Sedum 'Vera Jameson' is a great little stonecrop - unassuming, yet reliable and constant she will blend into most planting sites and combinations of plants nicely, and provide some medium sized foliage as well.
This is one tough little plant, don't let the name fool you; totally abandoned in a garden bed, this stonecrop will battle along without missing a beat.
I've had one little plant that struggled away, combating weeds, competition from larger more assertive stonecrops and Sempervivum, and she survives just fine.
This is another mid sized type of Sedum. The taller border types are all over 35 cm (14" or so) and then there are the lower growing groundcovers that are all low and creeping. Sedum 'Vera Jameson' and Sedum ussuriense 'Turkish Delight' are both somewhere in the middle, at around 15 cm (5") and a bit taller when flowering.
This makes them a perfect liason plant - bridging the gap between the tall types and the groundcovers. Having the trait of unusual colored flowers doesn't hurt either, adding to the textures and colors of a Sedum tapestry or xeriscape garden.
