Description

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

[0028] The accompanying photographs illustrate the overall appearance of the new Phlox plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Phlox plant.

[0029] The photograph on the first sheet is a side perspective view of a typical flowering plant of ‘Appottpi’ grown in a container.

[0030] The photographs on the second sheet are close-up views of typical inflorescences (upper photograph) and typical leaves (lower photograph) of ‘Appottpi’.

DETAILED BOTANICAL DESCRIPTION

[0031] The aforementioned photographs and following observations and measurements describe plants grown during the summer in 15-cm containers in an outdoor nursery in Mijdrecht, The Netherlands and under cultural practices typically used in commercial Phlox production.
