This source reports two treatments. Both are shown.

Protocol 1

DerivedN. C. Deno, 1993

Difficulty Low Rated by us, not by the source.

Start around March 8, 2027 for a May 3 last frost.

  1. Cold moist stratification

    Temperature: 40°F 4°C

Germination happens during step 1, in 28 days.

78% germination in 14–28 days.

Alstroemeria (Amaryllidaceae). Four samples of wild collected seeds were obtained from the Archibalds. All four samples were collected in altitudes of 5000-8000 feet so that they may be hardy here and provide the basis for further efforts to breed hardy Alstroemerias. Already Don Hackenberry has two fine clones that have survived several winters in Central Pennsylvania. Germination is generally best at 40 with a prior 4 w at 70 sometimes improving the germinaton. A. umbellata) germ. 616 in 2-4 w at 40 if the seeds had been subjected to a 4 w period at 70 first. Without this prior 4 w at 70 the seeds germ. 40(3/6 in 4-7 w). This last sample was shifted to 70 after 7w at 40 whereupon 2/6 germ. in 1-3d. A. umbellata germ. 40(7/9 in 2-4 w). A prior 4 w at 70 lowered the germination to 4/9 with the rest rotting.
