Karoo Fireworks: Aridland blooms at Karoo Desert NBG

Karoo Desert National Botanical Gardens is one of SANBI’s oldest botanical gardens. Located in the town of Worcester, two hours from Cape Town along the N1, this beautiful garden is well worth the visit. Karoo Desert NBG showcases the rich diversity of unique and extraordinary flora that comes from the more arid parts of South Africa including the Richtersveld, Succulent Karoo and Klein Karoo.

As we enter the hotter summer months and the Karoo veld hunkers down to survive the increased heat and aridity, we take a look back at the spectacular blooms that wow visitors to the garden during late spring and early summer. Thanks to the horticultural skill and foresight of the gardens’ staff, Karoo Desert NBG offers a veritable firework display of blooms in one of the country’s most arid and water scarce botanical gardens, continuing well into October and the start of the summer season. Their work stands testament to what can be achieved when gardening in South Africa’s relatively dry climatic zones. It is a garden that inspires.

The majority of late spring and summer colour at Karoo Desert NBG comes from the vygies. So what is a vygie? The word ‘vygie’ is a South African term derived from Afrikaans and refers to a low growing, sometimes creeping, sometimes shrubby group of succulents with often spectacular flowers from the Aizoaceae family. Many make popular and easy to grow waterwise garden plants and are the mainstays of the September and October blooms at Karoo Desert NBG.

One of the most vibrant of this group that makes Karoo Desert NBG famous is Drosanthemum speciosum, easily recognisable with its intense red flowers. There are also a few other colour forms, with this species also coming in orange, yellow or even pink. A truly local bloom, it is also known as the Worcester-Robertson vygie or bergvygie. They are also known as ‘municipal workers’ in reference to their flowers opening at 9am and closing for the day at 5pm. In cultivation their grow easily from seed and can be found in Mediterranean climate gardens worldwide. For the best flowering displays they should be replaced every three years as the plants become more woody with age.

Another mainstay of Karoo Desert NBG is Drosanthemum bicolor, another small shrubby vygie, with stunning red and yellow flowers. In Afrikaans it is known as the ‘tweekleurporseleinbos’. In the wild it grows on hillsides in the western Little Karoo, growing on soils derived from Malmesbury Shales. It is thought that bees pollinate the brightly coloured flowers of this species. Following pollination seed capsules are produced that only open to disperse the seeds inside when rain comes, thus ensuring more likely survival of any newly germinated seedlings. Drosanthemum bicolor is also easily cultivated and will grow in most gardens across the Western Cape.

The vibrant deep pink blooms of Lampranthus multiradiatus can also be seen flowering in late spring and early summer at Karoo Desert NBG alongside the red, orange and yellow Drosanthemum. Those crafting this garden are not afraid to place vibrant and contrasting colours together. In fact, the genus name ‘Lampranthus’ actually means ‘bright flower’, derived from the Greek words ‘lampros’ meaning ‘bright’ and ‘anthos’ meaning flower. There are more than 140 species of Lampranthus, mainly confined to the winter rainfall areas of the Western Cape. In cultivation they are easily grown, attracting bees into the garden.

As climate change makes water an ever scarcer commodity in South Africa, gardeners need to become more innovative with their plant choices, growing indigenous and waterwise species where possible. Karoo Desert NBG has shown us how locally indigenous vygies can be used to create a bold and spectacular display, leading the eye through the gardens to the mountains beyond. It shows us what is possible in our own gardens, bringing colour as we garden for the future.

False Bay Birdathon a soaring success

On October 19 the sixth False Bay Birdathon was held by the Cape Town Environmental Education Trust (CTEET) in partnership with the City of Cape Town and the Cape Bird Club. The event was hosted on the eastern shores of Zeekovlei near Pelikan Park in the City of Cape Town’s False Bay Nature Reserve.

Community and Biodiversity: Visiting the Darling Wildflower Show

Taking place annually on the third weekend of September, the Darling Wildflower Show is the second oldest wildflower show in the world. Visitors come from far and wide to enjoy this highlight of the West Coast’s event calendar, organised by volunteers from the Darling Wildflower Society with support from members of the BotSoc West Coast Branch.

