Apologies to all Seed Needs shoppers. At this time we just aren't able to operate sufficiently. We have no choice but to close our online shop until we have successfully relocated. We tried to open up to orders this past weekend (Jan 17th, 2021) but are just not able to keep up with the lack of space and organization. We are not accepting orders at this time and as that you visit to search for a vast majority of our products. We thank you all for your patience through these crazy times. Your continued business means the world to us. Thank you.

Grow a garden filled with Salt N’ Roast, Mammoth Sunflowers from freshly harvested Helianthus annuus flower seeds. This mammoth sunflower is a hybrid variety that offers delicious, plump, sunflower seeds. The huge, mammoth sunflower heads grow to a massive size and are surrounded by bright yellow petals. The plants themselves reach a mature height of 4 to 6 feet tall. It is best to space these sunflowers about 2 to 3 feet apart, allowing them to reach their full potential.

Grown as an annual flowering plant, Salt N’ Roast, Mammoth Sunflower will grow quickly, bloom profusely and later die with the first killing frost. Sunflowers are best grown as a border plant, along fences, or in masses. For a gorgeous blend of colors, browse our large selection of Sunflowers from our Sunflower category.

Sowing The Seed

Sunflowers are not particularly fond of being transplanted, but if started indoors, sow in peat pots, 6 to 8 weeks prior to the last frost. Sow at a depth of 1” under topsoil. Transplant entire pots into the garden, or direct sow when the weather is warm and all danger of frost has passed. Stakes may be necessary to support your Sunflowers, only until the stems become stronger enough to stand on their own.

Growing Conditions

Sunflowers grow long taproots and may rot if the roots become waterlogged. It is recommended to check your sowing area for hard, compacted soil prior to sowing. Renew any hard, compacted soil with a mixture of compost. Sunflowers will enjoy an area of full sunlight for the majority of the day and should be watered daily so that the soil is kept moist until germination has occurred.

Germination & Growth

Your sunflower seeds will begin to germinate within 7 to 10 days after sowing. Plants will grow to a mature height of 4 to 6 feet tall. Space your seeds about 18 to 24 inches apart from one another. Salt N’ Roast, Mammoth Sunflower produces beautiful yellow blooms with huge centers, offering hundreds of plump, delicious Sunflower seeds to roast and enjoy.
