Top 6 Quick Growing Flower Seeds for Instant Color
If you’re ready to transform your garden with fast results, here are six of the best quick growing flower seeds that deliver stunning blooms in record time.
1. Zinnias (Zinnia elegans)
Zinnias are a favorite among gardeners for their bold colors, long blooming period, and ease of growth. From seed to flower, they take just 6–8 weeks. They come in a rainbow of shades—red, pink, orange, yellow, and purple—and their daisy-like blooms attract butterflies all season long. Zinnias thrive in full sun and well-drained soil, making them ideal for garden beds and cutting gardens.
2. Marigolds (Tagetes spp.)
Marigolds are not only quick to grow (7–10 weeks) but also naturally pest-resistant, helping to deter nematodes and other garden pests. Their bright orange and yellow flowers add cheerful contrast to any landscape. They’re perfect for borders, containers, and companion planting with vegetables. Plus, they’re incredibly low maintenance—just plant, water, and enjoy.
3. Sunflowers (Helianthus annuus)
Sunflowers are iconic for their towering stems and massive blooms, and many varieties grow from seed to flower in just 8–10 weeks. Dwarf types are great for small spaces, while giant varieties can reach over 10 feet tall. They love full sun and are a hit with birds and pollinators. Plant them along fences or at the back of garden beds for a dramatic effect.
4. Nasturtiums (Tropaeolum majus)
Nasturtiums are not only fast bloomers (5–7 weeks) but also edible! Their peppery leaves and vibrant orange, red, and yellow flowers can be tossed into salads or used as garnishes. They grow well in poor soil and full sun, making them perfect for beginners. Plus, they attract beneficial insects and help repel aphids.
5. Cosmos (Cosmos bipinnatus)
Cosmos are delicate-looking but tough plants that bloom in just 7–10 weeks. Their feathery foliage and pink, white, or purple blooms sway gracefully in the breeze. They’re drought-tolerant and thrive in hot, sunny spots. Cosmos are excellent for wildflower meadows, cottage gardens, and attracting pollinators.
6. Calendula (Calendula officinalis)
Often called “pot marigold,” calendula blooms in 6–8 weeks and offers cheerful orange and yellow flowers. Beyond their beauty, calendula petals are used in natural skincare and herbal remedies. They prefer cooler weather and partial to full sun, making them ideal for spring and fall planting.
How to Plant and Care for Quick Growing Flowers
Getting the most out of your quick growing flower seeds starts with proper planting and care. The good news? These varieties are generally low-maintenance, but a few simple steps can boost your success.
When to Plant
Most quick growing flower seeds should be sown after the last frost date in your area. Check your local frost dates and aim to plant in spring when soil temperatures reach at least 60°F (15°C). In warmer climates, you can also plant in early fall for a late-season bloom.
Soil and Sunlight Needs
While many fast bloomers are adaptable, they all thrive in well-drained soil and full sun (6+ hours of direct sunlight per day). Prepare your garden bed by loosening the soil and removing weeds. For containers, use a high-quality potting mix and ensure proper drainage.
Planting Tips
- Direct sow when possible: Many quick bloomers, like zinnias and sunflowers, don’t transplant well. Plant seeds directly in the ground.
- Follow seed packet instructions: Pay attention to planting depth and spacing to avoid overcrowding.
- Water gently after planting: Keep the soil moist but not soggy until seeds germinate.
- Thin seedlings: Once seedlings are a few inches tall, thin them to the recommended spacing to allow room for growth.
Ongoing Care
Once established, most quick growing flowers need minimal care. Water during dry spells, but avoid overwatering. Deadhead spent blooms to encourage more flowers. A light application of balanced fertilizer at planting time is usually enough—these plants don’t need heavy feeding.
Design Ideas for Using Fast-Blooming Flowers
Quick growing flower seeds aren’t just practical—they’re also versatile design elements. Here’s how to use them creatively in your garden.
Create a Rainbow Border
Plant a mix of zinnias, marigolds, and cosmos in a curved border along a walkway or garden edge. Group colors by hue for a gradient effect or mix them for a joyful, cottage-garden look.
Brighten Containers and Window Boxes
Use nasturtiums, dwarf sunflowers, and calendula in pots on patios, balconies, or near entryways. Combine with herbs like basil or thyme for a fragrant, edible display.
Fill in Bare Spots
Have a patchy area in your lawn or garden? Scatter a mix of quick bloomers like cosmos and marigolds to cover the space with color in just a few weeks.
Start a Cutting Garden
Zinnias and sunflowers are excellent for bouquets. Dedicate a small section of your garden to growing flowers you can snip and bring indoors. Harvest in the morning when blooms are fresh.
Tips for Succession Planting and Extended Blooms
One of the best ways to keep your garden colorful all season is through succession planting. Instead of sowing all your seeds at once, plant small batches every 2–3 weeks. This ensures that as one group of flowers finishes blooming, another is just starting.
For example, plant zinnias in early May, then again in late May and mid-June. This staggered approach keeps your garden vibrant from summer through fall. It’s especially effective in regions with long growing seasons.
You can also combine early, mid, and late-season bloomers. Start with fast growers like nasturtiums, add mid-season cosmos, and finish with late-blooming sunflowers. This creates a dynamic, ever-changing landscape.
Conclusion
Quick growing flower seeds are a game-changer for anyone who wants instant garden color without the wait. From cheerful marigolds to towering sunflowers, these fast-blooming varieties bring joy, beauty, and ecological benefits in just a few short weeks. Whether you’re gardening with kids, sprucing up a small space, or simply craving a splash of color, these seeds deliver reliable, rewarding results.
With minimal effort and maximum impact, quick growing flower seeds prove that you don’t need to wait months to enjoy a blooming paradise. So grab your trowel, pick your favorites, and get planting—your garden (and your soul) will thank you.
