Secund Jewelflower: A Rare California Native Worth Knowing About
Meet the secund jewelflower (Streptanthus glandulosus secundus), one of California’s lesser-known botanical treasures. This annual wildflower might not be a household name, but for native plant enthusiasts interested in rare and specialized species, it represents something quite special in the Golden State’s diverse flora.
What Makes Secund Jewelflower Special?
The secund jewelflower is an annual forb, meaning it’s a non-woody flowering plant that completes its entire life cycle in just one growing season. As a member of the mustard family, it shares characteristics with more familiar garden plants, but its beauty lies in its delicate, specialized nature.
This plant is exclusively native to California, making it a true Golden State endemic. Its limited distribution adds to its charm for collectors of rare native plants, though it also means you won’t find it growing wild just anywhere.
A Word About Rarity
Here’s something important to know: secund jewelflower has a conservation status that suggests it may be uncommon or of special concern. If you’re interested in growing this plant, it’s crucial to source seeds or plants only from reputable native plant nurseries that practice ethical collection methods. Never collect from wild populations.
Garden Appeal and Growing Conditions
Like many California natives, secund jewelflower likely thrives in well-draining soils and can handle the state’s Mediterranean climate patterns. As an annual, it would fit beautifully into:
- Specialized native plant gardens
- Wildflower meadow plantings
- Educational or demonstration gardens featuring rare California flora
- Rock gardens with good drainage
The plant probably does best in USDA hardiness zones 8-10, matching California’s climate zones where it naturally occurs.
Wildlife and Pollinator Benefits
While specific research on this subspecies is limited, jewelflowers generally support native pollinators, particularly smaller native bees and beneficial insects. By growing rare natives like secund jewelflower, you’re contributing to habitat preservation and supporting the intricate web of relationships between California’s native plants and wildlife.
Should You Grow Secund Jewelflower?
This plant is perfect for the dedicated native plant gardener who:
- Appreciates rare and unusual species
- Wants to support conservation efforts
- Enjoys the challenge of growing specialized plants
- Has experience with California native annuals
However, it might not be the best choice if you’re looking for a showy, low-maintenance garden centerpiece or if you’re just starting your native plant journey.
Growing Tips and Care
Since detailed cultivation information for this specific subspecies is limited, here are some general guidelines based on related California native annuals:
- Plant seeds in fall for spring germination
- Provide excellent drainage
- Avoid summer water once established
- Allow plants to self-seed for natural propagation
- Choose a sunny to partially shaded location
The Bottom Line
Secund jewelflower represents the fascinating diversity found within California’s native flora. While it may not be the easiest or most dramatic plant for your garden, it offers something special: a connection to the state’s unique botanical heritage and an opportunity to participate in conservation through cultivation.
If you decide to grow this rare beauty, remember to source it responsibly and consider it a privilege to help preserve a piece of California’s natural legacy right in your own backyard.
