must be taken into
account, but golds fall into one category or the other. It is my thinking that
lutescence is a sieboldiana/tokudama trait that does not come from any other
species. Most if not all species produce gold seedlings and all the ones I've
grown from other species were viridescent. When it comes to hybrids, I would say
that only hybrids with sieboldiana/tokudama in their parentage will show
lutescence. If both types result from a specific cross, the lutescent ones
usually outnumber the viridescent ones.
You can tell
very early which a seedling is by comparing the first or second leaves to the
later ones. If the new ones are brighter yellow, than it is viridescent. If the
newer ones are greener, it's lutescent. This becomes less obvious the more
fertilizer you use, as nitrogen makes them all get a lot greener.
found anything different to be the case?
Would any of you fine Ladies and
Gentlemen go into some detail in
explaining lutescence and viridescent
quality in leaf color.
