小苍兰原产南非地中海式气候地区,那里夏季高湿干燥,冬季温和多雨。小苍兰适应了这种气候。秋季至翌年春季生长发育,至夏季形成球根休眠。 1816年,小苍兰被引入英国,1878年后,欧洲开始大量育种。1945年后,荷兰、美国等国家育出了植株高大,花朵硕大的4倍体品种。其后丹麦育出播种繁殖的品种。现在,荷兰是世界小苍兰育种中心。 小苍兰和剑兰有着密切的亲缘关系,但相对剑兰的高大挺拔。小苍兰显得纤细柔弱。也许是为了弥补“身材”的不足,它有迷人的香味。据说这种香味有抑制交感神经亢奋,降低血压之功效。遗憾的是小苍兰香精无法提取,有人透露,香水中的小苍兰香精都是人工合成的。 Freesia Native South Africa Mediterranean climate, where high humidity and dry summer, mild and rainy winter.

After 1945, the Netherlands, the United States and other countries gave birth to plant tall, huge flower 4-fold varieties. Since then, Denmark breeds sown breeds. Now, the Netherlands is the world freesia breeding center. Freesia and gladiolus has a close genetic relationship, but relatively tall and upright gladiolus. Freesia slender and delicate. Perhaps to make up for the lack of “body”, it has a charming scent. It is said that this flavor can inhibit the sympathetic hyperfunction, lower blood pressure effect. Unfortunately, freesia flavor can not be extracted, it was revealed that the fragrance of the freesia are synthetic.
