I was fascinated by the description of the life cycle of Lewisia rediviva in Davidson's book on Lewisias.

http://www.amazon.com/Lewisias-B-Leroy-Davidson/dp/0881924474/ref=sr_1_2...

He notes that after the blossom has been fertilized, the withering petals and stamens fold inward to wrap the ovary in a tidy package bound within the six to nine sepals.  The seed takes only a short time to ripen and then the plant's real genius emerges.  The stalk disengages and the papery calyx and its enclosed capsule cartwheel away in the wind.  During the journey the capsule splits revealing the shiny black disc-shaped seeds which adhere in a little clutch for a while.  Their release completes the bitteroot's life story.

The seeds on the Lewisia rediviva in our garden disappear very quickly and they are thus hard to observe and collect.  This year one flowered in the Alpine Shed and I carefully kept the seed capsules from blowing away.  The first picture below is the wrapped ovary and the papery calyx as described by Davidson.  The second photo shows the split seed capsule. It must be a real challenge to collect wild seed. I was lucky enough to get wild seed from Ron Ratko.

They are so beautiful, David.  I've had mixed success with them in the garden.  They'll bloom for a few years and then disappear.  I especially like the white ones with the pink stamens.  They're so easy from seed, I'll try them again.  I usually keep them in the pot the first year and plants them out the second year.  Don't know if that's necessary.

To try and capture the amazing flowers and habitat, I took some video footage of the Lewisia rediviva on our Mount Kobau trip and have posted it on YouTube:

I included a music track from Pierre Fournier's stunning rendition of the Bach suites for solo cello.  However, YouTube does a digital match, figures out what the track is and determines the copyright status. If the music is deemed copyright they include ads on the video and presumably compensate the artist in some way.  It is easy enough to click off the ads.  Unfortunately the copyright requirements are such that the video is blocked in Germany.  If anyone in Germany wants to see it, please let me know and I will upload a version without Bach in the background.

David:  SUPERB video, and with the music selection, BRILLIANT!!!

On a side note, what software do you use to create such Youtube multimedia presentations?

Thanks Mark for your kind comments.

I am a long time Mac user so just use the software that comes with Mac. 

iMovie integrates well with iPhoto and iTunes so it is quite easy to put it all together.  I like the version of iMovie known as iMovieHD which dates from about 2006.  Subsequent editions of iMovie lost important functionality so I stuck with the old version.  I understand the very latest iMovie has restored the functions I need but I have not tried it yet as I am used to the old version.

Once you have completed the editing and added the sound track you convert the movie to Quicktime which can then be uploaded to YouTube. I fail to understand how YouTube can provide all that storage space for free.

David,
May I congratulate you on your beautiful videos which, I'm ashamed to admit, I have only just discovered.
Your hikes and flower portraits are stunning and deserve a much wider audience.
I was particularly taken with the Skyline Divide/Chowder Ridge hike (http://www.youtube.com/watch?v=WRUVQ1yOAAs&feature=related)

... what month was this hike completed please?
There has been some discussion on the AGS site recently about the need for video/television exploration to be made in the florally rich mountains of the world (in much the same way that the world's fauna has been rigorously explored) and these lovely examples simply emphasise this desire.

Cliff:

Timing for the Skyline Divide Hike is very much dependent on the snow conditions. We usually go every year around mid-August - it is something of a pilgrimage for us. However this year there is still quite a bit of snow on the ridge according to reports from the Mt Baker National Forest. The info is near the bottom of this table:

We may go up there this year in September!

Cliff:
I agree with you.  It always bugs me when there is a TV program on the natural history of wherever and the entire program is only on the fauna.  If there is any flora covered it is nothing more than a backdrop with no information on plant names or plant habitat.

David, you mentioned Mt. Baker National Forest.  One of my favorite hikes is there, I think - Corral Pass.  A lovely steep scree with huge mats of Penstemon rupicola and Collomia debilis v larsenii for starters.  Just a spectacular spot - have you been there?