Above: View over the picturesque small town of Darling in the Swartland from Darling Renosterveld Reserve.

The small town of Darling is located an hour’s drive north of Cape Town, inland from the West Coast town of Yzerfontein. It was founded in 1853 on the farm Ormonde, formerly known as Langfontein. Today this picturesque town has blossomed into a thriving centre for festivals, performances, quality food, beer and wine and much more.

Top: Lachenalia pallida. Above: Monsonia speciosa. 

Within and around Darling are no less than seven wildflower reserves, conserving and showcasing the beauty of the region’s critically endangered Swartland Renosterveld. The majority of this highly biodiverse vegetation, known for its plethora of beautiful geophytes, has been lost to the plough for agriculture. These reserves are some of the last precious habitat for many threatened species that call the Darling area home.

The Darling Wildflower Show is an annual celebration of the area’s wildflowers and biodiversity, bringing together dedicated volunteers from the community to construct a series of beautiful themed exhibits to showcase and raise awareness about the Swartland’s Renosterveld flora.

Above: Carnival dragon in the wildflower displays at the 2019 Darling Wildflower Show.

This year’s flower show was the 102nd with the theme ‘a carnival of wildflowers’. Visitors to this year’s show could also enjoy live music, a craft and gourmet food market, a display of vintage tractors and more. The tractor ride was one of the highlights, taking trailers of visitors nestled on haybales out to a wetland on the neighbouring Oude Post Farm not normally open to the public to view the wildflowers in habitat.

The Darling Wildflower Show also serves as an information point for those wishing to visit the surrounding wildflower reserves, reaching their flowering peak in the second or third week of September. It is easy to combine a visit to the show with a leisurely ramble through the Renosterveld with its stunning spring blooms.

Above: Display tables at the Darling Wildflower Show showcase examples of the key flora of the Darling area.

Shortly after turning off the R27 West Coast road towards Darling, the Tienie Versveld Nature Reserve can be found on the left. The land on which the reserve now lies was once part of the farm Slangkop. In 1958 Marthinus Versveld donated this 20 ha piece of Renosterveld to what is now the South African National Biodiversity Institute (SANBI). Many rare and threatened Swartland Renosterveld plants grow here, including some only found in the Tienie Versveld Reserve and nowhere else.

Above: Darling Renosterveld Reserve in the evening light.

Darling Renosterveld Reserve lies above Darling behind the primary school and was also donated for conservation by the Versveld family. A beautiful circular walk showcases a variety of different Renosterveld plants, offering stunning views over the town and the sweeping agricultural landscapes of the Swartland beyond.

Waylands Wildflower Reserve, located 6 km east of Darling on the R307, is also known for its spectacular Renosterveld wildflower displays. It is part of Waylands Farm that has been owned and farmed by the Duckett family since 1865 with the reserve founded in 1922. Waylands Wildflower Reserve is home to around 300 different plant species and many species of birds. It is open to the public during daylight hours throughout the spring season.

Chelsea in the Lowveld

The BotSoc Lowveld Branch would like to extend their thanks to all those branch volunteers who assisted with the building and opening of the ‘Chelsea in the Lowveld’ exhibit at Lowveld National Botanical Gardens. From the 22 to 30 June the exhibit was on display at the gardens.

Every year delegates from SANBI travel to London, UK to exhibit at the Chelsea Flower Show, one of the UK’s most prestigious flower shows. The Chelsea Flower Show, founded in 1913, is held each May in the grounds of the Royal Chelsea Hospital. Once again the SANBI team won gold this year for their exhibit.

The Chelsea exhibit was designed by Leon Kluge, former Lowvelder and son of previous garden Curator Johann Kluge. He was lucky enough to grow up with Lowveld NBG as his backyard. It therefore seems only appropriate to bring Chelsea Flower Show to the Lowveld.

The finished ‘Chelsea in the Lowveld’ exhibit covered 18 square metres with the original Chelsea exhibit covering 135 square metres. Kluge presented during the exhibition to BotSoc members and the local garden club on the trials and tribulations of building the main exhibit in London.

