Penstemon cuttings

2

Posts

  • I have just taken delivery of some tiny cell type Penstemons from T&M. I am going to pot them on into some 5cm pots. Will they be ok if I leave them at a sheltered  corner outside for about a month? I should be moving into a new house which comes with a greenhouse in a month's time. Lucky me! I am planning to move them into the greenhouse when we have moved. Hope the weather is kind until then...

    Thanksimage

    Personally I wouldnt leave them outside, but I do pamper my plants a bit., you see, penstemons dont always survive their first winter even if they went in as big plants.

    Can they share you bedroom jjust for now.

    CT, you will know when they root as the roots will show out the bottom of the pot. They will be showing new healthy leaves.

    I took penstemmon cuttings earlier in the year, I just put them in 9cm pots with general potting compost and kept them slightly damp.  They have been in my cold greenhouse and will stay there until spring.  I will water them less in the winter, they are doing really well at the moment so fingers crossed.

    Hi from Kingswinford in the West Midlands
  • Thank you Lyn for your advise. I have put them on the windowsill in the living room. It should keep them nice and snug.

    Yviestevie & CT, good luck with yours!

    Sorry but I have a lot of Penstemon questions here .

    I have quickly read the above. I have just bought two Penstemon  Appleblossom  and  2 Phoenix Red. They were on the  search and rescue bed for £3 each Instead of £9. 

    I have collected seed pods of both. given the plants a good haircut and cleaned up the dead leaves and blossoms on the plant. They look perfectly healthy.

    Now what should I do?  Put them in the garden to finish off or nurture them in pots in my !nursery bed !until its time to get them under shelter?

    I have noted that the plants seem to put out roots from the stems.  Would those roots start to grow out as possible new seedlings now, well that is worth a try whatever nothing to loose there.

    I have a cold frame under the wide eaves of the the house which shelters quite well. I have an un heated potting shed and  an alcove against the Garage which sucessfully housed the pelargoniums last winter.   

    Any thoughts on what best to do from here?

    I am in south east Cheshire which has been  relatively mild most years apart from  2010 2011.  

    I have tried Penstemon in the past with no success but  being retired does allow a lot more time for such ventures. and winters seem to becoming very less cold.  (Dont take it for granted though.)

    Grew penstemons for the first time this year. Got hooked and I've bought several varieties.

    I just pull off a non flowering shoot and put it in water. It roots within weeks and I pot them up.

    Several of the ones I did early on  in the year are in the ground and doing well already.

    I've no idea which is which because I stuck them in a jar of water togetherimage so I won't know until they flower  next year which ones have survived the winter.

    In London. Keen but lazy.

    I have just been taking penstemmon cuttings today, and have put them in small pots and covered them with a dome, such as I have done successfully in the past.  But I like the idea of just popping them in water to take root, so I am going to try that as well (with labels image)

    Me too!  I have the same issue but mine is with dayllies.   I now have a rough idea of which  variety is where in the bed,  but I did not make a note.image I split up lots of them. They will show what they are in a year or so .

    Like anyone else, I love a voyage of discovery, B3.  Trouble is, it can sometimes result in a mix of colour that just doesn't work (shocking pink and orange anyone?  Thought not!)  But I do identify with the day lily problem.  Trouble is, they only last a day (!) and I forget to nip out and label/colour code them, swearing I'll remember the burgundy one, the pink one, the cream one, the . . . . . . . well, you get the picture.  But they are a reliable and beautiful addition to a garden, much like the penstemmons that flower all summer long.
