There is a webcam in my office that I use to take photos of the whiteboard. This setup was inspired by Dror Bar Natan’s Blackboard Shots. If you know of anyone else with a similar setup, please let me know.

First Bloom: Eucodonia Adele

Fri, 28 Aug 2026 20:40:44 -0400

Attention conservation notice:

I got a rhizome of this at the Lakeshore AVS Spring Sale 2026. It is my first eucodonia. A sort of funny Dr. Seuss plant. Huge foliage and tiny little flowers. A sort of streptocarpus with massive leaves. Now that I have a eucodonia, primulina kohleria, two streptocarpi, and a bunch of violets around, I am starting to get a feel for a small part of the gesneriad family. I enjoy the family resemblances.
