About 45 years ago, my parents planted a small clump of Arum italicum in a large wooded area of their central Kentucky yard. Over the years they also planted 30-40 species of native wildflowers that now blanket this grove every spring. For about 30 years, the Arum charmed everyone. Now? Not at all. In fact, A. italicum has become such a menace that in another 20 years none of those native wildflowers will be left. It will be a pure stand of Arum. I've tried digging it out but it's deeply rooted and it's impossible to capture the 100's of small bulbs. Weed-eating hasn't worked. Spraying with Glycophosphate hasn't worked. Our State forester researched the problem and gave me several articles but concluded there was not a known method of killing it. Another commenter mentioned Speedzone: I'll... read more

A beautiful plant that isn't invasive in the Northeast. It IS invasive in the southeast and on the west coast, where it's a threat to the environment. I've grown it in moist garden soil for over ten years, and in that time the clumps have gotten fuller but not much wider. This plant isn't aggressive in my garden, nor in those of any gardeners I know north of Philadelphia. Hardy herbaceous plants with beautiful winter foliage are few and far between.

Be prepared, all the foliage goes summer dormant. Leaves rise up in the fall, stay beautiful through the winter, and more leaves rise up in the spring. Great interplanted with hostas, to timeshare garden space.

The late spring flower spathes are apple green in my garden, attractive but not terribly showy.

I've lived in my little lakeside cottage on the shoreline of Lake Erie in Cleveland, Ohio for 23 years. My yard is very shady and the soil is mostly clay-like. This summer (2012) we have our first Italian Arum stalk (just one) in 15 years. I love this plant and wish it were invasive in my yard. More than one plant every 15 years would be a delight. Does anyone have any suggestions how I might encourage another one of these plants (or more) to grow? Last winter was very mild and those lovely arrowhead-like leaves were present and quite hardy. Do the orange berries drop and reseed another plant? I'm no green thumb, but I'm willing to learn what I need to do to grow more of these cool Italian Arum plants.

I believe this plant came into my garden through horse manure or commercial mushroom compost. I'm convinced it's spreading underground, possibly along the bindweed network that underlies my garden. It has multiplied about a hundred-fold since last year, so this year I've undertaken a zero-tolerance policy and am digging up every blasted corm. I also think that it only takes one cell of this thing to clone itself, although I'm sure I'm missing some of the tiny corms when I remove the big ones, because they attach dirt to themselves and just look like little dirt balls. Nasty stuff! I'm finally realizing that I can't put it into the green bins, because the green bins go to our local composting plant, and I'd just be spreading misery all over town. Do not let this spread any more in Cal... read more

Planted Italian Arum 10 years ago and it is not invasive in Medina, NY. It grows exactly where orignally planted and has gotten larger, but has not invaded its neighbors. It is in part to full shade, and the leaves are green even in the winter, when the snow is moved aside.

Yep, it's invasive! Yep, it's very pretty. Which side of the coin depends on circumstances but you will have been warned if you saw this page. I've enjoyed the plant over the years and never had as much trouble with it as I've had with other invaders-
I've had more invasion issues from it's cousin the Voodoo Lilly, lamium galeobdolon luteum, viola odorata, hypericum (not sure which I have but it's taking over) to name a few culprits. I seem to have managed to inherit a swelling army of notorious invaders over the years. It would be funny if it wasn't such a drag.
I have liked italian arum for giving a lush tropical look to dry shade but wouldn't plant voluntarily it if I was concerned about escapes or inundation. [Sonoma CA]

I tried for 7 or 8 years to eradicate this beautiful, but invasive plant, but it thrived and spread where it had not grown before. I sifted soil, removing what bulbs I could see. I burned emerging shoots methodically. I tried many sprays. Finally a commercial gardener suggested SpeedZone. I have used this two years and now am winning the battle. I have allowed only one patch of Arum italicum in our yard because my wife likes it for flower arrangements. This patch is surrounded by concrete and cannot escape. And I do not allow the seeds to escape. I cut them down during the summer after the leaves have died back. New leaves emerge in the fall or winter to repeat the cycle. If you do want to grow them, plant them in stainless steel or concrete and don't allow them to escape. Put a warning on... read more

