Got a clipping of this from a friend when I was still living in California. It survived the move and this is the first time it has ever bloomed for me!

We moved to an apartment that allowed dogs, then waited 6 months to get an appt at a shelter because of COVID. We went to see about another dog but my partner spotted Riley. He had been a stray and was pretty timid at first, but once we spent a bit of time with him, we weren’t leaving without him!

It’s so elegant but I know I’m closer to this version
