McAllister’s Phlox: A Hidden Gem for Southern Gardens
If you’re looking for a native wildflower that’s as rare as it is beautiful, McAllister’s phlox (Phlox drummondii mcallisteri) might just be the perfect addition to your garden. This charming annual is a true regional specialty, bringing authentic local character to landscapes in its native range.
What Makes McAllister’s Phlox Special?
McAllister’s phlox is a native forb—essentially a non-woody flowering plant—that grows as an annual, completing its entire life cycle in just one growing season. As a member of the broader Drummond’s phlox family, it shares the characteristic colorful blooms that make phlox species so beloved by gardeners and pollinators alike.
This plant holds special significance for native plant enthusiasts because of its limited geographic range. Unlike many wildflowers that spread across multiple states, McAllister’s phlox calls only Oklahoma and Texas home, making it a true regional treasure.
Where Does It Naturally Grow?
McAllister’s phlox has one of the most restricted native ranges of any phlox variety, growing exclusively in Oklahoma and Texas. This limited distribution makes it particularly valuable for gardeners in these states who want to support truly local biodiversity.
Why Plant McAllister’s Phlox?
There are several compelling reasons to consider adding this native beauty to your garden:
- True native status: Supporting local ecosystems by growing plants that evolved in your specific region
- Pollinator support: Like other phlox species, it likely provides nectar for butterflies and other beneficial insects
- Low maintenance: As a native annual, it’s adapted to local growing conditions
- Unique garden character: Its limited range makes it a conversation starter and adds regional authenticity
