Got the taller type that flop open. Tried staking -and other ways. But thinking of taking some out. But like to have some color in late fall.
I have some with flowewr stalks that are around 12-15 inches high and they are upright. However, yours may be an entirely different type to the ones I have. :-?
Do you have the big pink flowered ones? if they are in the shade I don't think they grow as sturdy as in full sun. I have the small gold flowered one and it is more for a rock garden than flower bed. It seems to naturally trail down the wall, but then the flower stands up from the area it is resting on.
I like the color of Autumn Joy Sedum in the fall too. It is very popular in a lot of my "work" gardens. It doesn't like to be wet, this causes the floppiness. I tell folks to skip over it when watering, it is quite drought tolerant. I also like to cut it back by about half in late spring so it can't get too tall and lanky. This helps produce more blooms too.
I always use green twine, midway up the stalk, just to hold them all together. If it is a large clump, I make 2 concentric circles. It works well
I Have water them some-but not as much as other plant. But think next year will cut it back. Couple going to move to another area. Kinda Focal point close to arbor.Got grow through frame one-other put couple big pots Bracing it against arbor. see I can find picture.
I think Kay gave the secret to good Sedum. Trimming back earlier & grow dry. Most of us probably have Autumn Joy. I like one called Matrona.I think I have one. sNs
I have both type.One lady who came over. Said she didn't like them-because when they look real pretty in fall. Winter is close to behind. But next season will cut them down. Some taking to local park.God's watering them now.
