Culture guide

  • Uses: Evergreen perennials for rock garden, pot plants
  • Exposure: Partial shade
  • Garden height: 6″ / 15 cm
  • Crop time: 8-10 months
  • Sow time: January-March for green pots; June-August for flowering in pots the following year
  • Sowing method: 2-3 seeds per plug
  • Germination*: Yields best germination results if exposed to a period of cool temperatures before temperatures are raised to
    60-65 °F (15-18 °C). Germinates in 3-6 weeks. Cover seed lightly with vermiculite after sowing.
  • Growing On: Transplant plugs after 6 weeks. Grow on at 54-65 °F
    (12-18 °C) in a well-drained, lime-free growing medium. Vernalization is required for flower initiation.
  • Media: Use a well-drained, growing perennial substrate with 0-15 % clay, 0-20 % parts (e.g. bark, sand, perlite),1-1,5 kg/m³ complete balanced fertilizer, 0-2 kg/m³ slow release fertilizer (3-9 months), iron-chelate, micronutrients, pH: 5.0-6.0.
  • Temperature: Grow at 12-18 °C or outdoors. In winter indoors frost free at 3-5 °C or outdoors. Outdoor fleece cover needed. In spring the plants start to grow for 4-8 weeks at 15-18 °C. Cold temperatures at 7-14 °C will increase the cultivation time. A chilling period (vernalization) is required for flower initiation
  • Fertilization: Low-moderate fertilization levels are required. Fertilize the crop weekly with 100-150 ppm nitrogen (at 2 kg/m³ slow release fertilizer in substrate), using a complete balanced fertilizer. Avoid high ammonium and high nitrogen levels. Don’t fertilize after mid September. In spring fertilize 100-150 ppm nitrogen of a complete balanced fertilizer. Prevent magnesium deficiency by applying magnesium sulphate (0,05 %) 1-2 times and in case of iron deficiency (above pH 6.0) apply iron-chelate for 1-2 times.
* Germination Stages (from seed to finished young plant)

Stage I Starts with the radicle breaking through the testa. The roots are touching the medium. Ends with fully developed cotyledons.
Stage II Starts from fully developed cotyledons. Ends with the fully developed true leaf or true leaf pair.
Stage III Starts from the fully developed true leaf or true leaf pair and ends with 80% of the young plants being marketable.
Stage IV All young plants are ready for sale and in the process of being hardened off. This stage lasts about 7 days.

The cultural recommendations are based on results from trials conducted under Central European conditions. Different conditions in other parts of the world may lead to deviations in results achieved.
