Whether you want vibrant flowers, climbing vines, privacy plants, or dramatic foliage, these speedy growers can transform your outdoor space in just one season.

Here are 14 fast growing plants that can thrive in a variety of gardens and climates.

1. Bamboo

Bamboo is one of the fastest-growing plants in the world, making it an excellent choice for creating privacy screens or tropical-style landscapes. Many varieties can grow several feet in a single season. Clumping bamboo types are ideal for home gardens because they spread more slowly and are easier to control.

Bamboo prefers full sun to partial shade and thrives in moist, well-drained soil.

2. Morning Glory

Morning Glory vines quickly climb fences, trellises, and garden arches while producing beautiful trumpet-shaped flowers in shades of blue, purple, pink, and white. These annual vines can grow rapidly during warm weather and attract pollinators throughout the summer.

Plant Morning Glory seeds in full sun for the best blooms.

3. Sunflower

Sunflowers are a favorite among gardeners because they grow quickly from seed and produce massive cheerful blooms. Some varieties can reach heights of 10 feet or more in a single growing season.

Sunflowers thrive in sunny locations with rich, well-drained soil and are excellent for attracting bees and birds.

4. Black-Eyed Susan

Black-Eyed Susans are hardy, drought-tolerant flowers known for their golden-yellow petals and dark centers. These fast-growing perennials bloom throughout summer and spread easily to fill garden beds with color.

They grow best in full sun and adapt well to many soil types.

5. English Ivy

English Ivy is a fast-growing evergreen vine commonly used to cover walls, fences, and ground areas. Its dense foliage creates a classic look while helping reduce erosion on slopes and difficult spaces.

This plant grows well in shade or partial sun and tolerates a wide range of conditions.

6. Nasturtium

Nasturtiums are colorful annual flowers that grow quickly and produce edible blooms and leaves. Their trailing growth habit makes them ideal for hanging baskets, containers, or garden borders.

They prefer full sun and relatively poor soil, which encourages more flowers and fewer leaves.

7. Sweet Pea

Sweet Peas are fragrant climbing flowers that grow rapidly in cool weather. Their delicate blossoms add beauty and a sweet scent to trellises and fences during spring and early summer.

For best results, plant Sweet Pea seeds in full sun with rich, well-drained soil.

These flowers perform best in full sun with regular watering.

Cosmos are airy, elegant flowers that grow rapidly and bloom continuously throughout summer. They are excellent for cottage gardens, pollinator gardens, and cut flower arrangements.

Cosmos tolerate poor soil and drought conditions surprisingly well.

11. Privet

Privet is a fast-growing shrub commonly used for hedges and privacy screens. With regular trimming, it forms a dense green barrier that can quickly define garden spaces and property lines.

Privet grows best in full sun to partial shade and adapts to most soils.
