DELPHINIUM GRANDIFLORUM, CHINESE DELPHINIUM, LARKSPUR 'Summer Cloud'

We are proud to introduce another color in the highly acclaimed Delphinium 'Summer' series. The new 'Summer Cloud' is like a beautiful painting, combining blue and white to create a beautiful bi-color flower, which is reminiscent of summer clouds over a blue sky. With its dainty fl owers and lacy foliage, the Delphinium 'Summer' series appears to be very fragile, but do not let its appearance fool you. 'Summer Cloud' thrives in heat and humidity without stretching like other Delphiniums on the market. Early flowering combined with a well-branched habit make 'Summer Cloud' a must have in the garden. At 25-30 cm 10-12'' 'Summer Cloud' remains compact and matches the rest of the 'Summer' series.

TECHNICAL INFORMATION

Garden Height:   30 cm - 11,81 inch

Crop Time:   Plug crop: 6 weeks; Green pots: 12-14 weeks; Flowering pots (from sowing to fl ower): 16-20 weeks

Seed Form:   Raw Seed

Seed Count:   0 K/g

Sowing Time:   December-May

Sowing Method:   2-3 seeds per plug

Germination:   Stage I: 14-18 days at 20-22 °C 68-72 °F; Stage II: 15-20 days at 17-20 °C 63-68 °F, Stages III+IV: 20-25 days at 13-17 °C in media with low soluble salt levels and pH: 5.8-6.5. Cover seed lightly with vermiculite or sand after sowing. Keep soil slightly moist but not wet.

Growing On:   6-9 weeks after sowing transplant 1 plant into a pot (9-10 cm) 4'' and 3 plants into a bigger pot (13-15 cm) 6''. Transplant the plug not too deep in substrate.

Media:   Use a well-drained media, pH: 5.8-6.5.

Photoperiod / Light:   Day length neutral plant. In early spring additional assimilation light combined with long day (14 h) will improve the plant quality and will decrease the cultivation time by 2-3 weeks.

Temperature:   Grow at 13-16 °C 55-61 °F or outdoors.

Fertilization:   Moderate fertilization levels are required.

Cultural Hints:   Temperatures above 29 °C 84 °F can cause flower abortion. Temperatures below 13 °C 55 °F under short days will cause plants to form rosettes and delay flowering.

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.
