Mtunzini Fun Fact: The Natal Lilly by Office | Nov 23, 2020 | News Mtunzini Fun Fact: Meet the Natal Lily also known as Crinum moorei. It blooms from Dec to Jan. According to the Red List of South African Plants, Crinum moorei is Vulnerable (VU). Its wild population is decreasing, and has declined by at least 20% over the past 70 years. This decline is caused by harvesting of the bulbs for the traditional medicine plant trade, and due to infestations of the Amaryllis Borer. It is used in traditional medicine for urinary tract infections and to treat cattle. The bulbs are also used by traditional healers to cleanse the blood, treat infected sores and even acne.
