Blood Lily bulbs, Scadoxus multiflorus, also known as Haemanthus multiflorus. When you see several of the blood lilies in flower, you almost want to eat them, they are so bright, colourful and plum-red in color – until you realize that all lilies are poisonous to eat, but that fact doesn’t diminish their magnetic beauty and charm. The blood lily bulbs are about the size of a small hen’s egg and brown in color, and the blooms appear in late spring.

Saving the paintbrush lily from extinction
July 5, 2017
Summary: Since the 1990s, the Duthie Reserve in Stellenbosch, South Africa, is home to the only remaining viable population of Haemanthus pumilio in the world. It is described as South Africa’s most endangered bulb species, and probably the world’s rarest Haemanthus. A major project is now underway to conserve the remaining 60 individuals.
A major effort is underway to conserve the last remaining 60 individual paintbrush lilies (Haemanthus pumilio) in the Duthie Nature Reserve in Stellenbosch, South Africa, as well as increase the population through micropropagation.
Martin Smit, curator of the Stellenbosch University Botanical Garden, says more than a thousand of the paintbrush lilies once grew in the Duthie reserve. But the reserve is now less than a third of its original size, and the lilies have all but disappeared from previously known locations including Wellington and Klapmuts.
“The main reasons for its decline are the destruction of its original habitat (rhenosterveld) and invasives like Port Jackson (Acacia saligna). But the species is also dependent on fire to induce flowering and requires very specific conditions for the seedlings to survive. For various reasons the Duthie Reserve was last burned in 2004. For this type of vegetation, it is long overdue for another controlled burn,” he says. “Apart from being fire-dependent, Haemanthus pumilio also prefer ground that is dry in summer but waterlogged and marshy in winter. That is why the Duthie Reserve still remains the most suitable habitat to ensure the survival of this rare and critically endangered plant,” he adds.
While Smit has developed a management plan for the Duthie Reserve, two biologists from Stellenbosch University have obtained funding to employ tissue culture as a means of exponentially increasing the population.
Plant biotechnologist Dr Paul Hills and botanist Dr Gary Stafford have already collected leaf samples and seed from the existing paintbrush lily population in the Duthie Reserve, as well as from seven individuals from a now extinct population from Newton Commanage, Wellington, currently under the care of the Botanical Garden.
“Firstly, we are following a non-destructive strategy to mass propagate individuals from a variety of genotypes to allow for potential repopulation of dwindling populations in the Duthie Reserve and elsewhere,” Dr Hills explains.
At the same time, BSc Honours student Dominique West will use phylogenetic analysis to determine the genetic diversity within and between populations. This will allow for informed decisions to be made with regard to the use of genetic lines derived from micropropagation when it comes to repopulating and conserving the plants.
While the tissue culture samples and several seeds have already started growing in the tissue culture lab, the first seedlings will only be viable by the end of 2018.
“Because it so rare, Haemanthus pumileo is highly sought after by plant collectors locally and internationally. If we can get a viable population going, these will be spread to other botanical gardens and then some plants might be sold,” Smit adds.
