프리지아 ‘Mauve Topaz’는 2006년 농촌진흥청 국립원예특작과학원에서 보라색 홑꽃 ‘Avila’ 품종과 보라색 겹꽃 ‘Blue Bayou’ 품종을 교배하여 획득한 종자로부터 2007년 연보라색다화성 홑꽃 프리지아 계통을 선발하였다. 2007년부터 2011 년까지 개화 생육특성검정 및 육성계통평가회의 기호도 평가를 통해 선발되어 2012년 직무육성품종심의회를 통해 ‘Mauve Topaz’로 명명하였으며 2014년 품종보호등록 되었다. ‘Mauve Topaz’는 RHS color chart V85A 연보라색 홑꽃 프리지아 품종으로 초장이 109.7cm로 대조품종 ‘Avila’, 103.7cm 및 ‘Blue Bayou’ 76.0cm에 비해 길고, 구근부패병에 강한 특징이 있다.
프리지아 ‘Mauve Topaz’는 개화소요일수는 136일로 대비품종보다 약 2 ~ 25일 정도 빠르며 소화수 및 소화장은 각각 13.0 개, 9.3cm이며 화폭은 6.2mm, 분지수 및 자구번식력은 4.3 개, 4.1배이다.
