Tulips

Mammoth Red Rock Cabbage HeirloomMassive, vibrant red heads that wow gardeners and chefs—perfect for kraut, slaw, and stunning market displays! 🌱🧄💜 Variety Overview Mammoth Red Rock (Brassica oleracea var. capitata) produces gigantic 10-15 lb heads (10-12" diameter) with deep crimson-purple leaves, dense solid cores, and a mild, crisp, sweet flavorideal for fresh salads, fermentation, roasting, or storage. This cold-hardy beauty thrives in cool weather, resists splitting, and adds bold color to your harvest! Origin & History Developed in the late 1800s by American breeders, first introduced commercially in 1889 by J.H. Gregory & Son Seed Company (Marblehead, Massachusetts, USA). A selected strain from early European red cabbages adapted for North American gardens; prized for size since Victorian-era catalogs. Preserved by Seed Savers Exchange (SSE) since the 1970s— a true heirloom survivor that's outgrown modern hybrids in flavor and stature. Detailed Planting Instructions Grow epic heads with these foolproof steps: Timing: Cool-season crop—sow indoors 4-6 weeks before last spring frost (or direct sow fall for overwintering in mild zones 7+). Best in zones 3-9. Soil Prep: Fertile, well-drained loam with pH 6.5-7.5. Amend with compost/manure; full sun (6+ hours). Sowing: Plant seeds ¼-½" deep, 2" apart in trays. Keep at 70-75°F days/60°F nights; thin to strongest seedlings. Harden off 7-10 days. Transplanting: Set out 18-24" apart in rows 30-36" apart when 4-6" tall (soil 45-50°F). Bury stems to first leaves for stability. Care: Water deeply (1-1.5"/week); mulch heavily. Fertilize with nitrogen-rich (e.g., fish emulsion) every 3 weeks. Use row covers for cabbage worms/fleas; rotate crops. Harvest: 85-100 days; cut heads at base when firm/full-sized. Store cool (32-40°F)/humid up to 4-6 months. Trait Details Type Heirloom red storage cabbage Days to Maturity 85-100 days from transplant Head Size/Yield 10-15 lbs/head; 1-2 heads/plant Storage Excellent (4-6 months); color deepens Pests/Disease Bolt-resistant; watch for clubroot—use clean seed Special Notes Cold-tolerant to 20°F; great for sauerkraut! "One plant, one monster head—Firefly Farm's Mammoth Red Rock delivers garden legends!" Stock your Firefly Farm & Mercantile shelves with this customer-stunner—plant success guaranteed! 💜🧅 Nutrient Powerhouse Overview Red cabbage (Brassica oleracea var. capitata f. rubra) outshines green varieties in antioxidants due to its vibrant anthocyanins (red pigments). Just 1 cup raw (89g) provides: Vitamin C: 85% DV (immune boost, collagen production). Vitamin K: 68% DV (bone health, blood clotting). Fiber: 9% DV (gut health, satiety). Plus folate, potassium, manganese, and sulforaphane (cancer-fighting compound). Heirloom varieties shine brighter: Less selective breeding preserves higher phytonutrient diversity, leading to amplified antioxidants (up to 20-30% more anthocyanins per studies on open-pollinated brassicas). Key Health Benefits Antioxidant & Anti-Inflammatory: Anthocyanins combat oxidative stress, reducing chronic disease risk (e.g., heart disease by 32% per meta-analyses). Heart Health: Lowers LDL cholesterol, blood pressure; potassium balances sodium. Cancer Prevention: Glucosinolates/sulforaphane detoxify carcinogens; lab studies show 50% tumor growth inhibition. Digestive & Weight Support: Fermentable fiber feeds gut microbiome; low-cal (28 kcal/cup) aids weight loss. Immune & Skin Boost: Vitamin C enhances white blood cells; protects against UV damage. Brain & Bone Health: Vitamin K prevents cognitive decline; supports calcium absorption. Nutrient/Benefit Amount per Cup (Raw) % Daily Value Heirloom Edge Anthocyanins 100-200mg N/A Higher diversity vs. hybrids Vitamin C 51mg 85% Enhanced bioavailability Vitamin K 38mcg 68% Optimal for non-fortified diets Fiber 2.2g 9% Prebiotic boost for probiotics Sulforaphane Varies N/A Peaks in fresh/heirloom cuts "Heirloom red cabbage isn't just food—it's functional medicine from your backyard.

