The seeds of the two species I ordered via AGS Seed
Exchange. I sowed them on January 1st (L. lankongense), respectively on February 3rd (H. gracilifolius). The seeds of both
species germinated on March 13th. I was a little surprised because
sown seeds were placed on the stairs to the attic, in the dark, where the
temperature ranged between 7 and 12 degrees Celsius.
Lilium lankongense is a species found in northwest Yunnan and southeast Xizang in China growing at altitudes between 1800 and 3200 metres. Normally, the seeds of L. lankongense will germinate within 15 to 35 days (http://www.the-genus-lilium.com/germination2.htm).

In contrast, H.
gracilifolius grows in areas with mild climate - la Sierra de los Padres,
Partido de General Pueyrredón, Provincia de Buenos Aires, Argentina
(Echeverría, Alonso, 2010), southern Brazil, near Torres and Uruguay, near
Punta Ballena and Punta del Este (Howard, 2001). Yet H. gracilifolius is able to
germinate at relatively low temperatures. At higher temperatures (around 20°C)
but probably germinate faster (Echeverría, Alonso, 2010).

The photos of seedlings are taken less than a month
later after germination. The plants are placed under the fluorescent lights that
shine only during the day, at 15-18 °C.
