Plant Description

Life Cycle: Perennial
Family: Portulacaceae
Origin: USA: California and Southwest Oregon
Special Features: Mixture of many newly bred colors and forms. The best existing cotyledon hybrids today. Round flowers also semi-double. A very attractive plant for container production and will have impulse appeal in garden centres. Gold medal prize winner at the IGA in Stuttgart 1993 (Krämer). In warmer conditions a northern exposure with a cool root run is preferred.
Historical: Introduced by JELITTO PERENNIAL SEEDS in 1989. The genus is named after Virginian, Meriwether Lewis, leader of the Lewis and Clark expedition, the first to cross the North American continent in 1804-1806.

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.
It is beneficial to cover the sowing with snow during the cooling-period. The temperature below it usually keeps in the optimum range of –4 to 0°C [25 to 32°F]. The sowing is kept moist, and the melting snow helps to destroy the shell, which is advantageous for the germinating seedling. After this cooling-period the sowing may not be immediately exposed to high temperatures. The most effective temperatures are between +5 to +12°C [41 to 54°F], even if germination has started. The best location for this sowing, even in March, April and May, is the open field, the cold frame or a cold greenhouse.
