Some of these are a fair few years old now. But well worth the time and effort to grow on to maturity.
Totally agree, it's not always about a name. Number 3 looks very much like Fairy Hair. Is it a seedling from Scolopendrifolium ?
I have Scolopendrifolium, so it’s a possibility. Most of these have just been rescued after self sowing and grown on, some are still where they self seeded, if they do well, I would say it’s down to them sprouting in the ideal place, usually well tucked away with good shade.
