Mostly Green Sunday Flower Walk

Although the burned veld looks grey from a distance, now after seven weeks, the colour is returning, although it's mostly green leaves. Here and there a splash of colour is visible from a distance, like this Tritoniopsis, in a crack in the rock which escaped the worst of the fire, Possibly T. antholyza. It looks as if we're in for a good showing of them in the next few weeks, judging from the leaves coming up.

Jennetta wrote in for more details of the Buchu Agathosma we have been watching. We have assumed it's A. betulina, but she's wondering whether it could be A. crelulata ?

Agathosma, but betulina or crenulata?

Some of the guide books don't show the leaves, which apparently distinguish them. Here is a close-up of them. Comments, please! However, there's no mistaking the Buchu aroma! We are also watching its babies growing all around it, getting bigger by the year!

The re-growth of the Lanaria lanata has reached about 400mm in most places, and the leaves are beginning to hang down. Here the tips are describing arcs in the bare sand.

One would expect a shrub like this to be very dead after suffering a 'hot' fire like this, but Fynbos is resilient! Not sure yet what this is:

We went to see the large Leucospermum oleifolium we found just before the fire.

Close inspection of the spent flowers shows there might be life in the seeds yet!

Here, a Liparia splendens which was burned, is shooting from its base:

..... and another, we remember that's what was growing here, formerly within the forest, now it'll be in full sun. This one was totally burned-off:

Amazingly, there are still a few seeds to distribute from this Protea cynaroides!

Pink Oxalis are to be seen here and there, and more to come, judging from the clover-lile leaves to be seen all over.

The Fire Asparagus, Asparagus lignosus isn't growing as fast as it did in the first few weeks, but it makes a pretty plant with its little white flowers (and sharp thorns!).
Recovering Agapanthus walshii:

We counted 24 flowers on these Agapanthus walshii before the fire

Had we not packed rocks around this plant, the two bicycles might well have ridden right over them! Can't they stick to the tracks?

Back in the Village, outside Grabouw Auto Electrical, the Silk Floss Tree Ceiba speciosa (formerly Chorisia speciosa). For some reason only a high branch is flowering this year.

Apparently the seeds were imported in the stuffing of a pillow from South America many years ago and planted in Rondebosch, and grew! Related to the Baobab and Kapok Tree, I read. You only lean on this trunk once!

Sharp spines on the Silk Floss Tree trunk!

Last weekend I visited the Eastern Freestate, where one comes across different plants. Here on the farm, a field of Cosmos, which is much darker than the roadside specimens, is the result of selective breeding:

Deep pink Cosmos as far as you can see!

More Cosmos!

Every day we went out on a Military Vehicle convoy near the Lesotho border....

Very different terrain in the Eastern Freestate!

and on the stops, we were able to observe what was growing next to the track:

Unknown flower on the side of the track

Any guesses?

This is what the plant looks like

Another, there were several more unfamiliar plants:

Glossy leaves and a tall flower head

Shiny leaves above and spent flowers below:

Fire Asparagus Sunday Flower Walk

It is now 4½ weeks since the fire and we were today discussing the plants which have recovered, in order of their appearance.
Within days the Fire Lilies Cyrtanthus ventricosa were up, and at the same time the green shoots of Lanaria lanata were pushing up their burned ends. Various grasses were quick to follow. We were happy to see the Agapanthus walshii shooting from burned stumps. Then we found the Fire Asparagus Asparagus lignosus and it's all over! Recognisable by the dense light green splash it makes on the burned background, it's standing out and the earliest are now in flower:

Asparagus lignosus flowers and leaves

The flowers are tiny, the leaves firm, almost like short pine-needles and the thorns in the axils needle sharp!

Asparagus lignosus branch

What is surprising is that it seems to have been there all the time and we've never noticed them! Look at the base of this one; there are plenty of burned-off stems. The 'woodiness' of the name 'lignosus' is apparent here:

This is what the whole plant looks like in the bleak landscape:

I mentioned the Agapanthus walshii, we have been watching them for years now and know where to find them. But what is very satisfying is to see others in their vicinity now shooting, which we were unaware of.

Agapanthus walshii

They are very rare; in SANBI's Red List, they are EN B1ab(ii,iii); C1

"Known from a restricted range (35 km²) in the Elgin valley, recorded from less than five locations with continuing decline of the largest subpopulation occurring as a result of informal settlement expansion."
It's pleasing to know that they will have survived the fire. It took some looking to find a bunch we have been keeping an eye on for years. We knew where to look and knew that it should be sprouting. The fire must have been very 'hot' there, but today we found it and packed stones around to make it easier it find in future. There were five flowers on it when the fire came through, including one which we had put a stocking over, to catch a few seeds.

