seed germination in Lilium
Sat, 20 Mar 2010 14:55:12 PDT
Some interesting information and data is building up on the germination times of taxa within Lilium based on the recent and current experiments here.

For those of you who are not troubled by rounding up cats but may be contemplating further seed sowing this year, Spring or Autumn, the time scales for even those taxa which are reputed to take over a year, and more, can be dramatically foreshortened through the use of vermiculite. 

This current Autumn & Winter seed sowing, Spring is still some weeks off here, has seen over 160 different seed lots sown, all of botanical taxa frequently 2 - 3 plus replicates per species from every part of the world wide lily distributions and have involved both species and subspecies, recent as well as some quite old material, [in one case from 1987] and to date the longest time taken for any Lilium including L. martagon s.l. has been 82 days, the general run of time taken to first sprouting is in the range of 14 to 33 days. I think it is now possible to see a way to avoid delayed germination whether epigeal of hypogeal. Should anyone be interested in the very simple methods please get in touch and I would also welcome learning what other people's experiences are and / or have been with botanical taxa in Lilium. I have not nor am I likely to, do any investigations with hybrids of multibrids as these don't feature in the work here at Auchgourish Botanic Garden but I would surmise the outcomes with those sorts of lily would most probably be much the same.

Happy geophyte gardening for 2010.  Iain
