What makes sedums flop like this?
if the soil is a bit rich it can make them flop. Grow them hard in gritty , well drained soil and they're more turgid .
I did a Chelsea Chop in May (as recomm by the forum) - when the plants weren't that big. Below is how they were in July - coming back shorter and sturdier (not flopping). They are now flowering and doing really well - some just going over and some peaking (full sun, sandy soil). It's been a real pleasure to watch how they developed over the year, simple plants at the front of the bed. Snails have discovered them and have been chomping the leaves, which is a shame and the foliage is mangled.

Dividing them will certainly help - it takes a couple of years before they get to full size.
Rich soil definitely encourages more soft growth.
Most of mine are in front of a Hydrangea. Nice and dry, and only get later sun. They just start into growth at the same time as the Hydrangea and it supports them.
Mine are only about a couple of inches tall in mid/late May

Mine that I inherited with the garden used to do this, but when we redid the garden they were moved to the top of a retaining wall and the drainage does wonders. I thin out the stems rather than chelsea chop, so the plant is less congested and there are only nice strong stems left.
Thanks for those suggestions
. I think the drainage is pretty good, but not like the top of a retaining wall.
If at first you don’t succeed, have some cake.
; they flop more on rich soil. Poor(er) and dryer soil suit them quite well. A Chelsea chop does help, you're robbing the plant of some of its all too easy investment.
