Rice Button Aster: A Lesser-Known Native Gem for Southeastern Gardens

If you’re a native plant enthusiast always on the hunt for something a little different, let me introduce you to the rice button aster (Symphyotrichum dumosum var. pergracile). This charming perennial might not be the most famous member of the aster family, but it’s a true native treasure that deserves a spot in the right garden.

What Makes Rice Button Aster Special?

Rice button aster is a perennial forb, which simply means it’s a non-woody plant that comes back year after year. As part of the aromatic aster complex, it shares many delightful characteristics with its better-known cousins, including those classic small, daisy-like flowers that make asters so beloved in fall gardens.

You might also see this plant listed under its old scientific name, Aster dumosus var. pergracilis, if you’re browsing older gardening resources or plant catalogs.

Where Does It Call Home?

This variety has quite a limited native range, naturally occurring only in North Carolina and South Carolina. It’s what we might call a regional specialty – a plant that’s perfectly adapted to its specific corner of the world.

Should You Plant Rice Button Aster?

Here’s where things get a bit tricky. While rice button aster is undoubtedly a worthy native plant, it’s also somewhat of a mystery in the gardening world. Information about this specific variety is surprisingly limited, which means you might face some challenges:

  • Finding plants or seeds may be difficult
  • Specific growing requirements aren’t well-documented
  • You’ll likely need to source from specialty native plant nurseries

That said, if you’re in the Carolinas and love supporting truly local native species, this could be an exciting addition to your garden. Just be prepared for a bit of detective work!

Growing Rice Button Aster (What We Know)

Since detailed growing information for this variety is scarce, your best bet is to treat it similarly to other members of the aromatic aster group. Here are some general guidelines:

  • As a southeastern native, it should handle typical regional climate conditions
  • Most asters prefer full sun to partial shade
  • Well-draining soil is usually preferred
  • Fall blooming period typical for the aster family
  • Perennial growth habit means it should return each year

Alternative Options

If you can’t locate rice button aster or want something more readily available, consider these related southeastern native asters:

  • Aromatic aster (Symphyotrichum oblongifolium)
  • Smooth aster (Symphyotrichum laeve)
  • New England aster (Symphyotrichum novae-angliae)

The Bottom Line

Rice button aster represents the fascinating world of regional plant varieties – those special forms that evolved in specific places and nowhere else. While it might be challenging to find and grow, it offers the unique opportunity to cultivate something truly special and local. If you’re up for the adventure and can source it responsibly, this little-known native could become a treasured part of your southeastern garden story.

Just remember: with native plants this specialized, patience and persistence are your best gardening tools!
