Six summer growing Oxalis species!

This week on The Horti-Culturalists we're taking another look at a group of plants close to Stephen's heart, Oxalis! We made a video about winter growing decorative Oxalis, which you can see here:    • How to grow Oxalis in the garden...do...   and in this video we're looking at their decorative cousins which are summer growing and include some of the most popular house plants of the moment: Oxalis 'Iron Cross' and Oxalis triangularis. Important to note none of the species we look at today are weedy in Australia, although there is one spectacularly weedy winter growing South African Oxalis species in Australia called Oxalis pes-caprae, and we'll learn some very interesting facts about that persistent thug!
There is a lot of confusion about names in the Oxalis world and these are the ones we're looking at today:
Oxalis tetraphylla 'Iron Cross'
Oxalis triangularis
Oxalis regnellii or Oxalis triangularis ssp. papilionacea
Oxalis Stipularis
Oxalis latifolia?
Oxalis magellanica
