I’d read about xHeucherella ‘Copper Cascade’ and it sounded wonderful. A small-leaved trailer or ground cover with rosy coppery gold leaves all the year round. It seemed ideal to cover the bare soil around the edge of one of our dark-leaved Physocarpus opulifolius ‘Mindia’ – known as Coppertina in North America and as Diable d’Or in Europe – with its amber shoot tips.

So when I spotted a ‘Copper Cascade’ in a nursery on my way back from cardiac rehab a few weeks back – I immediately put it in the cart. But I should have looked more carefully. OK, it was in an 8in pot, but when I got to the checkout I discovered, to my shock, that the price of this one plant was – $19.99! (plus sales tax). Twenty bucks! I’m glad my creaky heart could take the shock. For Brits that’s £11.73.

Now, over the years, I’ve more than once said here that plants are too cheap but twenty dollars for one Heucherella is just too much. I’m not sure how much the White Flower Farm branding has upped the price - they have to take their cut, after all – but don’t you think that price is a bit steep?

White Flower Farm are not offering ‘Copper Cascade’ on their website, but the related ‘Redstone Falls’ sells for $19.45 (plus $9.95 shipping) (£17.14) in a 3in pot which is even less of a bargain. Almost thirty dollars for one heucherella in a 3in pot…! Come on, be reasonable…
