1. Forget-Me-Nots (Myosotis sylvatica)

As their name suggests, these charming flowers are truly unforgettable. They produce clouds of tiny, sky-blue flowers with sunny yellow centers in the spring. They are perfect for woodland gardens and will happily self-seed to create a natural, flowing carpet of blue.

  • Best For: Shady borders, naturalizing under trees.
  • Pro Tip: They love moist soil. Don’t let them dry out completely, especially during their blooming period.

2. Lobelia (Lobelia erinus)

A classic for a reason! Trailing lobelia is a superstar for hanging baskets and container edges, spilling over with a profusion of intense blue flowers. It blooms tirelessly from spring until the first frost. Don’t worry—these flowers are perfect for beginners!

  • Best For: Containers, window boxes, and hanging baskets.
  • Pro Tip: Lobelia can fizzle out in intense mid-summer heat. Give it a good trim (about a third of its growth) and it will often bounce back for a fall flush.

3. Blue Star Creeper (Isotoma fluviatilis)

If you need a tough, beautiful groundcover, look no further. This low-growing plant forms a dense mat of green foliage dotted with star-shaped, pale blue flowers. It can even handle light foot traffic, making it a fantastic lawn alternative or a filler between paving stones.

  • Best For: Groundcover, planting between pavers, rock gardens.
  • Pro Tip: It spreads readily, so plant it where you want it to fill in. It’s a living mulch!

4. Grape Hyacinth (Muscari armeniacum)

One of the first signs of spring, these delightful bulbs produce dense clusters of small, bell-shaped flowers that look like tiny bunches of grapes. They are incredibly easy to grow and will multiply over the years, creating a stunning blue carpet.

  • Best For: Borders, forcing indoors, planting in drifts.
  • Pro Tip: Plant the bulbs in the fall for a spectacular spring show. Plant them in large groups for the best visual impact.

5. Brunnera (Brunnera macrophylla)

Also known as Siberian Bugloss, Brunnera is a shade-garden champion. It produces airy sprays of tiny, intense blue flowers that float above its beautiful heart-shaped leaves. Varieties like ‘Jack Frost’ have stunning silver foliage that provides interest all season long.

7. Lithodora ‘Grace Ward’ (Lithodora diffusa)

For a truly electric, gentian-blue color, nothing beats Lithodora. This low-growing, shrubby perennial is covered in masses of brilliant blue, star-shaped flowers in late spring and early summer. It’s a real showstopper!

  • Best For: Rock gardens, cascading over walls, sunny and dry spots.
  • Pro Tip: This plant demands well-draining, acidic soil. If you have alkaline soil, it’s best grown in a container with ericaceous compost.

8. Plumbago (Ceratostigma plumbaginoides)

An excellent groundcover for late-season color. Plumbago, or Leadwort, produces vivid cobalt-blue flowers from late summer into fall. As a bonus, its green leaves turn a stunning bronze-red in autumn, providing a double dose of color.

  • Best For: Groundcover in sun or part shade, fall interest.

    • * Pro Tip: It can be slow to emerge in the spring, so be patient! Mark its location so you don’t accidentally dig it up.

9. Flax (Linum perenne)

With delicate, sky-blue flowers that seem to dance on wiry stems, Blue Flax adds a touch of wild, airy grace to the garden. Each flower only lasts a day, but the plant produces so many that it remains in bloom for weeks. It’s one of the best sustainable plants with small blue flowers for dry areas.

  • Best For: Meadow gardens, cottage gardens, dry and sunny spots.
  • Pro Tip: Flax does not like to be moved, so choose its permanent home carefully. It thrives on a bit of neglect.

10. Baby Blue Eyes (Nemophila menziesii)

This charming annual is as sweet as its name. It forms low mounds of feathery foliage and is covered in upward-facing, bowl-shaped flowers of a clear, sky blue, often with a white center. It’s fantastic for filling in gaps and blooms quickly from seed.

  • Best For: Edging paths, containers, wildflower gardens.
  • Pro Tip: Sow seeds directly in the garden in early spring (or fall in mild climates). They prefer cooler weather.

11. Creeping Phlox (Phlox subulata ‘Emerald Blue’)

A springtime spectacle, Creeping Phlox forms a dense mat of needle-like foliage that becomes completely smothered in tiny lavender-blue flowers. It’s perfect for cascading over rock walls or as a weed-suppressing groundcover in full sun.

  • Best For: Slopes, rock walls, sunny groundcover.
  • Pro Tip: After flowering, give it a light shear to encourage dense growth and prevent it from becoming leggy.

12. Scabiosa (Scabiosa columbaria ‘Butterfly Blue’)

Known as the Pincushion Flower, ‘Butterfly Blue’ produces lovely lavender-blue flowers on long, wiry stems for an incredibly long season—from spring to frost! The “pins” in the cushion are attractive to all sorts of pollinators.

The Ultimate Plants with Small Blue Flowers Care Guide

You’ve picked your favorites, now what? Don’t worry, caring for these beauties is straightforward. Following these plants with small blue flowers best practices will ensure a garden filled with vibrant color.

Getting the Soil Just Right

Most of these plants aren’t overly fussy, but they almost all share one critical need: well-draining soil. Waterlogged roots are the number one enemy! Before planting, amend heavy clay soil with compost or grit to improve its structure. For containers, always use a quality potting mix.

Sunlight: Finding the Sweet Spot

Pay close attention to the plant tag! Some, like Veronica and Lithodora, crave full sun to produce the most flowers. Others, like Brunnera and Forget-Me-Nots, thrive in the cool of part-shade. Giving them the right light is half the battle won.

Watering Wisdom for Tiny Blooms

A common mistake is overwatering. It’s better to water deeply and less frequently than to give little sips every day. Check the soil with your finger; if the top inch is dry, it’s time to water. Plants in containers will need more frequent watering than those in the ground.

To Feed or Not to Feed?

Less is often more. A layer of compost applied in the spring is usually enough for in-ground plants. For heavy-blooming annuals in containers like Lobelia, a weekly feed with a balanced liquid fertilizer during the growing season will keep them performing their best.

How to Plant with Small Blue Flowers for Maximum Impact

Now for the fun part! Knowing how to plant with small blue flowers strategically can elevate your garden from nice to breathtaking. Here are a few of my favorite design tips.

Creating a “River” of Blue

Use low-growing, spreading plants like Blue Star Creeper or Grape Hyacinths to create a visual “river” of blue that meanders through a garden bed or along a path. Plant them in a dense, flowing pattern rather than in single clumps for a truly stunning effect.

Perfect Pairings: Companion Planting

Small blue flowers look incredible when paired with contrasting or complementary colors. Try these combinations:

  • With Yellow: The classic! Blue and yellow are opposites on the color wheel, creating a vibrant, energetic look. Think Grape Hyacinths with Daffodils.
  • With White: For a serene, elegant, and sophisticated feel. Imagine blue Lobelia spilling from a container filled with white Petunias.
  • With Silver Foliage: The cool tones amplify each other. Plant Veronica next to dusty miller or lamb’s ear for a beautiful, low-water combination.

Container Magic with Blue Hues

Don’t have a big garden? No problem! Many of these plants, especially Lobelia, Baby Blue Eyes, and Scabiosa, are perfect for pots. Use the “Thriller, Filler, Spiller” method: a taller plant in the center (the thriller), mounding plants around it (the filler), and your small blue flower (the spiller) trailing over the edge.

Common Problems with Plants with Small Blue Flowers (and How to Fix Them!)

Even the most experienced gardeners run into issues. Here are some common problems with plants with small blue flowers and how to get your plants back on track.

Leggy Growth and Fewer Flowers

This is almost always a sign of not enough sunlight. The plant is stretching to find more light. If possible, move it to a sunnier spot. For annuals like Lobelia, a mid-season “haircut” can also encourage bushier, more flower-filled growth.

Pesky Pests and Diseases

The best defense is a healthy plant! Proper watering and air circulation are key. Aphids can sometimes be an issue; a strong spray of water from the hose is often enough to dislodge them. For fungal issues like powdery mildew, ensure plants aren’t too crowded to allow for airflow.

Fading Flower Color

If your vibrant blues look a bit washed out, it could be due to heat stress or a nutrient deficiency. Ensure the plant is adequately watered during hot spells. For container plants, a dose of balanced fertilizer can often restore the richness of the color.

Sustainable and Eco-Friendly Choices for Your Blue Garden

Gardening is a wonderful way to connect with nature, and we can make choices that help our environment. Choosing sustainable plants with small blue flowers is easier than you think.

Prioritize native plants on our list, like Flax or certain species of Veronica, as they are adapted to your local climate and support native pollinators. Group plants with similar water needs together to conserve water. Finally, always opt for organic solutions like compost and mulch over chemical fertilizers to build healthy soil for the long term.

Frequently Asked Questions About Plants with Small Blue Flowers

Which small blue flower is easiest for beginners?

Grape Hyacinth (Muscari) is incredibly easy. You just plant the bulbs in the fall and they will come back year after year with virtually no effort. For an annual, Lobelia is also very forgiving and provides a huge amount of color for minimal work.
