The African Iris is a weed here in Queensland, but there are plenty in gardens. I keep ours as a couple of clumps in the front garden and any seed that sprouts out of the 'clump' area is soon uprooted.
They are so tough - and so lovely when they flower. We inherited them in our yard when we bought 30 years ago. They're still there and have spread a bit - but not actually escaped into the forest. You've shown it beautifully
Beautifully captured and wonderful lighting.
