6 Best Fast-Growing Grow Plants for Your Garden

Want a lush, green garden in a hurry? Fast-growing plants are the perfect solution for gardeners who crave quick results without waiting seasons for growth. Whether you’re planting for privacy, color, or fresh produce, these rapid growers will bring your space to life in no time. Here are six of the best fast-growing plants to add vitality, beauty, and utility to your garden.

1. Sunflowers (Helianthus annuus)

Sunflowers are one of the fastest-growing annuals, often reaching maturity in just 70–90 days. Their large, golden blooms not only add cheer to any garden but also attract pollinators like bees and butterflies. These plants love full sun and well-draining soil. Once they sprout, they shoot up rapidly, sometimes growing several inches a day under the right conditions. Beyond their beauty, sunflower seeds can be harvested for snacks or bird feed, making them a rewarding and multi-purpose garden choice.

2. Zucchini (Cucurbita pepo)

If you’re looking for a productive vegetable that’s fast to grow, zucchini is a must-have. Zucchini plants typically start producing fruit within 40–50 days from planting. They’re prolific producers, thriving in warm conditions and full sun. Zucchini also has large leaves and yellow blossoms that create an attractive display in vegetable gardens. Regular harvesting encourages more fruit production, so you can enjoy multiple rounds of delicious zucchinis throughout the growing season.

3. Nasturtiums (Tropaeolum majus)

These cheerful annual flowers germinate quickly—often within 7–10 days—and start blooming in just a few weeks. Nasturtiums are perfect for filling in bare garden spots with rich green foliage and bright red, yellow, or orange blooms. They’re also edible, adding a peppery flavor to salads and garnishes. Plus, their trailing or bushy habit makes them perfect for borders, containers, or hanging baskets. As a bonus, nasturtiums can help deter pests like aphids, making them an eco-friendly garden ally.

4. Bamboo (Phyllostachys spp.)

While bamboo needs to be planted thoughtfully due to its aggressive spreading nature, it’s unmatched in fast growth. Some species can grow over 3 feet per day! Ideal for creating a natural privacy screen or lush, exotic backdrop, bamboo thrives in full sun to partial shade and prefers moist, well-draining soil. Opt for clumping bamboo varieties if you want less invasive growth. With proper maintenance, bamboo can be a stunning and dynamic addition to your garden.

5. Sweet Alyssum (Lobularia maritima)

Sweet alyssum is a charming groundcover known for its rapid growth and cloud-like clusters of white, pink, or purple flowers. Germination occurs in just 5–7 days, and it can begin blooming in less than 6 weeks. This plant thrives in cool to moderate climates and does best in full sun to partial shade. It not only adds color and fragrance but also attracts pollinators, helping to support the ecosystem in your garden. It’s ideal for borders, containers, or rock gardens.

6. Radishes (Raphanus sativus)

For lightning-fast results in the vegetable garden, radishes are unbeatable. Some varieties mature in as little as 3 weeks! They are incredibly easy to grow from seed and can be planted multiple times throughout the growing season for a steady harvest. Radishes do well in cooler weather and need consistent moisture for the best flavor and texture. Whether you’re an experienced gardener or a beginner, radishes are a satisfying, no-fuss addition to your edible garden.
