Midland Diary No 44 - Seed Collection StartsGo to latest contribution by Anne Marise GIBSON, 02 August 2011, 13:24. Go to bottom of this page.
My Diary No 44 shows a little kit that I put together so that I am ready to collect seed at any opportunity.
I've also been busy with a couple of new projects.
Very professional seed collecting kit Diane. It beats my plant pot with some kitchen tissue stuffed in the bottom and knicking the kitchen scissors, into a cocked hat. Nice little crevice garden too.
It is very distinctive how cyclamen stems coil and take the seeds down to the ground.
My questions is, where does the twist come from.
I'd been going to say that if the flowers follow the sun there'd be too many twists. But I suppose there are plants whose stems twist both clockwise and anticlockwise. Hence Shakespeare quote about woodbine and honeysuckle entwining.
Has anyone ever done a stop motion photo of cyclamen seed pods developing.
David, the issue of coiling cyclamen stems is very interesting. I am tempted to try to photograph the event, but I'm not sure of the timescale involved. I think that most cyclamen coil from the top downwards, but C rohlfsianum coils from the bottom upwards. C graecum starts at both ends and sort of meets in the middle. And C persicum doesn't coil at atll but the fruits just hang from the end of the pedicel. I suppose the benefits of the fruit coiling down are to protect the fruit over the long ripening time and also when ripe, the seed is then at ground level ready to be dispersed by ants who are attracted by the sticky coating. As for clockwise and anticlockwise, we'll have to take a look at that!
A quick look at the PBS wiki shows c. coum spiraling anti-clockwise (going from tuber to seed) and c. hederifolium going clockwise.
