Subject: Re: lutescence and
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.
