Aster alpinus var. serpentimontanus: A Mysterious Alpine Variety

If you’ve stumbled upon the name Aster alpinus var. serpentimontanus in your botanical wanderings, you’ve discovered one of gardening’s more elusive characters. This particular variety of alpine aster is something of a botanical mystery, with limited information available even in specialized plant databases.

What We Know (And Don’t Know)

Aster alpinus var. serpentimontanus goes by the synonym Aster serpentimontanus Tamamsch., but beyond this taxonomic detail, concrete information about this specific variety remains surprisingly scarce. Unlike many popular garden plants with well-documented common names and growing requirements, this alpine aster variety seems to exist in the shadows of botanical literature.

Geographic Distribution

The geographic range and native status of Aster alpinus var. serpentimontanus remains unclear from available sources. This lack of documentation makes it difficult to determine where this variety naturally occurs or whether it might be suitable for cultivation in specific regions.

The Challenge for Gardeners

Here’s where things get tricky for garden enthusiasts. Without reliable information about this variety’s:

  • Specific growing requirements
  • Cold hardiness zones
  • Mature size and growth habit
  • Preferred soil conditions
  • Water needs
  • Pollinator relationships

It becomes nearly impossible to provide concrete growing advice or recommend whether this plant would be a good fit for your garden.

A Word of Caution

The scarcity of information about Aster alpinus var. serpentimontanus raises some important considerations for gardeners:

First, this variety might be extremely rare or have a very limited natural range. If you do encounter this plant for sale or in the wild, it’s crucial to ensure any material is responsibly sourced and legally obtained.

Second, without knowing its invasive potential, geographic origin, or ecological relationships, introducing this plant to your garden could present unknown risks.

Better-Documented Alternatives

If you’re drawn to alpine asters for their mountain charm and late-season blooms, consider exploring better-documented species and varieties within the Aster genus (now often classified under Symphyotrichum). These alternatives offer:

  • Well-established growing requirements
  • Known pollinator benefits
  • Documented native ranges
  • Reliable availability from reputable nurseries

The Bottom Line

While the mysterious nature of Aster alpinus var. serpentimontanus might intrigue plant collectors and botanical enthusiasts, the lack of available growing information makes it a challenging choice for most gardeners. Until more research sheds light on this variety’s characteristics and requirements, you might be better served by choosing well-documented native plants that offer similar aesthetic appeal with proven garden performance.

Sometimes in gardening, as in life, the most mysterious options aren’t necessarily the most practical ones. But who knows? Perhaps future botanical research will unlock the secrets of this elusive alpine aster variety.
