Mother-of millions (Bryophyllum spp.) is a native plant of Madagascar.  Its beautiful flowers have made it a popular garden plant in eastern Australia, especially in the drier, inland areas.  Unfortunately, mother-of-millions is highly toxic to stock!

The plant's ability to reproduce in such large numbers and to withstand droughts explains why it has escaped from gardens and rubbish tips to become a serious problem in many rural areas.  [Photo, above left - shows how mother-of-millions can take over in rural areas - next to Bruxner Highway between Bonshaw and Yetman NSW - click on photo for larger view

Mother-of millions is well named.  Each plant produces thousands of plantlets which detach to form new plants. This close-up photo [left] of an actively-growing young plant shows the reproductive potential of a just one plant.  A succulent, and drought-tolerant, most of these plant parts will survive.

Mother-of millions, particularly the flowers, can be VERY POISONOUS.  It continues to claim the lives of cattle throughout the north west.   In one of the worst reported cases in recent times, 125 head of cattle died after feeding on mother-of-millions on a travelling stock reserve, Moree area, 1997 (- Michael Kane, Moree).

Greatest risk is when the plant is in flower, and especially during dry times when feed is scarce.  And, when cattle are stressed or in unfamiliar territory (eg a new paddock) they are more likely to try plants they wouldn’t normally touch.

To quote from the Queensland Department of Primary Industries & Fisheries Fact Sheet [P33 Mar 00] on mother-of-millions, “POISONING SYMPTOMS in cattle include signs of dullness, loss of appetite, diarrhea and heart failure. There are two responses to poisoning; acute, where cattle die within a day, and chronic, where cattle may take up to 5 days to die. Cattle can slowly recover if insufficient plant material was eaten.  VET'S TREATMENT OF POISONED STOCK must occur within 24 hours of plant material consumption. The treatment is intense and needs to be given by or under the direction of a veterinarian.”

other-of millions is a hardy, drought-resistant succulent.   The plants grow upright (to 1m) thin “stems”, each containing numerous small “branches” or leaves.  There are also hybrid versions (see photo, right) which have similar flowers but serrated "branches". Each leaf produces many plantlets.  The plant flowers in the winter; this is when the plant is most dangerous to stock!

PLEASE NOTE that there other cacti-type plants with flowers similar to mother-of-millions.  Most of these other cacti-type plants don't have stems like mother-of-millions, which are generally about the same thickness from top to bottom.  Also, mother-of-millions plants don't have large, flat, serrated “leaves” at the base of the plant as does, for example, Cotyledon orbicularis (photo, right).  Be aware that these other look-alikes may still be toxic to animals – the best advice is to avoid all risk!

Poisonous Plants Handbook for Farmers & Graziers by EJ McBarron, Inkata Press ISBN 0909605297.  NSW Department of Primary Industries has on its weeds website a Primefact on mother-of-millions. Qld Dept of Primary Industries & Fisheries also has a very good Factsheet on mother of millions on its website.


Non-Chemical Options: Plants can be removed and burnt or stored in black plastic bags until completely destroyed.   Encourage a strong pasture competition.

Biological control:  "South African citrus thrips" are present in southern Qld and northern NSW.  The thrips are having a significant impact on large mother-of-millions infestations.  More information is available on the Qld DPI&F factsheet or by contacting North West Weeds. Photo (right) compares mother-of-millions with and without the effect of the thrips...

Chemical Options: Winter is the best time to treat mother-of-millions.  The plants are then in flower and easier to find. According to NSW DPI’s excellent booklet “Noxious and Environmental Weed Control Handbook 4th Edition”, chemical treatments for mother-of-millions include:
