These eye-catching flowers can grow up to six inches tall, but with the right conditions, they can even reach up to 12 inches in height.

The best thing about speedwell is that its upright flowers are spiked, making them an excellent choice for garden borders. They also love full sunlight and thrive in well-drained soil with plenty of water. Now, let’s talk about another incredible perennial plant called Shrubby Cinquefoil, which is also known as Potentilla fruticosa.

To keep them looking vibrant, they require soil that can retain moisture, and regular watering is critical. Whether you choose to plant them in a garden bed or as a border plant for your sunlit areas, the decision ultimately lies with you.

5. Pennisetum or Fountain Grass


Fountain grass is a popular choice for garden borders thanks to its eye-catching mounds of blades that spray outwards in all directions.

Shasta daisies boast an iconic summer look and make for easy-to-care-for perennials that are perfect for filling up empty spaces or defining sunny borders.

The butterfly bush is a stunning shrub that grows rapidly and produces an abundance of small, colorful flowers. It’s perfect for planting as a border plant, especially in areas with full sunlight. However, it requires a lot of attention to flourish. These plants need lots of sun, nutrient-rich soil that drains well, and regular watering. Additionally, they require ample space to grow to their full potential. As a result, the butterfly bush is considered a high-maintenance shrub.



The coreopsis plant is an excellent choice for those who want a low-maintenance, drought-resistant flower that looks fantastic in sunny borders.

To thrive, this plant requires full sun exposure and well-draining soil with good loam quality, so it’s important to keep this in mind while planning your garden. Despite its need for proper drainage, the coreopsis should be watered regularly, especially when growing in the spring season, as it grows between 1.5 to four feet tall.
