Alstroemeria aurea

Genus Alstroemeria

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 July 30, 2027 for a May 3 last frost. Too late for spring 2027 — that needed starting on July 29, 2026.

  1. Dry storage

    Duration: 180 daysTemperature: 70°F 21°C

  2. Sow and cover

    Temperature: 70°F 21°C

about 6 months from start to sowing. Then 70 days to germinate.

100% germination in 35–70 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. aurantiaca showed two Unusual features in its germination. Although both fresh seed and DS seed gave good germination, germination occurred in contrasting patterns. Fresh seed germ. 70-40(3/4 in 3rdw) whereas seed DS 6 m at 70 germ. 70(4/4 in 5-10 w). The long induction period for seed germinating directly at 70 is unusual, and inhibitors must be present. Germination is hypogeal.
