Many gardeners have spent seasons pulling out Oxalis, satisfied it’s an unwelcome customer creeping by way of pots and cracks within the paving. But look nearer, and also you’ll see one of many Cape’s most fascinating botanical treasures – a genus that has perfected the artwork of survival whereas portray our landscapes in bursts of pink, yellow and white.
A local with aptitude
The best-known Oxalis of all, Oxalis pes-caprae, is acquainted to most of us because the cheerful yellow “suring” of childhood summers. Those tangy, lemony stems as soon as served as nature’s sherbet – a deal with picked straight from the backyard. Yet this is only one of greater than 200 South African species, a lot of that are native to the Cape Floristic Region.

Built to endure

These bulbs can dwell for many years, tucked safely underground, ready patiently for the appropriate circumstances to bloom once more. Some Oxalis patches could have been flowering in the identical spot for generations.

Others unfold clonally – creating an identical copies with no need to flower in any respect. It’s a survival technique that has helped Oxalis thrive in even the harshest circumstances.
Nature’s little alchemist
Perhaps most fascinating of all is how Oxalis works with the soil. Each seed carries tiny micro organism that may convert nitrogen from the air into vitamins the plant can use. “It’s an extraordinary evolutionary trick,” explains Professor Léanne Dreyer of Stellenbosch University, who has spent almost three many years finding out and conserving Oxalis. “These plants are perfectly adapted to the Cape’s nutrient-poor soils – it’s pure genius.”
Guardians of the genus
At the Stellenbosch University Botanical Garden, Professor Dreyer and her workforce have constructed the world’s largest residing Oxalis assortment – greater than 180 species, every representing a bit of South Africa’s floral heritage. Among them are critically endangered species like Oxalis pseudo-hirta, threatened by habitat loss to vineyards, and Oxalis fragilis, as soon as thought extinct till the workforce rescued it from a development website.
Through cautious hand-pollination and propagation, these crops are being given a second probability – proof that conservation isn’t nearly saving the uncommon and showy, but additionally the small and delicate.
A quiet reminder
