Gardeners' Notes:


On Jul 11, 2021, Rests from Bryan, TX wrote:

I was told that this sedum needed very little water. I have found this to not be true in Zone 8b. The plants in my flower bed growing the best are the ones that are in soil that holds a lot of moisture. Most of the sedum was doing horrible until we got almost a monsoon of rain. Over 6 inches of rain. It is doing a little better, but still not doing the best in the world. "Lemon Coral" is a much better choice. It can pretty much grow in all conditions. Sun or shade. Wet or dry.

The first house I moved into had these growing outside. When I moved I forgot to grab some. So I snuck back over there and ripped out a handful. I got them home and planted them after a few weeks they all died, or so I thought. When I was reusing the dirt I found one tiny green plant that had gotten buried. I laid it in one of my other plants and forgot about it. The following year I noticed it and this year it TOOK OFF! It is doing amazingly and has spread. I planted it with a small tree my husband pulled off the side of a mountain because I liked the flowers. It has covered every inch of dirt there is!

This sedum does very well in OKC, zone 7 or 7 b. I have it scattered about the yard where other types of ground cover have a difficult time growing because of the heat, poor soil, or slope. I've tried other sedum but this is the most reliable for me.

This is a cute little guy, but it is no match for bindweed (Convolvulus arvensis). When I go to untangle it from the bindweed, its fragile little leaves and stems break off like spun glass.

This is a wonderful little groundcover. Mine is growing in gravel around my mailbox. When it spreads out farther than I want it, it is easily pulled up; the roots are shallow. When it blooms, it is a sea of gold, but be sure to deadhead immediately. The year that I let the flowers go to seed, it looked very unattractive once I finally cut the seedheads off and didn't look good again until the next spring. It was just spent and floppy and sparse. Since then, though, it's been full and vigorous--really filling in its space well.

I purchased this plant in a hanging basket several months ago. I hope it will make it in the hot, humid summer of central Florida. Anyone with experience?

This is a very prolific and healthy sedum in my zone 5 garden. Winter doesn't even faze it! It spreads slowly and is non-invasive and it adds a nice touch to a rock garden.

I grew this plant in 5b with no problems. It can get too leggy as a groundcover on its own, but it makes a lovely addition to a rock garden. The blue-green foliage contrasts well with deep red & green sedums & sempervivums. A slow spreader compared to Sedum album. Tolerated very dry, shallow soil and filtered shade.

Nice color of foliage, doesn't bloom consistently- some years not at all, likes to grow out of it's space rather than fill in.

This sedum grows like a weed in my garden. At the other hand it provides in wintergreens and it likes to grow under my Leylandii hedge...a difficult place for plants. In earlier days it was also used as a vegetable ( in soups, dressingss, raw in salads...taste is sour with a touch of bitterness) and as a herb (should help to stop bleedings, cure ulcers and open wounds). Here in Netherlands we call it Tripmadam..
Propagation is very easy. Just break or cut of pieces of the plant and plant it where ever you want it to grow. It roots quick.
Sedums can be very well used as a roofcover..they need nearly no soil to grow and can stand harsh conditions like heat and sun.

Plymouth, UK. Sedum rupestre is a synonym for Sedum reflexum. In this area it is commonly naturalized on old walls. It originates from continental Europe. Not garden-worthy here.