Agapanthus walshii, an old stand, recovering

Elsewhere, they're thriving!

More Agapanthus walshii

The Pelargoniums are recovering fast in places, some straight out of the ground:

..... and some from the bases of burned bushes:

This shows the stage that Lanaria lanata has reached so far, this one recognisable by the remains of flowers:

Lanaria lanata with the remains of flowers

All over, the Palmiet is pushing out green shoots, not only from the burned stems, but from the base too:

Palmiet, shooting

So far this is the only Fire Lily Cyrtanthus ventricosa we have found which has set seed. The leaves are showing, but from our observations, they don't get much bigger than this:

Fire Lily Cyrtanthus ventricosa with seed pod

One side of the pod is open, we're not sure whether it has been eaten or that it's beginning to split open to distribute seeds.

Seed pod of Fire Lily Cyrtanthius ventricosa

To give an idea of how 'hot' the fire was and how deep it burned, this dog lead is 1.2 metres long and its clip is just touching the bottom of the hole left from a pine root! If that plant on top survives, it's hardy!

Root of pine burned to a depth of more than one metre!

Here, Lanaria lanata is giving the otherwise bleak background a green hue:

It made a change to get back into the unburned section and to find old favourites like this White Water Alder Brachylaena neriifolia, still in flower, as the others would be!

.... and our old favourite, the Many Umbrellas Heath Erica multumbellifera:

This is how it grows, many of the flowers are spent:

At the dam on the Experimental Farm next door, we were treated to the sight of six Spoonbills. We seldom see more than one at a time. Here they are amongst Sacred Ibis, Blacksmith Plovers (oops! Lapwings) and a Darter:

We watched the large flock of Sacred Ibis land, then just four Hadeda Ibis took off from the bank of the dam on the left with their raucous calls, causing all the birds on the island to fly away, the Spoonbills keeping to themselves in flight, and returning first. What made the Hadeda's fly off? Not sure, but looking up we saw a Fish Eagle circling! Quite a performance for us in a minute or so!

Late, short Sunday Flower Walk

We were in Cape Town today for Mother's 93rd Birthday Party and got back late. Not wishing to disappoint you all, we went up into 'our' patch to monitor the re-growth after the fire, which was now 3½ weeks ago.
Last week we featured a bush which had grown phenomenally in 2½ weeks, and Pat and Jennetta both kindly identified it as Fire Asparagus Asparagus lignosus. Tony Rebelo, who has in this last week patiently guided me through the process of loading observations on iSpot, agrees http://www.ispotnature.org/node/651088
Today we found another, even bigger:

Pippa shows how big this Fire Asparagus Asparagus lignosus has grown 

Pippa gives an idea of the size; the stems are a metre long already! At each node is a very sharp thorn and the shoot grows from the axil. (Hands still covered in Steenvas from yesterday at Mostert's Mill, despite much scrubbing! see http://compagnesdriftmill.blogspot.com/)

Growing tip and buds of Asparagus lignosus

Close by was the remains of a Bobartia (I wouldn't dare guess which!). It seems to have survived the fire  well.

Bobartia after the fire

.... and it looks as if the seeds could be ready to be dispersed.

We never realised there were so many, but this is but one of many Lanaria lanata (thanks Pat for the confirmation). They shot up quickly after the fire, the green is now mostly 200 to 300mm tall, and the rapid growth seems to have slowed.

Lanaria lanata

This looks like a Daisy, the one we think is a Euryops, shooting from the base already.

Euryops (?) regrowth from the base

We went to where we knew many Watsonia schlechteri were growing, and we weren't disappointed.

This tortoise didn't make it :-(

We went back to where we found another 'new' plant last week:

Tulbaghia alliacea

Again, both Pat and Jennetta suggested Tulbaghia alliacea. Yes, I nibbled a leaf, and I'm still burping garlic! I still couldn't freeze the flowers!

Tulbaghia alliacea flowers

We went on to where Pippa was sketching new-found Agapanthus walshii a couple of months ago, to find them also recovering: 

Agapanthus walshii

On our way home we found the remains of a burned Brachylaena neriifolia which we could recognise by the flowers.

Here again, there is re-growth from the base already:

It will be interesting to see how the new growth takes over the old.

There should be a New Moon out there somewhere!

Sunset!
