Hi Angela, Gary & All,
What tribulations ? My first attempt did not go well because I had to =
learn how to do it effectively. Don't take my word for any of this. Try =
it yourself.=20
=20
Mark >100 blossoms in each of several years and see how many set =
and whether those that do set are unusually vigorous. Note how many =
plants got nipped off by deer as they emerged and how many blossoms get =
nipped high later. Hand-pollinate five and see how many of these set.
The Sand County Almanac: "We grieve only for what we know." bears on =
the 'look but don't touch' school of thought. And on the flip side, =
conservation should be based on sound information, not on dogmatic =
prejudice-based assertions such as "it is unethical" to pick Common =
Lady's Slipper flowers.

Thanks for your reply Dave. I do remember reading your trials and =
tribulations regarding hand pollination of the lady slippers.=20

Hi Angela & All, Apr 28, 2013
It was (and perhaps still is) illegal to pick Common =
Lady's Slipper (Cypripedium acaule) in parts of New England but the =
prohibition has no sound biological basis.=20
Under our conditions and in typical years only the most =
vigorous blossoms (roughly 1% of total blooms) will set fruit by natural =
pollination by Bees. But if hand pollinated at the right time (as I have =
described on NatureNS) nearly 100% of hand pollinated flowers will set =
fruit.=20
So one should avoid picking flowers that have unusually =
long scapes that spring from unusually large leaves and also avoid =
picking flowers near walkways. But if picking a few CLS flowers can =
trigger or reinforce someone's interest in and respect for the natural =
world then it is flowers well spent. The look but don't touch attitude =
will literally pave the road to hell.
Hand pollination briefly is as follows-- 1) examine a =
flower and identify the two small pollen bearing structures and the =
single stigmatic surface. 2) take a spent plastic ink tube from a =
ball-point pen (about 2.5 mm diam) to act as a transfer tool. 3) check a =
flower for developmental stage. If ready for hand pollination then a =
waxy pollen deposit will stick to the plastic when the tube side near =
the end is rolled against a pollen structure. 4) this waxy deposit can =
then be transferred to a stigmatic surface by rolling the tube as =
before. I take pollen from one blossom and transfer it to a second (as a =
precaution) but suspect this is unnecessary because the initial pollen =
source plant also frequently sets.5) If few plants are ready then wait a =
few days and try again. The scape persists overwinter so pollinated =
plants can be marked with flagging tape, tied low on the scape, with =
year and plant number printed by marking pen.
Apart from the 10 % or so that deer munch, and who can say =
whether or not they would have set, all of my hand-pollinated blossoms =
have set fruit.