The Cape Dune Molerat Trail in Wilderness was selected by Di Turner, Outramps CREW team leader, as it provided both high diversity in flowers and a vigorous bit of exercise in a short time frame. Anyone who knows this CREW group knows that the hustle up the path is also very important!

Top: Gladiolus rogersii in bloom was outstanding all along the trail. Photo: Antonia Xaba. Above: Garden Route Branch Treasurer Pauline Cloete and Chair Jo-Anne King (kneeling) stop to photograph a wild Freesia. Photo: Antonia Xaba.

Buchus on show included Agathosma ovata (False Buchu) and Agathosma apiculata (Garlic Buchu), with beautiful bulbs Freesia leichtlinii subsp. alba (White Freesia) and Gladiolus rogersii (Riversdale Bluebell) peppering the entire walk.

Erica verticillata: Rewilding an iconic species on Rondebosch Common

Written by Zoë Poulsen and Alex Lansdowne. Photos: Zoë Poulsen

The story of Erica verticillata is one of the most iconic tales from the world of plant conservation. Hailed as one of the most successful examples of a species brought back from the brink by botanic gardens’ conservation programmes, it is written about on interpretation boards as far away as the Temperate House at Kew Gardens in London, UK. This beautiful Erica has become a flagship species for biodiversity conservation, brought back from the brink thanks to ex-situ cultivation.

Erica verticillata, also known as the Whorled Heath, was once found on Cape Town’s Cape Flats between the Black River in the north and Tokai in the south. It was found in wetlands in Cape Flats Sand Fynbos, a vegetation type only found in the greater Cape Town area of which just 10% remains. Erica verticillata was extensively harvested for cut flower markets during the 1700 – 1800s. Transformation for agriculture contributed to initial habitat loss, followed by the development of Cape Town’s Southern Suburbs. By the early 1900s Erica verticillata became extinct in the wild and was thought to have been lost forever.

All was not lost however thanks to conservation efforts from botanic gardens. Erica verticillata was first rediscovered growing in a park in Pretoria in 1989 and later other forms were found in other botanic gardens including Kew Gardens and Tresco Abbey Gardens on the Isles of Scilly in the UK. A lone plant was also later identified growing near the braille trail at Kirstenbosch National Botanical Garden by garden foreman Adonis Adonis.

Now there are a total of eight different clones of this species in cultivation, gathered from historical collections from botanical gardens around the world by Kirstenbosch Erica specialist Anthony Hitchcock. These clones have since been used in reintroduction projects in remaining fragments of habitat at Kenilworth Racecourse, Rondevlei and Tokai Park.

Rondebosch Common lies at the heart of Cape Town’s Southern Suburbs and is one of the largest remnants of Cape Flats Sand Fynbos habitat surviving in the City. Volunteer conservation group Friends of Rondebosch Common have been community custodians of Rondebosch Common for more than twenty years, working in partnership with the municipality and other key role players.

Following development of a five-year Restoration Plan, 2019 is the first year of the Rondebosch Common Restoration Project, undertaken in partnership with the City of Cape Town’s Biodiversity and Parks Departments and the Kirstenbosch NBG Conservation Programme. The vision is to actively restore 10% of the degraded habitat on Rondebosch Common, improving its conservation value, habitat structure and biodiversity. This work will include the conservation of many highly threatened plant species through reintroduction and continued alien invasive plant clearing.

This winter the Friends of Rondebosch Common and partners from Kirstenbosch and the City reintroduced the extinct in the wild Erica verticillata to the Rondebosch Common Conservation Area. A hundred individuals of the Whorled Heath were planted in various marginal wetland areas. Five clones were planted in twenty test transects. The data gathered from monitoring these plants will allow us to understand which niche habitats Erica verticillata prefers. This will inform the mass planting planned for 2020.

The reintroduction of Erica verticillata is an exciting step in the conservation of Rondebosch Common and Cape Flats Sand Fynbos habitat. We would like to welcome this beautiful Erica home again.
