Hello, I have a number of Oxalis obtusa color variants which are producing seed. Is this species like most Oxalidaceae in that seed will not survive storage at all and must be sown immediately? Blooming today: Lachenalia alba, mathewsii, orchioides; Hesperantha cucullata and a pink, pink-veined Hesperantha with invisible label. Soon to come: Hesperantha vaginata. My Lapeirousia jacquinii and oreogena seem to have set a good amount of seed, as has Babiana sinuata. The pale blue Lapeirousia set none. Leo Martin Phoenix Arizona USA
