Here is a story that will make some oxalis growers in warm climates nervous... I recently went exploring in New South Wales, I often watch road sides & grassy spoon drains for escaped bulbs & I find quite a lot of different species this way, not many that I would have in my garden but now & then I find something really special... I had started between Albery & Mount Beauty Victoria & on a foot path I saw two types of Oxalis flowering, I don't know witch ones, but one had an egg cupped size bluish mauve colour & the other an even larger yellow flower.. Large four leaf clover leaves & very pretty.... So I dug a couple very excited with my find.... They were large ornamental species, not considered invasive & not like the little purple one which is on our noxious weeds list & is irresponsibly passed to gardeners through nursery men who struggle to control it once established... I know this pain because for 12 years I struggled with removing it from a nursery environment & removed enough to make a pile to the moon... Through undying virulence, the help of Ronstar granules, intense spray programs & removal of all contaminated potting mixes, & sterilization of incoming mix, we eventually eradicated it completely over a 6 year period.. As I drove North I saw large yellow oxalis dotted along the road side.... Just one now & then, they didn't look like they were a problem, I arrived in a town before Narrabri from memory & in the middle of town there was a little patch of the same yellows in a small garden & they had spread out onto the foot path, just up the road a few more & then more & as I drove out of town they were scattered along the road side but not that many....soon after conditions improved for them, along the faster highway & the exposed road sides allowed trucks & cars to slip stream the seeds & for the next 100km or more there were thousands & thousands of them spreading along the highway like a giant yellow river... some had spread into the crops & some into the bush, but it was easy to see this is an environmental catastrophe in its early stages..... So the ones I collected went into the fire that night with out any hesitation, but with a little disappointment :-( Steven : ) Esk Queensland Australia Summer Zone 5 Winter Zone 10 On 7 February 2013 03:32, James Waddick <jwaddick@kc.rr.com> wrote: > Dear PBSers, > > I expect abuse about this topic. > > I had avoided growing ANY Oxalis, because of my local weeds and > especially the greenhouse pot weed with pink flowers 9 A sorrel) that comes > up every where, forms bulbs deep in the pot and are a devil to pull out. > > Best Jim W. > > _______________________________________________ > pbs mailing list > pbs@lists.ibiblio.org > http://pacificbulbsociety.org/list.php > http://pacificbulbsociety.org/pbswiki/ > --
