'Bella Blue'
The newest addition to the Prunella program, 'Bella Blue' lives up to its name. Beautiful and dainty, 'Bella Blue' is covered with masses of violet-blue flowers throughout the summer. At 15-20 cm 6-8'' tall, 'Bella Blue' is an excellent addition to mixed combinations, and is also extremely showy in the landscape. 'Bella Blue' is very well branched and produces masses of flowers,
making it ideal for pot production throughout the season. Short crop times and low inputs make this Prunella a grower favorite!

|
|
| Sowing Method: | |
Multiple sow, 3-5 seeds per plug
|
|
| Germination: | |
Dark germinator. Provide a thin Vermiculite cover, maintain uniform moisture level. From Stage II on reduce moisture level and reduce the temperature to 18 °C 64 °F. Grow on maintaining a uniform moisture level.
|
|
| Growing On: | |
Transplant using 1-2 plants per 10-12 cm 4'' pot or 3 plants per 13-15 cm 6'' pot.
|
|
| Media: | |
Use a friable humic substrate with a pH of 5.5-7.0.
|
|
| Photoperiod / Light: | |
When forcing the plants very early in spring, providing long days (14 hours) with
supplemental lighting and warm conditions will
reduce crop time.
|
|
| Temperature: | |
15-18 °C 59-64 °F, start ventilating at 20 °C. When plants have established in the pot
reduce temperature to 12-15 °C 54-59 °F or place the plants outdoors. Plants may be overwintered in house at 3-5 °C 37-41 °F or in the field. Cover the plants in the field with a non-woven cloth to
protect from direct sunlight. Force warm at 15-18 °C 59-64 °F or cold at 12-15 °C 54-59 °F. The cooler the growing temperature, the more compact the plant habit and the better the plant quality.

|
| Fertilization: | |
Requires low nutrient levels.
|
|
| Cultural Hints: | |
Keeping the media uniformly moist but on the dry side will help prevent mildew problems.

* 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. |
Hint
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.
