This one is in bloom now. I keyed it out last year as Penstemon secundiflorus, I thought, based on what's visible in the attached photos (pardon the dirty fingers in the pix!) as well as:
- calyx glabrous, entire to slightly erose
- staminode exerted, expanded to 3mm at the tip, densely bearded to 1/2 its length, mainly on the edges, with long tangled yellow hairs
- anther sacs closed at tips and across connective, or so I thought; glabrous
Does Penstemon secundiflorus seem correct? Thanks in advance for any insight.
