I was out for a dander near the coast recently and found some soapwort. Now this one is a little different than the one I've seen before so I'm assuming it's a garden escapee. Nonetheless it was quite prolific and pretty to look at
Same leaf configuration I've seen before but the petals are a little different, however I took some back to see if it had saponins that could lather in soft water..
I crushed the leaves, gave it a little rub between my hands and it lathered up very well.. A handy find.
