Aloinopsis x 'Latigra'
Aloinopsis x 'Latigra' is a hybrid that we grow vegetatively so they stay true to color. Plants can take -10F if good drainage is provided. Plants can reach 6-8" across and flower during the spring and fall months. They can put on quite a display.
I do not guarantee these in a zone 5/6 because everyones growing conditions are different but this would be a good trial plant to grow in your cold outdoor garden. Try to plant outdoor 90 days before 1st hard freeze.
