Buyers watch out for cheats! For some reason garden centres and nurseries all over the world sell Gunnera Tinctoria under the label of G...Read Moreunnera Manicata. I was cheated this way in Leroy Merlin (will never buy there again). G. Tinctoria is twice smaller than G. Manicata. It's leaves are not as profound in shapes, nor is its overall habit.

I have maintained this plant in a roll-around wine barrel planter. It thrived for 2 months in Spring. Since then it has seemed rather u...Read Morenhappy in various degrees of sun and shade over the past year. It didn't do well in my greenhouse either. It has grown stalks with platter size leaves that eventually begin dying. I now planted it in a bathtub planter against a fence. I plan to keep it very moist and fed with weak fish emulsion over the winter and after. I read that one can cover the corm with old leaves to protect it from frost in winter. I plan to try this, but don't know if I am supposed to cut the stalks off at the corm or just cut the leaves....HELP

I have purchased a rhizome of Great gunnera but I'm not sure how to plant it (on its side or up and down) and how deep to plant it. Need...Read More some help, please.

This plant grows easily and profusely with little attention in Swansea, Wales where the climate is mild and damp most of the year. In SE ...Read MorePennsylvania it needs more attention. I failed twice by duplicating the growing location I had seen in Clyne Park in Swansea (damp area in partial shade) and at RHS Wisley (damp area in full sun). A few years ago I was in Amsterdam botanical garden where they were very proud of having finally grown a large stand of this plant. The winters in the Netherlands are cold and damp. Their technique was to grow it at the side of an ornamental pool with continuous moisture in the summer but in the winter they drop the water level and mulch heavily. I do not have a pond but instead of planting at the damp foot of a slope I have moved in up a few feet to dry ground. In the winter I leave it dry and mulch the crown the same way as for Musa basjoo. In the spring I uncover and begin watering offering crown protection if a hard frost is forecast. The drawback is the need for heavy summer watering but thus far it is through 3 winters and slowly gaining in size.

Not giving up, giving in for I'm going to try it again!

2005 I ordered 'great gunnera' from eBurgess's catalog. The ad. s...Read Morehowed an amazing large, exotic looking shrubby plant for folliage. It's listed for zone 7-8, and I live right in the midle of this 2 zones. Well, I failed. First I tried in a Big pot with lots of water; (this time the bulb was quite big; that of a big elephant-ear tuber) the young leaves sprouted, but promptly turned black and withered. So, I rescued to a boggy area, and the bulb-like Great Gunnera was GREAT no longer: it rotted. Now that the grievant process of its loss is subsided. I decided that it's time to try this again. Yesterday my 'bulb' arrived from Inter-State-Nurseries the size is small about that of large egg. I'll keep the bulb/tuber in the dard and do more research before I plant this 'little, big gunnera.

Even thou...Read Moregh this plant thrives off of super moist soil, I heard from a local nursery that it does fine in moderately dry well drained soil as well. Does anybody out there have any experiences to back that up?

I'm extremely excited about my new Gunnera. I just don't know why it's leaves are turning brown. I bought it 3 weeks ago with a tiny leaf...Read More and now it's growing quickly but the biggest leaf is dying as is the one in the picture I posted. The tiny new leaf also has brown/black dry edges. What am I doing wrong?

I have it in potting soil which one site said is a no-no. They said it'll make the roots rot but most of you seem to say the more water the better. Any suggestions???
PS. It quadrupled in size in 1 week. It's a fun plant!

Despite what the label might say, most of the plants offered as G. manicata in the U.S. turn out to be G. tinctoria. The second photo fr...Read Moreom the top submitted by arsenic shows the inflorescence of true G. manicata. Compare it to the inflorescence picture by KMAC which is of G. tinctoria. Note that the inflorescence branches of manicata are longer, thinner and stay green, whereas those of G. tinctoria are shorter and thicker and take on a rusty brown hue.

I saw this plant in Harrogate, Yorkshire, UK, growing alongside streams and other bodies of water. It was HUGE--some of the clumps must ...Read Morehave been 8 feet high by 12 feet across!

Hi. Pictures of this plan have always fascinated me, so after a lot of searching, I found one. I planted it on the northwest corner of th...Read Moree house in a bed... not near water. It is now October and it has grown to about 5' tall. It has long stems and the leaves are about as big as a meat platter. It probably would have done a lot more for me, but I really forgot about it (I have so much stuff!!). It has grown in the back of the bed, and it looks pretty happy, but it just is not big. I am going to dig it up and bring it inside, I guess, for the winter. Does anyone have a better idea for it? Do you think if I just mulch it it will be okay? I'd rather leave it outside if it will not die.

Thanks for any comments you might have for me.

I live in Oregon and was given one of these awesome plants as a gift. I have no problems with it as long as I give it LOTS of water. Th...Read Moree friend who gave it to me told me to take the cone off before the 1st freeze, put it in a pot with potting soil and let it sit over the winter. By spring I should have new plants. This however, did not work for me. Anyone know if this is accurate and what I may have done wrong? My poor cousin is dying for a start! :) Thanks.

We recently rescued a Gunnera that had been on a hillside without enough water for several years. Before that it had been lovingly watere...Read Mored and pampered by the previous owner for almost 10 years. The corm had 5 arms and was approximately 4 feet from tip to tip. We had to chop it into 6 sections to remove. The largest took two people to lift. The smallest was a little smaller than a bowling ball.

Right now all the pieces are planted alongside our creek at varying levels of moisture. We are hoping most of the pieces survive and shade the water to make it more hospitable for the salmon smolts. If they do well we're going to have the coolest looking swamp in Columbia County.

It moved from Vanouver Wash, to Scappoose Oregon.

There are superb specimens at RHS Wisley (UK)

Amazing growth never seems to stop. I cut everything down at first freeze and mulch with its leaves and those giant flower pods. Does anyone know any practical uses for this plant? Any hazards?

I hate to say my experience was all positive with this plant since I simply can't grow it here in the heat of So Cal... but if babied alo...Read Moreng and kept moist, it does survive here. However I love this plant. It can be massive. I saw one in Vancouver that was way over my head. It has very rough and scratchy leaves that can almost take your skin off. Not a plant for a small garden, either. But impressive when done right.

I saw gunnera leaves being used to wrap and cook food in Guatemala. Apparently the leaves are not toxic, but they are not really palatable.

I started growing Giant gunneras a few years ago. The original soil was potting soil and fairly dry... The plant never did well in th...Read Moree ground or in a pot... Did a little reseach and found that the plant lives natively in a bog setting. Since the plant is a tuber, much like a rhubarb, I "tore" off a chunk of root and planted in in a pot with a mixture of50% peat and 50% potting soil. Placed the 2 gallon pot with soil and root into a fish pond so that the bottom six inches of the pot was submerged and let it go... The plant went crazy!! Shot up giant leaves like it was going out of style! Happiest little gunnera on the block. ;)