We live in Arkansas where this corm was already planted in one spot in the yard by the previous homeowners. At first we liked it, as it was the only planted plant that was green even on the coldest winter days. Last year I decided I didn't want to let the green-turning-red corn cob-like seed heads to replant themselves, so I cut them off with pruning sheers. OUCH! My skin started prickling and itching and the effects lasted over an hour or more. One of the reviewers said this was the chemical, calcium oxylate. Interesting. I would be worried about children getting their hands on these alluring seed heads. I decided I didn't want this plant in the yard, so when the leaves reappeared in the autumn, I sprayed them with RoundUp, but they resprouted some months later. So, now it is lat... read more

We are in Ohio and I'm curious about this plant. After buying our first house we're finding all sorts of volunteer plants in our yard from muscari, to daffodils, the morning glories that have taken over the side of the yard, three types of ivy, to the balding cypress that my husband thought was dead until it suddenly sprouted green, to the myriad of rose bushes that had been hacked down and are trying to grow again to this plant that took us forever to identify.

I think it's neat looking and I want more of a green yard that I don't have to fuss too much with. Right now it's taken up residence along our back fence and seems pretty tame.

When we moved to this property about 18 years ago, Arum appeared in a few places and I thought it was nice to have green sprouting in late winter. Now it's multiplying on a grand scale. I,m now removing all seed heads before they turn orange. I've tried digging, but can never get all the baby corms. Tried Roundup which will kill the leaves if the weather stays dry enough, but the next year's growth seems just as strong. I just read a suggestion on another site about adding detergent and liquid fertilizer to the Round up which I may try this year. Anyone with a certain method for removal, please post it. FYI:This is on the invasive list for Oregon.

I have several of these growing in a bed with geraniums, roses, calla lilies and naked ladies. There are a few more in my backyard under a meyer lemon tree. I haven't had any problems with it being invasive - the geraniums are far worse in that regard. I almost never water it and the ones in the geranium bed get full sun all summer long. The one under the lemon tree gets more shade, water and even Miracle-Gro but it hasn't spread much either. I don't know if it's the hot, dry summers or something in the soil but I don't seem to have the same problems with this plant that plague my fellow CA gardeners.

Good grief. My neighbor told me about this little-shop-of-horrors of a plant a few years ago, encouraging me to dig it up and dispose of it immediately if I ever saw it. Had I heeded his warning then, I would not be dealing with the mass infestation I have now. This afternoon I decided to start getting rid of it in earnest.

Add me to the list of disgruntled CA gardeners with this cuckoo of an arum.

At least it's more enjoyable to those in other parts of the country. Maybe I'll list it for trade...hmmm.

I am going to try this plant in Firestone, Colorado. Last winter we visited the Denver Botanical Garden specifically to see what was green in winter. We found Arum Italicum with beautiful green leaves and the full clusters of orange-red berries just beautiful. I believe DBG is in Zone 5, as are we. Will post again with what success (or not) that we have with it here. I doubt that I have to worry about its invasiveness in this zone.

It sounds like this plant should be avoided in the warmer zones. Here in zone 6 it behaves quite nicely. It stays in a clump and multiplies slowly like any plant would. Of course, I'm growing it under a pine tree and a maple tree and in pure clay soil, so the conditions are far from ideal. Maybe its robust nature helps it thrive where other plants have suffered. I love the stalks of berries in summer and the foliage in winter. I don't mind it going dormant in the summer because I'd rather have the foliage in the winter anyway!

Avoid at any cost!! Ever since moving to my present home on 2 1/2 acres 18 years ago, I have watched Arum italicum extend its coverage, displacing even crabgrass. This is in spite of all the hours I have spent each spring chopping down every single blossom and disposing of every single seed pod I could find. It flourishs in under the big oaks and grows to a couple of feet high in the spring. The leaf petioles and blades are semi-succulent and are filled with tiny crystals of calcium oxylate, visible in a high-power microscope. The calcium oxylate effectively deters any insect or other herbivore from eating the plants and, if you handle them, will make the skin between your fingers itch, much like fiberglas. YOU HAVE BEEN WARNED! DO NOT SPREAD THIS PEST!!

A good companion for hostas; when the hostas die back in the fall, Arum will produce leaves repeating the shape of the dormant hostas, and remain green all winter. Plants produce white spathes of flowers in late spring, then go dormant as the hostas re-emerge. The berries form after the flowering is completed, and remain to provide late spring interest.
