 Common Name: Stonecrop-Autumn

Absolutely the most rigidly upright sedum we offer!  If you have had trouble with sedum opening up on you in the past, you’ve got to try ‘T Rex’.  In our trials, despite its height and the heavy weight of its large flower clusters, the plants remained tidy and compact all season and never opened up like some other varieties. 

The green leaves had sharply toothed edges, adding to this plant’s appeal before it bloomed.  In late summer, clusters of greenish cream buds covered the entire clump, then opened to light rose pink flowers similar to its parent, ‘Autumn Joy’.  Move over AJ, there’s a new kid in town! 

‘T Rex’ exhibits a greater resistance to stem rot than older cultivars such as 'Autumn Joy'.  It is a tremendous improvement!

Tall, upright sedums form substantial clumps of foliage which can be substituted for shrubs in the landscape. Their stout, sturdy stems support the massive flower heads which develop in summer and burst into bloom in fall. If left standing, they provide winter interest and food for birds.

Homeowner Growing & Maintenance Tips:

Sedum is one of the most popular perennials grown in American gardens because it is very easy to grow and hardy in most areas of the country. Because of its thick, succulent leaves which can store water, sedum is drought tolerant. It should be sited in average to poor soil that is well-drained. Plants grown in rich soil tend to be lanky and open. Most varieties should be grown in full sun to light shade. The lower growing types, however, will survive in partial shade.

Divide sedum every 3-4 years to maintain its compact growth habit. Older plants tend to split in the center if they have not been divided. Pinching the taller varieties back by half in early summer will also help prevent them from splitting. This plant is not usually bothered by pests or diseases. The seed heads of the taller varieties provide excellent winter interest and food for birds. Remove them in spring when the new growth begins to show.
