프리지아 ‘Sweet Lemon’은 2007년 농촌진흥청 국립원예특작과학원에서 흰색 겹꽃 ‘Teresa’품종과 노랑색 반겹꽃 ‘Yvonne’ 품종을 교배하여 획득한 종자로부터 2007년 연노랑색 향기가 강한 겹꽃 프리지아 계통을 선발하여 품종으로 개발되었다. 2008년부터 2014년까지 개화 생육특성검정 및 육성계통평가회의 기호도 평가를 통해 선발되어 2015년 ‘Sweet Lemon’ 으로 명명되었다. ‘Sweet Lemon’은 연노랑색(RHS color chart Y2B) 겹꽃 프리지아 품종으로 화폭은 6.8cm이며 분지수는 6.7개로 다수확성 품종이다. 초장은 99cm로 초세가 강하며 대조품종 ‘Yvonne’ 91.7cm에 비해 34.7cm 더 크다. ‘Sweet Lemon’의 소화수 및 소화장은 각각 10.7개, 7.7cm로 ‘Yvonne’ 9.7개, 8.3이며 개화소요일수는 126일로 대비품종 보다 약 20일 정도 빠르다. 이 품종의 절화수명은 약 8.7일이며 자구번식력은 5.6배로 대조품종에 비해 우수하다. GC/MS를 이용한 향기분석 결과 총 58개의 방향성 화합물이 검출되었으며 주요성분은 linalool, alpha-Terpineol, alpha-Selinene, limonene이었다.

Freesia (Freesia hybrida Hort.) ‘Sweet Lemon’ was developed for the cut flowers in National Institute of Horticultural Herbal Science, Rural Development Administration, Korea in 2015. This hybrid was crossed and selected from ‘Teresa’ and ‘Yvonne’ in 2007. Morphological characteristics of the selected freesia hybrid were investigated for 5 years from 2009 to 2014, and then it was named ‘Sweet Lemon’ in 2015. ‘Sweet Lemon’ has double and lemon petals (RHS color chart Y2B). The average flower diameter was 6.8 cm and the average yield is 6.7. The growth of the plant is vigorous and the average plant height is 99.0cm, which is 34.7cm higher than the standard cultivar ‘Yvonne’. The average floret number per stalk of ‘Sweet Lemon’ was 10.7, and stalk length was 7.7 cm. The average days to first flowering of ‘Sweet Lemon’, 126 days, was approximately 20 days earlier than the control cultivar. It’s average vase life and yield is 8.7 days and 5.6 cormlets per plant, respectively. Totally 58 of volatile compounds were identified using gas chromatography-mass spectrometry (GC-MS), the major components were linalool, alpha-terpineol, alpha-selinene, and limonene.
