One of the smaller representatives of the genus is Ipomopsis congesta with up to eight subspecies found across western North America.
 
One of the choicest of these is subspecies montana. It is found at high altitude along the Sierra Nevada Range. From 7000' -12,000' in elevation on lose well drained granite screes. The gray/green fuzzy buns are no more than 1/2" tall and about 2-3"across in their first year. In flower, their second year, the buns are studded with 1" balls of tiny pink flowers tipped with blue anthers.

This would be a great addition to a raised trough since you have the get up and personal to see the details.
 
I have had luck getting it to reseed on a scree bed.

Is that one of your plants, John?  Impressively captivating! 

I just love blue anthers.
