I am a big fan of Hebe, esp. "Wiri Blush". Have them all over the garden.

Here's the weird thing, for example: Three in a bed; two will die and
the other flourish. Has happened several times. They all get the same
conditions. This happens sometimes a year or two after planting.

Can one plant be inherently "feeble" and another not?

Could be. Have you considered propagating the survivors via cuttings?
I hear it is easy with hebes.

You raise a question I've been battling with.

I want to propagate a lovely white azalea that is sprawling all over. My gardener assures me it can't be done. There are enough low-growing branches that need pruning anyway, so I'm willing to try. BUT I have never understood cutting vs twisting. The former is supposed to be a no-no, but why? I've tried to do research on-line but not fpund answers.

So I'm asking you & other kind NG members for input on cutting vs twisting, both for the surviving Hebe and for the azalea.

TIA
