Method: we counted every Sow design containing Phlox (4.8k of them), then scored each other plant by how much more often it appears in those designs than in designs generally (lift), requiring at least 40 shared designs. Ranking by lift rather than raw count is what stops the list collapsing into “the most popular plants”.
Phlox pairing questions
What should I plant with Phlox?
Across 4.8k real garden designs containing Phlox, the partner that shows the strongest affinity is Densiformis Yew — it appears alongside Phlox far more often than its overall popularity would predict. The full ranked list is above.
How was this companion list decided?
From data, not opinion. We looked at every Sow design containing Phlox and measured which other plants appear with it more often than chance would explain (a lift score), requiring at least 40 shared designs so nothing here is a small-sample fluke. That is why the list reads like a coherent planting palette rather than a list of bestsellers.
Do companion plants need the same conditions as Phlox?
Yes — that is the first filter. A companion has to share the hardiness range and light exposure, or one of the two will struggle. Each entry above states the zones it shares with Phlox and whether it wants the same light; pairings that differ in bloom time or height are noted, because that contrast is usually the point.
