Sedum sexangulare - A Hardy succulent

Sedum sexangulare – Fine Hypertufa Plant

I have another great plant for hypertufa planters!

It is sedum sexangulare and it is a great hardy sedum for those of us in the colder zones. Its statistics say it is good from zones 3-8 and I can sure testify that is has grown well here in Ohio in zone 5/6.

I have grown this all last year and it did well all winter and has “overwhelmed” the big  side of the large hypertufa planter I have it in. I have no negatives about it unless growing so fast is a negative?  It is a low and spreading plant also called  six-sided stonecrop.

My largest hypertufa trough - so far

I have this one in my huge T Rex Trough and it is filling in nicely, and up to this point, it is playing nicely with its neighbors but maybe getting larger than I want for this particular trough. I have it next to the Erodium reichardii ( Baby Swiss Geranium) and they were intermingling somewhat. I have had a problem with my Erodium these past years since it didn’t seem to survive, but I purchased more. I love it so much.

I kept the Erodium inside this winter, and I am happy to say it survived and is blooming fine.
But all my plants in the T Rex are doing well. I have it filled mostly with various succulents and sedum. 
Tender sedum similar to sexangulare - Crassula from

This plant is similar to another plant which is in the genus of  Crassula. I have seen both these plants listed as a Watch Chain plant. But the Crassula lycopodioides or muscosa is a different plant which is a tender perennial for me. It is listed for zone 9-11. I have this plant also but it is one that I have to take inside for the winter, as opposed to the Sedum sexangulare that is good for wintering outside.

Stats on the sedum sexangulare:

  • Height: 6 inches
  • Spread: 6-9 inches
  • Zone: 3-8
  • Location:  sun, drought-tolerant; suitable for xeriscaping
  • Blooms: small yellow blooms in mid-spring to early summer

I can recommend this plant for a hypertufa trough since it is very drought tolerant. I purchased a small 5″ pot in spring 2014 , and it has far exceeded the reach estimated. It grows thickly which allows it to smother any weeds which may try to grow up through it. And I have read on a few sources that it is easy to propagate by just pulling or cutting off a clipping and putting it where you want it to grow.

Based on that information,  I will be sprouting more for the new hypertufa pots I have made. I think it will work out fine for my garden. After it finishes blooming, I will give it a crew cut and take a lot of the cuttings and spread them into my Nursery planters. I will have a lot of this to share for next year’s Plant Sales.

So what are you planning for your garden this year? And what is in the works for making some more hypertufa planters?
