Why are you growing weeds? I was a bit taken a back because as far as I knew Senecio lautus was an Australian Native daisy. So what is a definition of a weed?
My understanding is that weeds:
- are introduced species from another continent, usually brought in by people knowingly or unknowingly eg. in the padding in saddles in the ‘olden days’.
- are introduced species which have become escapees from garden environments eg. watsonias and Acacia baileyana in the Adelaide Hills
- native species planted for a specific purpose which have escaped that particular environment
- native species which seed all over the place and take over garden beds. Some people don’t mind this but to others it is a nuisance and the plant is therefore a weed.
Senecio lautus may come into the latter category, but I don’t mind at all. Bring it on, I say. They flower among the mallee trees on our block, come up in pots where I don’t want them, flower prolifically along the South Eastern Freeway on the way to Adelaide and give a glorious glow of warmth on cold cloudy days.
They are easily pulled out if not wanted in a specific location. Some appear to be perennial up to 60-70cm tall, others flower at about 30cm, some require cutting back after flowering to maintain a neat bush. Many just appear to die back and re-shoot when it rains in early winter. I consider them worth having, but of course once you have one seed in the garden you are likely to have them next season whether you want them or not! Find out more about Senecio lautus.
I picked some yesterday morning in an experiment to see if they would last as a cut flower. I hadn’t bothered to try before. I will report back. One thing I did notice is that some flowers closed their petals last night.
When I look at the date on the last post made on this blog I am horrified but that is how life is sometimes. I have had to desist growing the large numbers of plants I used to but I cannot resist plants that have cuttings on them so I am always having a go at something, just not on the scale I would like to do.
A friend asked me for photos of a couple of South Australian native plants and that set me thinking about what I might be able to do on the blog. There are a number of posts that need tidying where links have been broken over the years, and probably better photos in my collection now. Spring is a great time to be stimulated to share the wonder of our amazing native plants as many begin to burst into flower in the next few months.
For further information Olearia pannosa.
Olearia passerinoides is a mallee daisy and is quite a large bush with bright green leaves, different to many mallee daisies which often have grey green leaves. Although this is a shrub, to me it behaves as a perennial shrub, in that new growth appears along the older wood.
The bush has a tendency to become scruffy, with the leaves higher up the stems and the flowers also high. If it was cut back to the lower growths, it would have dense foliage and be a more compact plant, and I suspect the flowering would also be quite spectacular.
As usual, I promise myself that I will do this, and yet another season goes buy. Mine have just finished flowering, so out with the secateurs tomorrow, while I think of it.
Olearia passerinoides is drought, lime and frost tolerant. It has clusters of small white daisies and grows to 2-3m tall by about 1.5-2m wide if left to its own devices. Pruning will keep it to a more compact size.
Calocephalus lacteus is a small spreading plant with small, globular, whitish flower heads in late spring and summer. The photo was taken in early January in Canberra Botanic Gardens.
The plant suckers, growing 10-30 cm tall by 1-1.5 metres wide. It is hardy in most situations, prefers moist soil but withstands periods of dryness. It grows in full sun to part shade in sand loam or clay that is well drained. It would need some water during the summer in low rainfall areas.
Calocephalus citreus is a small member of the daisy family, growing 20-50 cm high by 30-60 cm wide. It has silver grey foliage and small, yellow button type flowerheads in late Spring to Summer. The photo was taken in early January at Canberra Botanic Gardens.
This plant is perennial and should be pruned after flowering when new growths begin near the base of the plant. It is hardy in most situations and withstands dry periods.
I would call it a drought tolerant plant when I observe its survival here. It grows in loam and sand, in half to full sun, including dappled sun.
This attractive daisy dries well for use in flower arrangements.
