Anybody ever planted seeds of a Gunnera Manicata?

I was wondering how long it takes them to come up? I bought some off Ebay last year and was TOTALLY SHOCKED at the teeny tiny size of them when I got them in the mail. With such a huge plant I was expecting larger seed. lol Anyway I planted them a few days ago and was just wondering how long they would take to come up. Thanx!!! I think it's also called a giant rubbarb sp?.

No I haven't planted a seed but I do have one of these plants. I covered it with a THICK layer of mulch and plastic bubble wrap for the winter. I was wandering through the yard yesterday and I noticed the plastic cover on top of my Gunnera was pulled very tight. I removed the rocks holding down the plastic and pulled it away. I literally watched two arm sized branches emerge from the mulch and stand up straight. I almost thought the thing was going to reach out and grab me!

My Gunnera didn't get very big last year but something tells me that will change this summer. I'm very afraid. :)

I have tried twice this year. The first time I started some inside with no luck. I now have a new batch started outside. No luck with them either! I'm going to keep the soil moist for another month just to make sure.

I am making a second try at it. I am told that these tiny seeds can take months to germinate.

Mine still hasn't came up and I'm still waiting. I know it's been a month now or longer that they've been planted.

Gunnera manicata: good info on this plant can be found here, but don't try to order seeds from here for shipping to USA, you will need a ppq-587 form and permit from USDA. 1 month wait on USDA permit approval so far for these seeds,and still pending. note: not suppliers fault but they did require a permit, the USDA is the hold up, was told it can take up to 45 days to 2 months for approval, and a level 2-access pain.

I'm the Seattle area and I winter sow the fresh seeds. I tried gunnera from Thompson & Morgan seed one time and got zero germination. I think it needs to be sown fresh and never dry out. This makes sense if you consider where gunneras grow--in the cloud forest where it never dries out. For this plant to succeed it would need to cope with constant cold rain and mist. And it probably grows up to the frost/snow line too.
The way to go is get a fresh seed stalk this fall. I just cut the seeds heads off the main stalk with a big knife, let the chunks fall on top of the sowing medium. Then sink the pot into the ground and let it sit for the winter. Perhaps a light layer of leaves to protect from drying out. Let the winter rains and cold stratify the seeds. All the pulp will rot away by spring. It got down to 13 degrees here last winter so I know that those seeds froze. Even so, germination was high--90+%.

I would love to have some of your fresh seeds.....I could trade something or send postage. I have also planted online purchased seeds-not sure of their freshness/viability..still no seedlings..
PLMK if you are willing to share some of yours.

mine self sows EVERYWHERE! The seedlings are tiny, then they develop into primrose-like plants before sending up its first adult leaf. The weird thing is, when I planted seeds deliberately, nothing grew. But now, seedlings are appearing all over the lawn, around the mother plant, and in drains!
Good luck with

I know this is an older thread but anyway, I read that oils from your skin can interfere with germination. Here's the refrence, I hope it helps someone else considering trying these from seed.

A friend gave me a gunnera a few years back. It naturally gave birth to 4-5 new plants. I've removed the seed pods and so appreciate all the details on how to plant. I did leave some of the seed pods in the bog where the largest happiest gunnera live. My original plant is now HUGE with leaf span being 3-5 feet across! I am on the Southern Coast of Oregon. I haven't protected it from our winters without any sign of damage.