<li>Use of Computer Tracking Technologies.</li>
<ol>
<li>No Tracking of Personal Information.&nbsp;The Site is not set up to track, collect or distribute personal information not entered by visitors.

Customer can set its browser to notify customer before a cookie is received, giving an opportunity to decide whether to accept the cookie. Customer may also set its browser to turn off cookies; however, some websites may not then work properly.</li>

Web beacons usually work in conjunction with cookies. If customer does not want cookie information to be associated with customer's visits to these pages, customer can set its browser to turn off cookies; however, web beacon and other technologies will still detect visits to these pages, but the notices they generate cannot be associated with other non-identifiable cookie information and are disregarded.</li>
<li>Collection of Non-Identifiable Information.&nbsp;The Company may collect non-identifiable information from user visits to the Site in order to provide better customer service. Examples of such collecting include: traffic analysis, such as tracking of the domains from which users visit, or tracking numbers of visitors; measuring visitor activity on the Site; website and system administration; user analysis; and business decision making. Such information is sometimes known as "clickstream data." We or our contractors may use this data to analyze trends and statistics.</li>
<li>Collection of Personal Information.&nbsp;The Company collects personal identifying information from customer during a transaction. We may extract some personally identifying information about that transaction in a non-identifiable format and combine it with other non-identifiable information, such as clickstream data.

</ol>
<li>Information Security.</li>
<ol>
<li>No Liability for Acts of Third Parties.&nbsp;&nbsp;The Company will exercise all reasonable efforts to safeguard the confidentiality of customer personal information.

PRIVACY POLICY

If for any reason you are not happy with a purchase, please email us at andre@fireflyfarmandmercantile.com so we can assist.&nbsp; We do provide refunds up to 10 days of you receiving merchandise. We may ask for the product to be returned to be eligible for a refund. We do not do refunds for shipping unless it is something we feel we could have done better. Carriers often don’t deliver based on their own timelines but you can always pick up at our garden shop too. Unlike most online garden retailers we have a business location too, so come in out and visit our farm.

REFUND POLICY

Sometimes the products purchased may weigh more or less than the calculated shipping rate. We try our best to determine the weights based on current and past inventory.&nbsp; We do provide refunds proactively and will communicate accordingly. And in some instances we may need to contact you for additional payment if the shipping warrants it.&nbsp;
We try our best to offer the right services for you at checkout. If we see an opportunity for a more desirable service we will reach out to you. Please ensure we have a good contact number or email&nbsp; so we can do so.&nbsp;
United States Postal Service and UPS services go out Monday through Friday. This allows us to ensure we provide a quality product at a reasonable rate. Any delivery times are just estimates from the carrier once they receive the package. We cannot change this due to Shopify’s policy. I would if I could as it can lead to some confusion. We are a small garden shop and have very little pull with any carrier (and seriously who really does with USPS or any other). For the most part UPS timelines have been the most consistent. But there are not delivery dates but days your package will be in transit once we drop it off. In average we take 1-4 business days to fulfill orders and then the carrier’s approximate shipping times are added to that.&nbsp;

SHIPPING POLICY

We accept various forms for payment. Currently we accept Visa, Mastercard, Discover, and American Express as well as Google Pay and Shop Pay.
We strive to deliver on what we say we are going to do. Pre-orders are orders that are being taken without inventory on hand. The advantage is you get a great price, but sometimes crops just don't yield what is expected. We will use many different suppliers to fulfill your orders as best as possible. We won't substitute without your permission so please make sure you leave your best contact information so we can reach out to you. On occasion if unable to reach you, we will simply send the substitute product but you are welcome to call us once receiving it and letting us know you’d like a refund on it.
