The Mystery of Polygonum polycnemoides var. oliveri: A Gardener’s Detective Story
Sometimes in the world of native gardening, we encounter plant names that send us down rabbit holes of botanical mystery. Polygonum polycnemoides var. oliveri is one such enigma – a plant variety that seems to exist more in taxonomic limbo than in actual gardens.
What’s in a Name? The Taxonomic Puzzle
Here’s where things get interesting (and a bit frustrating): reliable information about Polygonum polycnemoides var. oliveri is virtually nonexistent in current botanical literature. This could mean several things – the variety may be extremely rare, the name might be outdated, or it could be a taxonomic designation that’s fallen out of use.
The genus Polygonum has been through major reshuffling over the past few decades. Many plants that were once called Polygonum have been moved to other genera like Persicaria, Fallopia, and Reynoutria. It’s entirely possible that what was once known as Polygonum polycnemoides var. oliveri now goes by a completely different name.
Should You Try to Grow This Mystery Plant?
Given the lack of available information, growing this particular variety presents some challenges:
- No reliable source for seeds or plants
- Unknown growing requirements
- Unclear native status and geographic distribution
- No information about potential benefits to wildlife or pollinators
Without basic information about native range, growing conditions, or even confirmation that this variety is currently recognized, it’s difficult to recommend seeking it out for your garden.
