Stonecrop / Sedum

'Neon' should look like this in late summer
Sedum spectabile 'Neon'
From Lowe's Summer 2018 but replaced with October Daphne sedum from High Country gardens in 2024

Sedum sieboldi (October Daphne)
From Bluestone Perennials in fall 2018

Sedum kamschaticum
From Plants of the Southwest in spring 2019

'Weihenstephaner's Gold' 
From Sooner Plant Farm in summer 2020


Expectations:
Neon is really eye catching in bloom, but does not flower very long.

October Daphne has arching branching that reach over, and intense, prolific raspberry blooms.

Russian stonecrop is a round bun-shaped ball of clean looking foliage with sparse, light lemon yellow flowers.

'Weihenstephaner's Gold' was a big success in my CT garden, spreading all over to form a tall, thick mat. It bloomed for a long time and very profusely with starry bright yellow and orange tinged flowers.


Experiences:
'Neon' sedum doesn't wow me. It gets nice magenta flowers in late summer, but they are brief.

The foliage is not a bright chartreuse, but rather an odd yellow late in the season, after the flowers fade.

'October Daphne' was in a bowl on the patio in 2019 and grew well, but spilled over late in the season with long, arching stems, and the flowers were only at the very ends, hanging down. Odd. 

I took it out and planted it under the pine tree in the front in mid October 2019 but it never did much or bloomed well there. Finally took it out for good.

In spring 2024 I replaced the 'Neon' sedum in the driveway strip with an October Daphne sedum that can arch over the metal edging of the strip.

'Neon' in 2020 and 2021. Flowering was brief, foliage was odd
Sedum kamschaticum was in the triangle by the front walk but was replaced with 'Weihenstephaner's Gold' in 2020. 

It was a clean looking, tidy plant with great foliage, but not what I was expecting. 

Instead of a low mat of golden starry flowers, the kamschaticum plants were four tight round buns of light green foliage with some lemon yellow flowers sprinkled on them. Clumpy. 

The four buns wound up moved and transplanted to several various spots, finally one landed in the dining room window garden, one under the pine near the front walk, and the other two eliminated.

I wanted 'Weihenstephaner's Gold' kamschaticum with its deep green leaves and warm yellow flowers. It made great rounded forms at the edge of my old gardens. It flowered brightly for a long time in spring, and starry flowers were golden orange-yellow, not lemon. 

So I replaced the Russian stonecrop sedums in the front triangle with Weihenstephaner's Gold, June 2020. 

But it utterly failed, I just could not keep any of the several plants alive! I transplanted some and those failed. 

How could this sturdy sedum have been so robust and successful in CT but a big failure here?
