SITF confirms this plant as Gongora leucochila (Alba color form) (Aug 2025). This plant matches the drawings and photo of G. leucochila in Rudolf Jenny's "Monograph of the Genus Gongora" with the exception that the description indicates a maximum inflorescence length of 20 cm and up to 15 flowers. There has not been a valid taxonomic description of an alba form published; however, there is an Award photo of Gongora leucochila 'Woodstream' CHM , which is an albinistic form in the AOS Bulletin, 2012, Vol 7, pg 395 and the award listed in the OP that supports this color form.
