Seventop Turnip (Brassica septiceps): Unraveling a Garden Mystery
If you’ve stumbled across the name seventop turnip or its scientific name Brassica septiceps in your gardening research, you might be scratching your head trying to find more information about this elusive plant. Well, you’re not alone – and there’s a good reason why details are hard to come by!
The Name Game: What’s in a Scientific Name?
Here’s where things get a bit puzzling. While Brassica septiceps appears in some older references with the synonym Brassica rapa L. var. septiceps L.H. Bailey, this specific scientific name isn’t recognized in current botanical databases as a valid, distinct species. This is actually more common than you might think in the plant world – names change, classifications get updated, and sometimes old names fall out of use.
The Brassica Family Connection
What we do know is that this name is connected to the Brassica family, which includes familiar garden favorites like:
- Turnips
- Mustards
- Cabbage
- Kale
- Radishes
The reference to it being a variety of Brassica rapa suggests it’s related to field mustard or turnip, but without clear taxonomic verification, it’s difficult to provide specific growing advice.
What This Means for Your Garden
If you’re interested in growing what’s been called seventop turnip, your best bet is to look for verified varieties of Brassica rapa or other well-documented turnip varieties. These plants are typically:
- Cool-season crops that prefer spring and fall growing
- Fast-growing annuals
- Adaptable to various soil conditions
- Beneficial for pollinators when allowed to flower
A Word of Caution
Since we can’t verify the native status, invasive potential, or specific characteristics of Brassica septiceps, it’s wise to be cautious. Many Brassica species can self-seed readily and some have become weedy in certain areas.
Better Alternatives
Instead of hunting for this mysterious plant, consider these well-documented and readily available options:
- Purple Top Turnip – A classic, reliable variety
- Hakurei Turnips – Sweet and quick-growing
- Native mustards – Check with your local native plant society for species native to your area
The Bottom Line
While the name Brassica septiceps or seventop turnip might appear in some gardening references, the lack of current taxonomic recognition makes it difficult to recommend for home gardens. When in doubt, stick with well-documented plant varieties from reputable sources, and always consider native alternatives that will support your local ecosystem.
Remember, successful gardening often comes down to choosing the right plants for your specific location and conditions – and that’s much easier to do when you’re working with plants that have clear, verified information available!
