About the plant

What it is and where it grows — not part of any germination protocol.

Note
An unresolved name: recorded by WFO, flagged doubtful by GBIF.

Toxicity is noted only where a source states it. No note here is not a finding of safety.

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 February 13, 2027 for a May 3 last frost.

  1. Cold moist stratification

    Temperature: 40°F 4°C

    96% germinated at 40 itself.

  2. Warm moist stratification

    Temperature: 70°F 21°C

    A further 4% after the move.

No stated waiting before sowing. Then 51 days to germinate.

96% germination — first up on day 48, then 40% a day.

The rate reads '40%/d' in the scan, which is how it prints '40%/d' elsewhere.

This source doesn't state how long.

Hebe (Scrophulariaceae). H. guthreana germ. 40 (96%, i. t 48 d, 40%/d)-70(4%) and 70(5%). The seed sown at 70 might have given better germination if the experiment had been continued.

Protocol 2

DerivedN. C. Deno, 1993

Start around March 15, 2027 for a May 3 last frost.

  1. Sow and cover

    Temperature: 70°F 21°C

No stated waiting before sowing. Germination time not stated; 21 days assumed.

5% germination.

Deno thought 70 might have done better had the experiment run longer.
