Does Penstemon hirsutus (Hairy Beardtongue) Make a Good Cut Flower? 

I so enjoy watching these cut flowers videos, even though I don’t do cut flowers.

Are you cutting the stems at an angle and cleaning the vase & fresh water daily? When a flower is cut the stem forms a 'callus' at the end so cutting the stem an angle helps the stem take up fresh water. Also removing all foliage on the stems concentrates energy to keeping blooms fresh. :-)
