FAQ
Questions, answered
Is Irish moss a real moss?
No. It's a low flowering perennial that looks like moss, which is why it tolerates sun.
Can I return opened seeds?
No. Once opened, seeds can't be refunded or exchanged.
Indoors or outdoors?
Start indoors for best germination, then plant out in a constantly moist area.
