Genus: Oxalis

Oops! I misunderstood - I thought you were referring to the previous question on Asters! Sorry, Oscar.
Right. Oxalis. A completely different genus. There are quite a lot of different types, growing from corms, rhizomes or roots. Some can be invasive - the ones that grow from rhizomes. Most of them are small and don't grow more than a few inches in height. They come in shades of pink but there is a yellow one - O.lobata. Most flower in early summer and keep going into autumn. I recommend O. tetraphylla 'Iron Cross' which is grown from corms space about 4" apart. Its leaves have a distinctive pattern and the flowers are salmon pink. It pops up quite late in the spring but is still going strong now! Some of the little alpine clumpy ones can suffer from rust, and they should be removed and burnt. Hope this helps.

You can get many types and colours of Asters, pink, mauve, purple and white. They also vary in height from dwarf to 4' high, so the spacing depends on which ones you buy. They flower in late summer through into the autumn.

Mine hasn't done so well this year. Sparser leaves and only a few flowers. Last year it was great. also it's friend did not come back. It was either last years drought or last winters freeze I guess.

i would'nt worry too much Chris, they quickly spread into clumps and you can dig them up spring or autumn and divide into more plants.

I bought this earlier in the year, didn't know it had such nice bright flowers, I'll be looking forward to those now!

I've got this one too. I had 2 last year, only 1 left and it's a smaller plant than last year. Not sure whether it's the cold winter or whether they are short lived perennials. I'm happy I've still got 1.

Great name Marguerite, i never realised it but now you come to mention it - it does close up at around four o'clock time. the proper name is Oxalis tetraphylla, and the common names i know for it are 'Lucky Clover' - would imagine because it has four leaves, and 'Iron Cross' - gues that would make sense from the markings in the centre of the leaves. this is just one of many reasons i love this site, you get to find out all the different names people have for things!

Aha, this one I recognise as 4o'clocks. The real name I do not know, but we call them that way as they close up at 4 pm, where they grow ( not here but in the cooler regions ) along the roads and in my garden before.
Beautiful shot of such a small flower. I love that clover leaf with it, such pretty markings, mine were just plain green.

Really like this one Spritz the colour combination compliments.

I have this one also in many parts of my garden and have split to give to friends .

Also planted corms in a container and over th eyears it has filled out and is looking like a pin cushion.

I so like the deep colour of this oxalis .

I have too. They are very reliable, I planted them (little corms) three years ago and they pop up happily each year.

Also known as Iron cross plant I believe. I have it in my garden too.

Thanks (yet again!) Blodyn

Oxalis deppei

Lovely plant I wonder is it as evasive as it's green brother? Hel.xxx.

i don't think so Kev, it is known as the silver shamrock

Lovely.
Is this the one known as Star Of Bethlehem ?

So Pretty :)

I think that's the one that I have - I love its colour, and yes, it is well-behaved! I also have O.'Iron Cross' which are coming up now. They are also good little plants! :-)

I suppose it depends what kind of Oxalis you have! I planted mine straight into the ground at the edge of the border and they come up each year. They are called 'Iron Cross' and they have a distictive dark cross in the middle of each leaf, and coral coloured flowers.

Plant them in a pot about 10cms deep .Keep in shade and don't let them get very dry, but not too wet either!!

Love your oxalis.
