hylotelephium Sedum ‘Purple Emperor’

Peggy7Peggy7 Posts: 34
I saw an episode of Gardeners World late last year where Carol said you should cut back your hylotelephium in the spring when it start growing so it becomes strong and upright rather than falling over.  Every year this plant gives a lovely display but tends to flop over once it becomes too heavy.  I can’t seem to find this programme so I could revisit what Carol said about how to stop this.  Does anyone have any advice please?

    Have a look here Peggy, there’s a list of other plants that benefit from a Chelsea Chop as well.

    If you grow them in very dry free draining soil, and in full sun they are less likely to put on excessive growth. These plants tend to flop and open up in the middle when the soil is rich or with a bit of shade.

    Round about now or in the next few weeks, just snip all the growth down by about half of its current height, and you will have more stout and stiff plants that will not be as tall, but still have a lot of flower-heads.

    ...and the bits you cut off all become cuttings!!!

    Hi Peggy, do you find your plant gets munched by slugs/snails. Mine got trashed last year, but other varieties seem untouched. I ended up putting in a pot on a table!

    Hi Lizzie, I've never noticed slugs or snails munching at this particular plant.  We have it in a raised bed with a rose bush in the middle.  I don't think this would make any difference, but will keep an eye on it this year.
