Giant Rhubarb!

Those huge leaves by the stream need further investigation…

Fabulous if you have the space…

A little nearer now…

I’d love to kid you into thinking it’s rhubarb, but you are all far too clever! (It isn’t even related!)

As I get right up close, I can see sharp prickles, fluffy pink stem bases, and… could those green shoots be the flowers?

Gunnera manicata

(Giant Rhubarb/Mammutblatt)

An amazing herbaceous plant that comes from the southern hemisphere. These have been in this particular garden I visited for many years and have to be kept in check, along with the Bamboo and the Japanese Knotweed! (Japanische Staudenknöterich – Fallopia japonica)

Japanese Knotweed

Are there invasive species threatening your garden or local vicinity?

    • I think Gunnera is only invasive if it likes the conditions, as I have seen smaller ones in other gardens in England where it isn’t a problem. Fortunately we don’t appear to have Chinese Bittersweet here.

    • I think this was one of the first UK gardens to plant Japanese Knotweed in the 19th century – before they knew how invasive it is! They are no longer allowed to plant it in the UK anyway.

    • This “Wild Garden” walk is beautiful – even on a dull cloudy day! The formal gardens at this house have suffered a little from the weather in the UK this year (rain, rain and more rain!) but this wild part has thrived on it!

  1. Nice stroll you took us on. So pretty. Knotweed I think is here as well not really sure I must investigate and yank it out and not keep whacking it down if it is . I love the first shot looks like my place when the Stream is not swelled lol

  2. They have a big patch of Gunnera in the botanic gardens in Edinburgh – looks great right next to the pond. There’s himalayan balsam spreading by rivers and even on road verges round here, but I heard that it’s a good nectar plant for bees, so although it’s invasive maybe there is something good about it.

    • We have that by our canal/river too – beautiful, and attracts bees and butterflies, but suppresses other native waterside plants. I suppose there are pros and cons!

  3. Yes, we have Japanese knotweed, bamboo that can take out foundations, and now we have another couple of vines that are destroying everything in their path. One is the “Five-mile-a-minute” vine (the name gives you some idea of what we’re up against. And the other is “Chinese evergreen” which is often confused with bittersweet around here. People mistakenly starte growing it to make autumn wreathes with…. now it is decimating our woodlands and forests. Before anyone cultivates anything I wish they could do a little research first.

    This morning I came in and heard a very strange sound at my front door coming from under a thick cover of myrtle … it sounded like a cross between a cricket and a frog! I couldn’t see anything but it sure was vocal. Hope I get to see what my new friend is all about.

    • I’ve heard of a fast-growing vine, but not the Chinese evergreen… yet! I wonder what that sound was – do let me know if you find out! A toad perhaps?

  4. oh to have the space to grow it ! Brambles are my biggest problem on the plot, followed by knotweed and then couch grass…..

  5. My parents have a few rhubarb plants in front of the garden my grandfather used to tend in our yard. It has taken up a lot of space and every year my mom’s friend takes some and makes many yummy rhubarb dishes with it!

  6. Oh dear, I´m so gullible 😉 I believed you when you said it was rhubarb without thinking too much about it. We have some kind of vicia in the garden which is all around other flowers at the top of a hat. One moment you don´t see it, the next you have metres of it everywhere.
