Can you take cuttings and put them in water to grow roots, the same as you can fushia's, had anybody done this. I do not seem to have much success in taking penstemon cuttings the normal way.

Yes - I always root my Penstemons in water, as I don't get as much success in compost. As soon as you can see a decent rootball, pot them up. Don't do it until there are plenty of roots, though.

i find the opposite. straight into compost most take. start in water most rot. isnt that funny. so do what you prefer or try both methods and see which you have more luck with.

My wife regularly does penstemon cuttings in water. Takes a few weeks for decent root systems to emerge but , yes, it works well.
