Penstemons grow so well here in Cardiff by the sea that unless you have a bad aversion to them, it would be rude not to grow a few. It’s the gulf stream. Being a little on the tender side, further inland they get knocked back by the cold. You should cut them back by half in autumn so that there isn’t so much top growth left that they get pulled about too much in the wind, but there’s enough to protect the stems (and shoots) at the base of the plants from the cold.
My rather sad looking Penstemons (unknown variety)
Here, in the mild sea air, they can often get through the winter pretty much untouched, and the purpose of cutting them back is mainly to stop them growing too big and leggy. Not this year though. This year my penstemons came through the winter looking worse than Monty Don’s, even though he lives in Herefordshire, which is generally much colder than here. Maybe he got less snow than us. I was away, in warm sunny Australia (more to follow in later posts) so I didn’t see it, but I’m hearing tales from my customers of how the snow drifted and piled up against their doors five feet high, so that they really were snowed in. Will the Penstemons pull through? I’m keeping my fingers crossed, but I’m quietly confident.
And the Penstemons aren’t the only casualties of the weather. Here’s that Kangaroo Paw I was crowing about before I went away, but which took a pounding once the weather turned.
Anigothanthos manglesii (Red and Green Kangaroo Paw) – though I doubt even it’s mother would recognise it now.
The perennial wallflowers can make a good show. I particularly like Erisymum ‘Bowles’ Mauve’. They’re short lived plants, quickly going leggy and unsightly, but it’s really easy to take cuttings. Taking the cuttings might be easy, but I’ve never had much luck growing them on. Maybe they don’t like my soil, but they never seem to make good, bushy plants. But the snow seems to have just about finished them off.
Erysimum ‘Bowles’ Mauve’ – Not exactly gracing the garden.
Still, at least not everything in the garden is looking sadder than Harvey Weinstein at an awards ceremony for gentlemanly behaviour (what – too soon?) Here are a few of the success stories:
Camassia cusickii – I split one clump into six at the end of last year, and they’re all romping away. The flower spikes are a lovely pale blue.
Some of the lilies in pots are beginning to get going – this is ‘Original Love’, a large, deep red variety.
We’ve quite a few other bulbs coming through as well, in pots as well as in the ground. We’ve got Tulips, including ‘Ballerina’, ‘Prinses Irene’, ‘Purissima’ and ‘Queen of Night’. We’ve got Daffs, including ‘Hawera’ and the lovely ‘Thalia’. And we’ve got some very pretty little blue numbers, including Scilla sibirica and Chionodoxa.
