Re: Curves of Beauty

Interesting topic..Now you have me thinking too.

As a personal measure for comparing your hostas (or even judging how one cv
 behaves under particular environmental conditions) this seems like a
valuable tool. But I see two problems with its general use.

1) As Diane points out, this is a highly subjective measure as described.
if your index was comprised of more objective measures (e.g., degree of
leaf burn, rated on a scale of 1-3, or % of original leaves remaining, and
so forth) it would be possible to compare the same cv in different gardens
in defferent years. But what I consider beautiful or desirable in a hosta
might be different than what you do, even if we were standing side by side
and rating the same plant. I might, for example, like how Vanilla Cream
changes color throughout the season while others might see it as fading or
"viridescing" (is that a verb?) and rate it downward.

2) The other problem relates to Joanne's suggestion that the area under the
curve be calculated and used for comparison. But what descriminates between
two hostas is the *shape* of the curve, not the area under it. Both can be
mathematically described. Your two hostas, one peaking early and one
peaking late, might have the same area under the curve; does that make them
equally beautiful (or valuable in the garden)?

My $0.02 worth..

Come on, guys! Don't give yourself ulcers over the AHS Robin, it's not
worth it. This kind of discussion is what hosta-open is for. Let's discuss!
