Looking after Penstemon plants

[ANewDoll]

My penstemon plants have been brilliant this year (free plugs from Daily Mail received early in the year) and have flowered constantly in the last 8 weeks. Some of the blooms have now died - do I deadhead and if I do, how far down the stalk do I cut?

They are currently in pots but will they survive a transplant into my perennial bed? When would be a good time to do this?

cut back the spent blooms as far as you can and plant out into a permanent bed as soon as you like as they are pot grown. I've grown some from seed this year and they are in a nursery bed but will put them into their proper home late summer/early autumn

Gatekeeper Thanks for advice - much appreciated!

But they can be difficult to get through the winter. Especially, they don't like wet conditions and exposed areas.

We have failed previously, but now have Blackbird, which seems more hardy than some, and has done well for a couple of years.

I usually take a few cuttings of favourite ones just incase they snuff it during winter
