Cleveland Gunnera Survived Winter.

Well I went out last week while the weather was still nice (we had over a foot of snow this weekend)and uncovered several of my VERY marginal plants to see if they survived.

The Gunnera manicata that I bought from the local pond store survived with flying colors surviving a week of below zero weather protected by it's own leaves that I cut off and laid on top of the crowns and a layer of leaves.

A little bit of background, the plant is located at the north side of the house planted against the wall. I'll keep you posted on how it does throughout the season.

RE: Cleveland Gunnera Survived Winter with picture

Well, Easter weekend was a bit dicey, We had temperatures in the upper 20s and a lot of things were frozen. The Gunnera fared really well!

Additionally I had a number of non-bog plants that shouldn't have survived come back including a ginger (Zingiber mioga), two bananas (basjoo and Musella lasiocarpa), Chilean bellflower (Lapageria rosea), and a couple of oddball southern hemisphere conifers...I'm a real happy camper this season!

RE: Cleveland Gunnera Survived Winter.

Good going!! I saw some of these growing wild in Costa Rica only at high altitude of course and in seep areas. I've killed a few of these lol They can't take the Florida heat did great during the winter though. The one cool grower that I would reaally like to grow.
How do they do during your summers?? gary

RE: Cleveland Gunnera Survived Winter.

What southern hemisphere conifers survived for you, and what did they have for protection?

RE: Cleveland Gunnera Survived Winter.

the only southern hemisphere conifer that I had out this winter was Podocarpus nivalis. got to -6 and only snowcover for protection.

I put out Cunninghamia lanceolata which survived but oddly enough the area of the tree that were protected under the snow were the areas with dieback. the top of the plant was fine!

RE: Cleveland Gunnera Survived Winter.

How did you do this winter?
Where were those other non-bog plants? Were they, especially the lapageria, near enough to the house to get some warmth?

RE: Cleveland Gunnera Survived Winter.

It does not appear that the location of the Gunnera is too wet, can you describe the conditions of wher it is planted?
I killed one last year because I kept it too wet. I just got a second on and would like to keep it alive. I have a green house so a container would be ok .

RE: Cleveland Gunnera Survived Winter.

Sorry for the delay in responding.

The Gunnera is on the north side of the house next to the foundation. When the leaves are killed in fall I cut them off and lay them over the crown.

I grow Gunnera just like I do Rhubarb with the exception that I plant it close to the foundation of the house for extra warmth.

The Lapagerias also are sending up new shoots this spring but are killed to the ground each winter. I was lucky enough to get one blossom last fall before the frost got it.

RE: Cleveland Gunnera Survived Winter.

Appreciate the picture and the info.

It appears that the ground is not all that swampy, looks like it grows regular garden soil. I thought that gunnera needed a wetter location.
I am zone 6 and could do the same, also have a greenhouse and can plant in a large pot and bring inside if I needed.

Just shows that that these plants tolerate a wide range of soil conditions, maybe just give them a lots of water
