Another surprise when I got home from work today: my Persicaria sp. 'Porto Velho' is budding. Hoping for flowers soon, though Persicaria are difficult to catch with flowers open so no guarantee of pics... in any case, these are the buds:
Note the cute little pink tips
That said, the P. 'Porto Velho' looks suspiciously like P. praetermissa (formerly P. sp. 'Ruby') except that it hails from completely the wrong continent - P. praetermissa is native to Southeast Asia and Australia; P. sp. 'Porto Velho' comes from Brazil. It could be a lookalike very close relative.
Also, I harvested some seed pods from my Staurogyne sp. 'Bihar' - see the first page of this thread for photos of the flowers and developing fruit. The pods are roughly 7-8mm long, with a tough outer shell:
No idea if these pods contain fertile seeds, but I'm going to bag 'em, tag 'em, and mail
'em to Cavan if he wants them. Perhaps it'll help pin down an ID for the species. The plant is still developing more pods, so maybe I'll see if the next batch can be germinated.
