Author Message   Carol23  Posted on Monday, December 04, 2006 - 03:18 pm EST :    Both of these Cyclamen have a larger than normal first leaf. One has been garden grown for several years now while the other is in a pot. Are these long petioles in the genetics? In quite shady areas I've noticed tubers with compact foliage and short petioles. I purposely exposed the petiole on the garden grown plant since it's probably at least a foot long! The plant in the pot is from a similar source and has the floppy habit as well. The parent plant of the second one also sprawled about in a friend's garden. My plant was a seedling beneath it. For those of you having seen these in the wild, what have you noticed? How about your hederifolium in the garden? Are there petiole length differences from one tuber to the next?

I had thought it was because they were indoors and not under ideal conditions. It will be interesting to see other responses.

All evidence shows for me that petiole growth (lenghth and strength) is controlled by light exposure of the leaf shoot. In exposed tubers in the wild the petioles are very short and strong and the plants are compact while under a layer of leaf litter or in deep compost they can creep far away from the tuber. Also in wild colonies I have often observed that one leaf is much larger than the rest; normally this is the first leaf developing under more favourable conditions than the rest which come later and where there is much competition for water and nutrients among them. That potted plant has a very nice leaf. Matthias - Southern Germany, Zone "7"   Carol23  Posted on Tuesday, December 05, 2006 - 07:48 am EST :    Matthias, thanks for that information. There's quite a bit of leaf litter around that tuber. The potted Cyclamen was in a seed lot of " Bowles Apollo Group". Should that name be used? Does anyone grow 'Bowles Apollo' with a uniform appearance?

I think this doesn't just apply to cyclamen. Flowers are the same, it's as though the first leaf or flower is just bursting to get out. Galanthophile - Ann (Northern England), Zone "8"
