A lovely extremely fragrant native lily with trumpet shaped flowers with strap-like petals that gently reflex. Young blooms begin life an ivory white (dark purple speckles within) then age to a pink to purple. Because the flowers open in succession over the blooming season, so you will see white to pink flowers at the same time. Plants grow to 1-2 meters in height with a 60 cm spread. Grey green somewhat broad-ish leaves are spaced in dense whorls along the lower 2/3 of the stem. Co-evolved with our wacky climate and soils so it will withstand summer drought when established.

They’ve also germinated in the fridge within 2 months of their cold stratification cycle without previous warm stratification.
