Ophiopogon planiscapus 'Kokuryu' syn. Ophiopogon planiscapus 'Nigrescens', Ophiopogon planiscapus 'Black Dragon', Ophiopogon planiscapus 'Nigra'

Just one of our absolute favourites, this. It makes a striking contrast to pretty much any colour planting scheme you can imagine.

@gjones yes 100% agreed!

I have one but seems to have reverted to green! Might it be due to light quality? @hilliergardencentres thank you

@leisel could well be they're in a too shady spot - the more sun they get the blacker they go. Also possible (but less likely) is that your soil quality is too good / nutrient rich. These are really a 'treat em mean keep em keen' kind of plant!

Thank you @hilliergardencentres for advice. It was hiding under some marigolds so likely shaded now need to learn to ignore it some more.
