the success on rooting bloomstalks depends on the size of the small leaves at the node where peduncle - the main bloomstalk branches into pedicels - stalks that carry single blossom.
Big leaves - it roots - smallish - probably not. Some old varieties have large ones - and root just right - or produce "baskets". Basket happens when the sleeping bud at the above mentioned node wakes up and starts growing producing a hanging palntlet you can separate and root.

I do not think you can root the bloomstalk of a Streptocarpus - the leaves at this node are miniscule. But - they often produce baskets and this baskets sometimes even produce a new bloomstalk with a blossom.

It is variety dependent - some of Bristols streps do it consistently.

Irina,
