Our Top Picks: 10 Stunning Reddish Purple Flowers

Ready for some inspiration? Here are some of my absolute favorite reddish purple flowers, suitable for a wide range of climates and garden styles. This list includes a mix of perennials, annuals, and shrubs to give you plenty of options.

1. Allium ‘Purple Sensation’

These are the showstoppers of late spring! Alliums produce large, globe-shaped flower heads on tall, slender stems. They look like whimsical purple lollipops popping up between other plants and are incredibly low-maintenance.

  • Type: Perennial Bulb
  • Sun Needs: Full Sun
  • Pro Tip: Plant them among lower-growing perennials. As the allium foliage starts to fade (which it does early), the other plants will grow up to hide it, leaving just the spectacular blooms on display.

2. Petunia ‘Black Velvet’ or ‘Supertunia Bordeaux’

For nonstop color all summer long, you can’t beat petunias. Modern varieties come in breathtakingly deep reddish-purple and near-black shades. They are perfect for hanging baskets, containers, and border fronts where they can spill over gracefully.

  • Type: Annual
  • Sun Needs: Full Sun
  • Pro Tip: Petunias are heavy feeders. To keep them blooming profusely, feed them with a water-soluble fertilizer every 2-3 weeks.

3. Clematis ‘Niobe’ or ‘Warszawska Nike’

If you want to add vertical interest, a clematis vine is the answer. These varieties produce huge, velvety, reddish-purple flowers that climb trellises, fences, or arbors with elegance. They are true garden royalty.

  • Type: Perennial Vine
  • Sun Needs: Full Sun for the vine, but shade for the roots.
  • Pro Tip: A classic piece of advice is to keep their “feet in the shade and heads in the sun.” Plant a small shrub or perennial at the base of the clematis to shade its roots from the hot sun.

4. Heuchera ‘Palace Purple’ (Coral Bells)

While primarily grown for its stunning foliage, Heuchera also sends up delicate wands of tiny flowers. The deep purple, maple-like leaves provide color and texture from spring through fall, making it a garden workhorse.

  • Type: Perennial
  • Sun Needs: Part Shade to Full Shade
  • Pro Tip: Heuchera is fantastic for brightening up shady corners where other flowers might struggle. It’s also largely deer-resistant!

5. Penstemon ‘Blackbird’ (Beardtongue)

This is a fantastic choice for a more natural, wildflower-style garden. ‘Blackbird’ produces tall spikes of deep wine-purple, bell-shaped flowers that are irresistible to hummingbirds. It’s also impressively drought-tolerant once established.

  • Type: Perennial
  • Sun Needs: Full Sun
  • Pro Tip: Good drainage is absolutely key for Penstemon. If you have heavy clay soil, amend it with compost and grit before planting.

  • Pro Tip: Don’t be afraid to give it a light trim mid-summer if it starts to look leggy. This will encourage bushier growth and even more flowers.

For a structural plant that delivers a punch, this shrub is unbeatable. It features dark, burgundy-purple foliage all season long, which provides a dramatic backdrop for its bright, rosy-pink flowers in late spring.

  • Pro Tip: For the best foliage color, make sure your Weigela gets at least six hours of direct sun per day. The color is less intense in shadier spots.

Just when your summer garden starts to fade, asters burst onto the scene. This variety offers masses of vibrant, reddish-purple daisy-like flowers that provide a crucial late-season nectar source for bees and butterflies.

  • Type: Perennial
  • Sun Needs: Full Sun
  • Pro Tip: To promote a sturdier, more compact plant and prevent flopping, pinch back the stems by about one-third in early summer (around mid-June).

9. Dianthus ‘Black Cherry Frost’

This charming perennial forms a low-growing mat of silvery-blue foliage, topped with fragrant, ruffled flowers in a rich crimson-purple hue, often edged in pink or white. It’s perfect for the front of a border or along a walkway.

  • Sun Needs: Full Sun
  • Pro Tip: Dianthus despises wet feet. Ensure it’s planted in well-draining soil to prevent root rot, especially during winter.
