Plants you really wouldn't have in your garden

Euphorbia - they just look alien to me. Houttuynia cordata, or anything variegated with red, green and cream; it looks artificial.

 

Just remembered Penstemons and African Violets.
Tree lilies, what's wrong with Cardocinums if you want big lilies, Star Gazer Lilies.

 

Yellow daisies of any description, Valerian, Erigeron, small-flowered Asters, single flowered roses, Cotoneaster horizontalis, for purely practical reasons anything spiky (apart from citrus trees and Agaves), Dipladenias, native water plants and most 'wildflowers'. Love to see wildflowers in the wild but not in my garden!

 

I don't like big flowered plants so that immediately puts Hydrangeas and Rhododendrons out of my garden. Laurels, particularly the paint splattered ones, two of three which are still waiting to be dug out of my newish garden. Euphorbias, Bluebells, Tulips and Muscari. I'll stop there but add I'm not keen on pink flowers.

 

Bergenia, Begonia…..

 

Would that be any plant that begins with 'B' @Bluejayway?

 

Are we allowed to defend any of these nominations or would that be classified as incitement?

 

Cherry blossom trees with reddish coppery leaves, they’ve got to have green leaves, otherwise they look really odd to me.

 

Tree Peonies is another I can do without - 2 in this garden which I haven't managed to dig out yet. I like the flowers but they seem so short lived.
I wonder how many "smart" plants are able to read this thread and are already shrivelling from embarassment

 

Nice one @Sheal !

 

Yucca and Mahonia!

 

Another one that looks completely artificial to me is Callicarpa a.k.a Beauty Berry. That shade of purple is just wrong!

 

Pampas grass. And any other grasses that don't easily shed the old leaves and just get more and more tatty until bits start to come loose and blow around the garden.
Cordylines, phormiums etc for the same reason.

 

I love posts like this one

Definitely spotted laurel, which has been mentioned a few times already.

Any conifer whatsoever - though some are interesting, after my past experience with leylandii (that the house had when I bought it), I don't want anything in that plant family Sometimes I even look at my heathers and think that they almost look like conifers that someone shot with a shrink ray (it's the foliage..) and and in that moment I am tempted to get rid of them.

I am not a huge fan of hydrangeas, though there are exceptions.

I am also a bit of a snob regarding roses. I really love some of them (mostly David Austin & some of the pollinator friendly ones) but I find others really boring.

 

We inherited Houttynia and have been trying to eradicate it for years now. It's only redeeming feature is that it smells quite nice when you pull it up.
