Description

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

(1) The accompanying photographic drawing shows typical flower and foliage characteristics of EURZ0019 with colors being as true as possible with an illustration of this type. The photographic drawings show flowering potted plants of the new variety.

(2) FIG. 1 was taken on Dec. 9, 2019 and shows a view of the bracts from the top of plant, on a plant about 21 weeks old.

(3) FIG. 2 was taken on Dec. 9, 2019 and shows a side view of the same plant.

DETAILED BOTANICAL DESCRIPTION

(4) The measurements were taken in Enkhuizen, The Netherlands at the end of November 2019 on 21 weeks old plants growing in a greenhouse. Culture of these plants had started in late June 2019 with planting rooted cuttings in 19 cm pots and terminal pinching about 2 weeks later. The plants were grown under natural day light in the fall (no black cloth to initiate earlier flowering) and at the moderately warm temperature of 18 C. for the bench heating. No use of Plant Growth Regulators (PGR).

(5) Color references are made to The Royal Horticultural Society Colour Chart (R.H.S.) 2001.
