Seed Needs Cherry Rose Bi-Color Sunflower Seeds
- Quality Sunflower seeds packaged by Seed Needs. Intended for the current and the following growing season. Packets are 3.25" wide by 4.50" tall and come with a full colored illustration on the front side, as well as detailed sowing instructions on the reverse.
- All seeds by Seed Needs are Non-GMO based seed products
- 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 1/2” under topsoil.

Stakes may be necessary to support your Sunflowers, only until the stems become strong enough to stand on their own.
- 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.
- All Sunflower seeds sold by Seed Needs are Non-GMO based seed products and are intended for the current & the following growing season. All seeds are produced from open pollinated plants, stored in a temperature controlled facility and constantly moved out due to popularity.

A Guide to Selecting the Best Sunflower Seeds
Identify Your Primary Purpose
The most critical decision factor is determining why you are planting. Sunflower varieties are generally categorized into three functional groups. First, there are Giant/Agricultural varieties, which are bred for high oil content or massive seed production. These are ideal if you intend to harvest the seeds for snacking or birdseed. Second, you have Ornamental/Branching varieties. These are bred for aesthetics, often featuring multiple blooms on a single stalk, making them perfect for cutting and floral arrangements. Finally, there are Dwarf varieties, which are essential for container gardening, small balconies, or creating borders that don't overshadow your other perennials. Mixing these up—such as planting a ten-foot giant in a small pot—is a common beginner mistake.
Evaluate Seed Type: Single vs. Multi-Bloom
When browsing seed packets, pay close attention to the growth habit. Single-stem sunflowers produce one massive, dramatic flower head on a single stalk. These are high-impact and great for focal points. However, branching sunflowers produce a main stem that splits into several smaller stalks, each bearing flowers. While branching types may not have the singular 'wow' factor of a giant head, they provide a much longer blooming season and more total flowers per plant. If your goal is a continuous supply of cut flowers for your home, prioritize branching cultivars.
Check Germination Rates and Purity
Not all seeds are created equal. High-quality seed suppliers will clearly list the germination percentage on the packaging. Look for seeds with a germination rate of 85% or higher. A lower rate means you will have to plant significantly more seeds to achieve the desired density, which can lead to overcrowding and competition for nutrients. Additionally, look for 'uncoated' or 'pure' seed descriptions if you are growing for consumption. Some seeds are treated with fungicides to prevent soil-borne diseases. While this is helpful for commercial farming, it is an unnecessary chemical addition if you are growing a small home garden for edible use.
Consider Climate and Growing Season
Sunflowers are heat-loving plants, but different varieties have varying tolerances. Some giant varieties require a very long, warm growing season to reach their full potential. If you live in a region with a shorter summer, look for 'early maturing' varieties that can reach bloom before the first frost. Furthermore, consider the soil requirements. While sunflowers are famously hardy, some varieties are more prone to powdery mildew in humid climates, while others are more drought-tolerant. Matching the variety to your specific microclimate is the difference between a struggling plant and a thriving sunflower forest.
Summary of Recommendation Logic
To choose the best seeds, follow this logic: If you want to eat them, choose high-oil agricultural varieties. If you want a beautiful bouquet, choose branching ornamental varieties. If you have limited space, choose dwarf cultivars. Always prioritize seeds with high germination percentages and ensure the maturity timeline aligns with your local frost dates.
