What’s flowering – Gladiolus vaginatus

I am always amazed to find such delicate flowers such as this Gladiolus vaginatus in full flower at the driest time of the year. The earth is powdery dry and we have barely had any rain for months. Gladiolus vaginatus is flowering at the moment in the Walker Bay region. In our part of the world it is restricted to limestone but also grows in clay-loam (renosterveld) and has a natural distribution from the Cape Peninsula to Knysna. In the latest Red List of South African plants it is classified as vulnerable on the basis that it has lost much of its habitat and has become severly fragmented as a result of crop cultivation, coastal development and alien invasive plants.

Whats flowering – Gladiolus brevifolius

Gladiolus brevifolius (March pypie, Autumn pipes) is a late summer/autumn flowering Gladiolus that grows on sandstone and shale slopes from Clanwilliam to Riviersonderend and Bredasdorp. It flowers in 8- to 12-flowered pink spikes with yellow markings. A solitary, sword-shaped  leaf with thickened margins is produced after fire. Of the approximately 260 species of Gladiolus in the world, 165 grow in southern Africa and 110 are found in the Cape. Many amongst this spectacular group of plants have horticultural value.

Fire Diary – Week 5 (7 March)

One of the fastest growing species after fire that I have come across is Asparagus rubicundus (wild asparagus, katdoring). The photo below was taken just one month after fire showing the amazing growth of this resprouting species.

Not only had this individual grown more than 1.2 m in a month but a close up of the plant reveals that it was already in full flower.

Colour for your fynbos garden during dry season

I am often asked to help design gardens that will have colour and flowers throughout the year. With the abundance of Cape species that flower in autumn, winter and spring these months are not difficult to cover. However, late summer can be a challenge and two of my favourites are Tecoma capensis (Cape honeysuckle) and Plumbago auriculata (plumbago, syselbos). These are both hardy, local indigenous species that grow quickly, attract birds to the garden and flower well in late summer. I took this picture yesterday in the Grootbos gardens of a apricot flowered Tecoma (you also get them in red, yellow and pink) and a blue Plumbago (darker blue and white are also available). Planted together these two can provide a great natural screen against a wall or fence and add some much needed colour to a fynbos garden during the dry, late summer months.

Neither are indigenous to the Western Cape with Tecoma capensis growing naturally from Uitenhage in the Eastern Cape to southern Mozambique, while Plumbago auriculata flowers from December to May and grows naturally from George to Mpumalanga.

What’s flowering – Amaryllis belladonna

When I first moved into the Uilkraals Valley I was amazed to find so many Amaryllis belladonna (March lily) flowering all over the valley. I had never seen this species flowering on Grootbos or in the Walker Bay region (which is just over the hill), yet it is a common site to see fields of this beauty during late February and March in our valley. At first I thought it was an escapee from gardens, as I observed most of them around old farm houses, but I have subsequently found many growing naturally in the wilds. I was out walking my dogs yesterday when I came across this field of Amaryllis.

A close up reveals the beauty of this wonderous plant that, like other members of the Amaryllis family, flowers at the driest time of the year. It has a narcissus-scented pink flower and grows in loamy to sandy soils in the lowlands of the South western Cape.

Fire Diary – Week 4 (28 February)

Haemanthus sanguineus emerging after fire in fynbos

In the fourth week following the fire Heiner took some great photos. The bright red flowers of Haemanthus and Brunsvigia were appearing all over the landscape. Many of these plants had been smothered by old, dense fynbos prior to the fire and were making there first flowering appearance in many years. below is great shot of a single Haemanthus sanguineus appearing at the base of huge burnt out Leucadendron coniferum (dune conebush) skeletons.

In open sandy areas we came across groups of Haemanthus at sites where we had never before seen them.

