I've been growing this in southwestern (microclimate of zone 4) successfully for 3 years now. It is facing east, and is against a granite wall. I agree...it is very slow growing, but I have offshoots this year! Yay! No slug damage, and lily beetles leave it alone.

This species is green. The cultivars, 'Nigrescens' and 'Arabicus' (which may be two names for the same clone), have black foliage. They are very slow growing, which is why they are so much more expensive than the green.

This is the third summer for my three black mondo grass plants. Two of them have stayed black, bloomed and gone to seed, and maybe doubled in size to a 6" X 12" mound. Last summer the third grew a bit more than the other two and the fresh growth started out green and then darkened. This summer, this one plant is going gangbusters. It has grown to 30" tall and is green. What is up?

I've had several of these growing for a few years in full to light shade. Haven't noticed any flowers yet, but the leaves are great and the plants are beginning to multipy. Another plus is that the rabbits don't seem to like them, unlike the dwarf green mondo salad bar.

I have this grass around the front of my pond. It stands out with all the other grasses I have. It grows better in full sun than shade. It is expensive but I found it at Home Depot and Lowes in the summer in small pots...it multiplies fast. I have not have any insect problems at all. The purple flowers are awesome.

I grow the black, reg. green, dwarf green, and variegated. The black is the slowest and sluggish performer for me. I hoped to have a ring of black mondo around the base of an oak tree and it was so uncooperative, I am now yanking it off and putting clumps here and there in planters hoping it will do better. I guess what bothers me most is that for being the worst performer, it was the priciest.

Even though this plant is a little expensive, it does grow well and spreads within a year or two. I grew them in different areas for a few years, then transplanted them this past fall into one area. I cannot wait to see what happens now! Easy to grow, and fun to mix with others.

We haven't had any slug, insect or disease problems with this plant in the four years we've been growing it. Following are a "gothic garden" built on this plant and my method of propagating it - as mentioned above, it's expensive.

The narrow-leaved, black mondo grass, Ophiopogon planiscapus 'nigrescens', makes eery, low, dark pools that are nice to nestle spooky sculpture in, or run around in streams connecting larger islands like "black flowered" forms of pennisetum, or for underplanting shady woody plants, especially those with sinewy, orange-ish bark (forms of stewartia, paper-barked maple, crepe myrtles come to mind) that echo the red tint in the ophiopogon's black leaves in winter.

There's a smaller, less-likely-to-flop form of white colchicum that could... read more

Has anyone living in an area with Red Lily Leaf Beetle infestation tried to grow this plant? I have wanted to ever since I first saw it about 7 years ago; but it is so expensive I'm afraid to try for fear it will get eaten! (I suspect that if snails and slugs will eat it, the Lily Leaf Beetle will too.) I asked around at several nurseries and no one could give me an answer.

I've only seen this plant at a rare plant nursery in Peachtree City, Georgia, listed as 'Nigrescens,' and I was told it is a slow grower. It was also rather pricey, but a very dramatic looking plant. I have never seen it for sale in any other garden center, but if I ever do, I will certainly buy it, as I now have the perfect climate for it in northcentral Florida, zone 8b.

I'm currently growing Ophiopogon japonicus, the dark green "Mondo Grass" with light lilac flowers that are low and almost hidden among the leaves. Ophiopogon jaburan also has dark green leaves, but more upright white flowers--I'm looking for this one too!

I am able to grow this in my Zone 5A/4B garden on the south side of my home in a protected area. It's great - it multiplies - it flowers - and everyone wants it because it's so unusual around here!

Does well in pots in full sun or half shade provided it is not allowed to dry out. A plant full of interest due to it's unusual, blackish foliage.
