Tall narrow planters for either side of front door?

[greatbighillofhope]

I need something to go either side of my front door, it’s only narrow (20cm wide each side) in the open porch but leaving it empty looks really bare. I’m struggling to find anything the right size. Then I would need fake topiary narrow enough too. Unless anyone has better idea for making it look like a proper, welcoming front entrance?

Aldi have rattan effect tall planters just now. Square or tapered at top. Grey or natural £14.99. Not sure if measurements below 20 cm tho

What do the Aldi tall planters look like please? I haven't seen any.

Thanks will take a look

Here you go. They are quite lightweight. The earth “bucket” doesn’t go all the way down.

In situ. The little one is £9.99