A day of botanising at Salmonsdam Nature Reserve

Today I accompanied our new intake of twelve Green Futures students to Salmonsdam Nature Reserve near Stanford on the Agulhas Plain. The beautiful little nature reserve is tucked away off the beaten track and not very well known by visitors to the region. It has always been a family favourite and was the place I learnt to swim in the brown waters of the old swimming trough at the bottom of the campsite. It really hasn’t changed in the last thirty years and I think that is part of its charm and one of the reasons it remains one of my favourite places. There are some wonderful walks, 4X4 and mountain biking routes on the Reserve. We took a short walk to the waterfall and I was able to show the students a lot of different plants, fynbos, wetland and forest vegetation and explain lots of cool eco-stories. They loved it and it was great to see their enthusiasm and interest once we got out of the classroom and touched, smelt and experienced our beautiful flora first hand. We even pulled out a few alien plants, spotted an awesome mole snake (see photos below) and ended the trip with a boerewors braai and some singing, dancing and football.
Below are a couple of our discoveries from Salmonsdam.

Leucadendron salignum at Salmonsdam

This is a very beautiful red form of Leucadendron salignum (geelbos, common sunshine conebush). It’s a multi-stemmed shrub that is able to resprout after fire from a woody rootstock. This is the most widespread member of the Protea family in the fynbos, occuring from the Bokkeveld Escarpment to the Cape Peninsula and eastwards to the Eastern Cape. This species is characterised by its wide colour variation of leaves and bracts. In our area most are yellowish-green so it was great to see this vivid orange-red population at Salmonsdam today. The well known hybrid Safari Sunset with its bright red leaves and bracts is a cross between Leucadendron salignum and Leucadendrom laureolum and is a popular export flower in many parts of the world.

This beauty is Erica longiaristata (pinkies) in full flower in Salmonsdam Nature Reserve. This species has a narrow distribution range growing on the mountains from Hermanus, Baardskeedersbos to Elim and Napier.

Mole snake at Salmonsdam Nature Reserve

This chap is of the mole snake (Pseudaspis cana) that we discovered at the camp site on returning from our walk. This species of snake is common in sandy soils in the fynbos where it enjoys tucking into the local mole rat populations. It can grow to up to 2m long and is non-venomous although it can give a good bite if it gets a chance. In mature individuals the body is mostly one color. In our area and most of its southern range it is black like this specimen but can also vary from yellow to brown to grey. The young have dark markings and spots that are gradually lost as the individual ages.
While I could see that the students were very nervous it was a great opportunity to show them that these snakes will always move off if given a chance and are really harmless to humans and an important part of the ecology.

Whats flowering – Disa uniflora

Disa uniflora from Kleinjoostenberg nurseryDisa uniflora from Kelinjoostenberg nursery

Ok, so here is a bit of a cheaky one but I cant help but put this beauty up for all to enjoy. As a staunch Western Province rugby supporter the red disa has always been one of my favourite flowers and is always worth the trek up Table Mountain or Fernkloof in Hermanus at this time of the year. It grows on wet cliffs and along streamsides and seeps from the Cederberg Mountains to Betty’s Bay and the Riviersonderend Mountains.

This year I found it at one of my favourite fynbos nurseries, Van den Berg Nursery at Kleinjoostenberg on the R304. This nursery is well worth a visit if you live in the Cape Town region and are looking for a wide range of reasonably priced indigenous plants.

Fire Diary – Week 3 (21 February)

Three weeks after the fire and despite no rain there is lots of growth amongst the resprouters. Relatively few fynbos species are resprouters, regenerating by sprouting from their burnt out stumps after fire. The vast majority of fynbos plants are seeders, (or reseeders) that are killed by fire and only germinate from seed after fire. The resprouters are able to survive fire and resprout from a woody rootstock. They are able to regrow more rapidly than reseeders, using their reserves stored underground. Below are two examples of resprouters that were grwoing at an amazing pace just three weeks after the fire and with no rain. The first is Asparagus rubicundus (wild asparagus) which becomes particularly prickly as it matures and has left many a hiker with horribly scratched shins.

What’s flowering – Cyrtanthus leucanthus

Cyrtanthus leucanthus or the witbergpypie (white mountain pipe) is flowering at the moment in Walker Bay. This is an endangered species and local endemic that is restricted to the area between Betty’s Bay and Potberg and grows on limestone and sandstone soils. It has a hollow flowering stem and bears up to three pale cream, scented flowers that are about 40 mm long. The leaves only appear once flowering is completed. Continue reading
