| Historical: | After a brief appearance in 1936 in Scotland (as Astilbe) this aruncus was lost from sight. In the seventies it reappeared, having been reintroduced by some Swedish botanists. Unfortunately they had brought back only male plants. Dick Lighty of the Longwood Botanic Garden, USA, arranged to bring back seeds and shared them with K. Jelitto, which ensured the seed crop in Europe. In 1984 Jelitto were then the first seed company in a position to sell this species of aruncus seeds. |

| Sowing Direction: |
(1) Cold-germinators are still referred to as frost-germinators, although this isn’t quite correct. The sowing must be kept warm (about +18 to +22°C) [about 64 to 72°F] and moist for the first 2–4 weeks. After this period the sowing must be kept at a cold temperature (between –4 and +4°C) [between 25 and 39°F] for another 4–6 weeks. Colder temperatures of –5°C [23°F] are only advantageous for most species of the Ranunculus family. It is not so important if the temperature is higher or lower during the cooling period, but the cooling period has to be prolonged because the synthesis of the germination inducer, hormon-like acid, slows down or comes to a standstill.
