Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The accompanying color photographs illustrate the overall appearance and details of flower form, color and structures of the new cultivar 12-01-ZEU, showing the colors as true as it is reasonably possible to obtain in color reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description, which more accurately describe the actual colors of the new Euphorbia cultivar.

DETAILED BOTANICAL DESCRIPTION

[0025] Plants of the new cultivar 12-01-ZEU have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity, day length, and fertility level without, however, any variance in genotype.

[0026] The aforementioned photographs, together with the following observations, measurements and values describe plants of the new cultivar 12-01-ZEU as grown in Hjortebjergvej, Denmark, under conditions which closely approximate those generally used in commercial practice. Plants of 12-01-ZEU were grown under the temperature range of about 20-22 C. for a day length of about 12 hours. Artificial light of intensity of 50 Watt/m.sup.2 was used when the intensity of the day light was less than 40 Watt/m.sup.2. Water with an electrical conductivity of about 1.6 ds/m (deciSiemens/meter) was used for irrigation. All plants were grown in 11 cm pot in a glass greenhouse.

[0027] Color observations were taken under natural light, and the color references are made to the R.H.S. Color Chart of The Royal Horticulture Society of London, except where general color terms of ordinary significance are used. [0028] Botanical classification: Euphorbia milii Desmoul.
