Hi,I guess I do not really understand what a luminata is. Can you please explain it?Wendy Zone 5 a nice 30 degrees and sun and calm today
Wendy,

This is the definition from the Ad Hoc Committee (Keppel, Nelson, Stahly, Ch.) reporting in the 1972 AIS Bulletin. I   not know if it has been modified since then:

We therefore present the following definition: "Luminata is a genetically reproducible anthocyanin (violet-Ed.) pattern having its color present in an irregular  marbling in the central areas of the petals and absent to some degree in the peripheral areas. The marbling effect is produced by non-anthocyanin veining (white, yellow, pink, or orange), and there is no anthocyanin in an area to either side of the beard (which area may or may not extend to the edge of the petal) or in the beard itself.

"The luminata pattern can appear by itself or in combination with the plicata pattern; when in combination the patterns superimpose one upon the other, leaving practically none of the flower conspicuously absent of anthocyanin coloration. The combination condition is generally referred to as luminata-plicata, or 'lumi-plic'."

Descriptively, then, the luminata has these characteristics:
l. The beard and an area to either side o£ the beard are white or are colored with carotenoid pigmentation (yellow, pink, or orange).

2. Style arms are similarly colored, although there may be light anthocyanin-like coloration on the upper portion.

3. Petals are marked in irregular patterns (described as brushed or marbled) with an anthocanin color which diminishes in some degree toward petal edges. The marbling is produced by veining of a non-anthocyanin color (white, yellow, pink, or orange). Petal margins may have a pronounced non-anthocyanin edge or rim, or the edge may have only a slight lightening of coloration; or the effect may be anywhere between these extremes. The degree of anthocyanin marking ranges from very heavy and dark to a very light brushing.
