Grusonia clavata Giant form
Grusonia clavata GIANT FORM or Dog cholla is a real nice plant than can make mats up to 3ft across, they more commonly are 18". Plants have taken -22F many times and have been a real strong grower for us. Yellow to orange flowers in June. This is the Giant stemmed form, heads are nearly double the traditional Grusonia clavata.
I do not guarantee these in a zone 5 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.
