Asleep at the wheel

 

Spring has a way of waking you up like no other season. It brings you outside, don't forget the camera, "oh look over there that one is flowering too". You know the kind of thing. For a gardener it's called excitement.

And so this morning I spent the first hour of daylight wandering around the place capturing the morning glow. So come take a walk with me around our little Marrickville garden — all 7m x 10m of it — and say hello to the first of our spring flowers.


Our Scadoxus patch is steadily increasing in size. I could only fit in nine of the 11 flowers we have, and down at ground level there's another dozen babies doing well. Too small to flower yet, they'll eventually flower at some stage. Not sure when. That's half the fun of growing these things. I barely know what I am doing, but it's working.


This wobbly pano shot shows where the Scadoxus live, under the big old frangipani (that's the ideal place for Pam to hang her forests of Spanish moss that she loves). This is a super shady place in summer but it's well lit in winter once the frangi drops its leaves. To the left of the birdbath those strappy looking things are bromeliads, and they love it here too. I never touch them and they're happily thriving. 

While we're under the frangipani tree, here's another flowering bulb from South Africa (as is the Scadoxus). This is Veltheimia, given to us by our good friends John and Liz, so it always reminds us of them.

The final South African residents happily multiplying under the care of the big old frangipani tree are the yellow clivias. Their flowers should pop out any day now, so the combination of yellow clivia trumpets and dazzling scadoxus fireworks is well worth seeing, and waiting for each year.


Speaking of yellow-flowered people, down the other end of our garden, near the house, the Mardi Gras style blooms of the native Sydney Rock Orchid, Dendrobium kingianum, are in full glory right now. The miracle of this performance is that last year these plants were being attacked by orchid beetles, little chompers that love to dine on unopened flower buds, and so the shows weren't as good as previous years, or this year. These beetles are impossible to control with organic sprays, and I'm not prepared to buy or use the bee-killing commercial sprays (containing Carbaryl) that can control these beetles. So I don't know why the beetles haven't attacked this year but I'm glad they haven't.




I couldn't decide which Nasturtium flower to show you so here's two: there are dozens of them and no two seem to be the same, although they come in all possible combinations of yellow, red and orange, maybe a bit of black trim. Pam and her watercolour art students absolutely adore nasturtiums as a painting subject, and as a gardener I do appreciate the way that nasturtiums suppress other weeds, but they do like to spread out and bully every other plant they come near. I cut them back every few days and they just merrily bounce back without a care in the world. They never complain, they just grow back each time.

We grow our Italian lavender in a pot and it likes it there. There's also a white-flowered type that Pam asked me to get, and it is slower off the mark and probably won't be in flower for another month or so.

One of the hardest flowers to photograph is this thing, a hellebore. That's because the flowers point down to the ground, and I'm too old to take photos lying on my back, so I hold up the flower's foliage with my hand, quickly take a snap and then edit out my finger from the photo. 


I'll finish off with two "panorama" shots of our small inner-city garden, just to give you a bit more context for what I have shown you already. To see the "pano" view, just double click on the photo itself and it will show the much wider shot (hopefully).



This first pano shows the left side of the garden looking out from the back of the house and its covered pergola. 




And this second pano is of the right side of the garden with lots of succulents in pots, more bloody nasturtiums trying to take over. The largish round white pot on the centre right is a native flannel flower bush that flowered beautifully last year and we are hoping will do so again this year too.

Finally, I actually have a couple more blog postings waiting to go. Our front garden is looking lovely but it has not worked out as I had intended, not at all. I'll fill you in on that bit of gardening fun next time.

Easy orchids


Orchids are difficult to grow ... right? Wrong! Some orchids are so easy to grow they barely need any help from me to do their thing. Just a bit of water, an occasional feed of liquid orchid food, and a sheltered spot that gets a bit of sun, but not too much. Mine are nestled up against a side fence, so they get no afternoon sun at all.

And they're flowering now. In preparing to write this little blog posting about my native orchids, I discovered a couple of things I didn't know previously. The first is that they are both closely related, even though one is a tiny little guy with flowers less than one inch wide and the other one is big, bold with "can't miss it" sprays of many yellow blooms. They're both dendrobiums.


This one pictured above is the little person, formal name of Dendrobium kingianum, common name of native rock orchid. Small but perfectly formed ...


And this big yellow personality is Dendrobium speciosum, with a few common names, including rock lily and Sydney rock orchid. But I think of it as the Sydney Mardi Gras orchid.

This is the first time the big yellow orchid has flowered, even though it's been in our garden for the last three years. Now, if I had done my research more thoroughly back then, I would have learned that if you buy a young plant then you are going to have to wait a few years for it to flower. For a while I wondered if I was doing anything wrong, as each year the little rock orchids flowered their heads off and the much bigger plant did nothing. It looked healthy enough, but it just didn't produce flowers. This year was its big debut, and what a spectacular entrance it has made.


I have several pots of the smaller rock orchids, including this white one, and they flower very reliably every year. Two years ago I repotted them all, as they were multiplying quite prolifically and getting overcrowded, and all the transplants have survived the experience.

So, what's the second thing I discovered about these orchids? Well, it seems that these are regarded as two of the easiest native orchids you can grow. Perfect beginner's orchids. And that explains a lot!

I think both forms look wonderful, and the fact they are hardy and do well even in the care of an absolute beginner makes them even more marvellous in my eyes.

Now, I should give credit where credit is due, and mention two Australian websites which are a good source of information on native orchids. One is this page on Angus Stewart's website, and this page at the Australian Orchid Nursery website, which is all about Dendrobium speciosum.

If you are looking for something to grow in a line along a fairly boring fenceline on the western side of your garden, then give orchids a try. Contrary to popular belief, many orchids are not difficult to grow at all. In fact they are remarkably tough, easy-care potted plants. As well as these native dendrobiums, look out for the cymbidium orchids, another excellent choice for beginners.

Buy your orchids already potted up and they should do well in that original pot for the first few years at least. Your local garden centre or major hardware chain will stock special orchid foods. I use a liquid feed that I mix up with water and apply from a can, but there are dry granules which you mix up with water, and slow-release pellets which you scatter around every few months. I find the liquid feed easiest, and I feed my plants whenever I remember to do it. I guess that's about once a month.

All the other stuff about them special potting mixes, etc is true, but it mostly has the effect of making people think orchid growing is difficult. It's not. Just buy a plant already potted up, plonk it in a good spot and you're nine-tenths on your way to success.

Good luck!
