Blood Currant: A Rare California Native Worth Seeking Out

If you’re a California native plant enthusiast looking for something truly special, blood currant (Ribes sanguineum var. deductum) might just be the unique shrub you’ve been searching for. This perennial woody plant represents a fascinating piece of California’s botanical heritage, though finding reliable information about this particular variety can be as challenging as locating the plant itself.

What Makes Blood Currant Special

Blood currant is a multi-stemmed shrub that typically grows to a manageable size of 13-16 feet in height, making it a substantial but not overwhelming presence in the garden. As a member of the currant family, it shares DNA with the more commonly known red flowering currant, but this particular variety has carved out its own niche in California’s diverse plant communities.

The plant is also known by its scientific synonym Ribes deductum Greene, a name you might encounter in older botanical literature or specialized native plant resources.

Where Blood Currant Calls Home

This shrub is a true California native, found exclusively within the Golden State’s borders. Its limited distribution makes it a genuine regional specialty – like finding a rare vintage wine that’s only produced in one small vineyard.

A Word of Caution: Rarity Matters

Here’s where things get interesting (and important): blood currant has a Global Conservation Status of S5T2T3Q, which suggests this variety may be quite uncommon in the wild. While the exact meaning of this particular ranking isn’t clearly defined, the T2T3 portion typically indicates a plant that ranges from imperiled to vulnerable.

What does this mean for you as a gardener? If you’re lucky enough to find blood currant available, make absolutely sure you’re purchasing from a reputable nursery that sources their plants responsibly. Never collect plants from the wild, and always verify that any nursery stock comes from ethically propagated sources.

The Challenge of Growing Blood Currant

If you’re expecting a detailed growing guide here, I have to be honest with you – reliable cultivation information for this specific variety is surprisingly scarce. This isn’t uncommon with rare native varieties that haven’t made their way into mainstream horticulture.

What we do know is that as a perennial shrub, blood currant is built for the long haul once established. Its multi-stemmed growth habit suggests it could work well as:

  • A specimen plant in native gardens
  • Part of a California native plant collection
  • A conversation starter for serious native plant enthusiasts

Why Consider Blood Currant Despite the Unknowns?

You might wonder why anyone would want to grow a plant with so many question marks surrounding it. Here’s the thing – every native plant in your garden is a small act of conservation. By growing rare California natives like blood currant, you’re:

  • Preserving genetic diversity
  • Supporting specialized native plant nurseries
  • Creating habitat that might benefit local wildlife (even if we don’t have specific data on which creatures blood currant supports)
  • Becoming part of a community of gardeners who value botanical rarity and regional authenticity

The Bottom Line

Blood currant isn’t for every gardener or every garden. It’s for the native plant collectors, the conservation-minded gardeners, and those who find beauty in California’s lesser-known botanical treasures. If you do decide to seek out this rare variety, approach it with respect for its scarcity and commitment to responsible sourcing.

Sometimes the most rewarding plants in our gardens are the ones that ask more questions than they answer – and blood currant is definitely one of those intriguing characters.
