Thank you to Mary Sue for helping me identify the oxalis that I saw escaped
for 100km in New south wales here in Australia, it is Oxalis pes-caprae ,
it must be spectacular in its native environment....

If I could only grow New Zealand Yams like that...... Yummy tubers !!!!
That's a cool oxalis !!!!!
