Cutting back or deadheading penstemon?
I had a few different varities but only two came back this year and I'm not sure how I handle them! I have the Penstemon Violeta Oscuro (Violet Dusk) which bloomed beautifully for a few weeks and now appears to be done. I also have the Penstemon X Mexicali (Pikes Peak Purple) that just started to bloom in the last few weeks but I'm sure I'll have to tend to that soon. Do you dead head or cut back? And if I dead head...how do I tell when it's the bud or the seed? I thought I had it figured out but I'm not sure and there are so many buds at times on the Violet one that I can't remember which was blooming the day before and which wasn't! LOL
