Our Top 7 Picks for Trees with Purple Flowers in California

Alright, let’s get to the fun part! I’ve cared for and admired countless trees over the years, and these seven are my absolute favorites for California gardens. We’ve got something for every style, from grand, dramatic displays to understated native beauties.

1. Jacaranda (Jacaranda mimosifolia)

You can’t talk about purple trees in SoCal without starting with the iconic Jacaranda. In late spring, these trees erupt in a breathtaking canopy of lavender-blue, trumpet-shaped flowers, carpeting the ground below in a magical purple blanket.

Best for: Creating a massive, show-stopping spring spectacle in larger yards.

  • USDA Zones: 9b-11
  • Sun/Water: Full sun and deep, infrequent watering once established. It’s surprisingly drought-tolerant!
  • Greeny Gardener Pro Tip: Be prepared for the flower drop! While beautiful, it can be messy on patios or driveways. Plant it in a spot where the fallen blossoms can be enjoyed as a natural mulch.

2. Crape Myrtle (Lagerstroemia indica)

If you want summer-long color, the Crape Myrtle is your friend. These hardy, fast-growing trees produce enormous panicles of flowers that last for months. Look for varieties like ‘Catawba’ or ‘Zuni’ for stunning shades of purple.

Best for: Reliable, long-lasting summer color and interesting winter bark.

  • USDA Zones: 7-10
  • Sun/Water: Loves the heat and full sun. Water regularly during its first year, then it becomes quite drought-resistant.
  • Greeny Gardener Pro Tip: Prune in the winter when the tree is dormant to encourage strong new growth and abundant flowers. Don’t worry—these trees are perfect for beginners!

3. Vitex (Vitex agnus-castus)

Also known as the Chaste Tree, Vitex is a champion of low-water gardens. It produces elegant, 12-inch spikes of fragrant lavender-blue flowers that bees go absolutely wild for. It can be grown as a large shrub or pruned into a lovely small, multi-trunked tree.

Best for: A water-wise, pollinator-friendly garden that needs a splash of cool color in the summer.

  • USDA Zones: 6-9
  • Sun/Water: Full sun is a must for the best blooms. It thrives on neglect and needs very little water once established.
  • Greeny Gardener Pro Tip: Deadhead the spent flower spikes to encourage a second, smaller flush of blooms in the late summer or early fall.

4. Princess Flower (Tibouchina urvilleana)

For a touch of the tropics, look no further. The Princess Flower boasts huge, velvety flowers in the most intense, electric shade of royal purple you’ve ever seen. While technically a large shrub, it’s easily trained into a spectacular small tree shape.

  • USDA Zones: 9-11
  • Sun/Water: Prefers morning sun and afternoon shade in hotter inland areas. Needs regular moisture to thrive.

5. Western Redbud (Cercis occidentalis)

Let’s talk about a true California native! The Western Redbud is a fantastic, sustainable trees with purple flowers in california choice. In early spring, before its heart-shaped leaves appear, its bare branches are covered in brilliant magenta-purple blossoms. It’s a true harbinger of spring.

6. Desert Willow (Chilopsis linearis)

Don’t let the name fool you—it’s not a true willow. This is another spectacular California native known for its hardiness. It produces fragrant, orchid-like, trumpet-shaped flowers in shades of white, pink, and a gorgeous lavender-purple. It blooms all summer long!

Here’s a unique choice that offers a different kind of purple. The Smoke Tree is primarily grown for its stunning, deep-purple foliage that lasts from spring to fall. In early summer, it produces large, airy flower clusters that look like puffs of purplish-pink smoke, hence the name!

Planting Your Purple-Flowered Tree: A Step-by-Step Guide for Success

You’ve picked your perfect tree—hooray! Now, let’s get it in the ground properly. Following these trees with purple flowers in california best practices will give your new tree the best possible start in life.

  1. Timing is Everything: The best time to plant most trees in California is in the fall. This gives the roots all winter to get established before the stress of summer heat arrives. Spring is the second-best option.
  2. Pick the Perfect Spot: Pay close attention to the sun requirements we listed above. Also, think about the tree’s mature size. Don’t plant a future giant Jacaranda right next to your house!
  3. Dig the Right Hole: Dig a hole that is two to three times as wide as the root ball, but no deeper. It’s crucial that the top of the root ball sits slightly above the surrounding soil level to promote drainage.
  4. Gently Free the Roots: Carefully remove the tree from its container. If the roots are tightly wound in a circle (root-bound), gently tease them apart with your fingers or make a few shallow vertical cuts with a knife. This encourages them to grow outward.
  5. Place and Backfill: Set the tree in the center of the hole. Fill the hole back in with the native soil you removed. There’s usually no need to add a lot of amendments directly into the planting hole, as this can discourage roots from expanding into the surrounding earth.
  6. Water Deeply: Build a small basin of soil around the tree to hold water. Water it slowly and deeply right after planting to settle the soil and eliminate air pockets. This is the most important watering it will ever get!
  7. Add Mulch: Apply a 2-3 inch layer of organic mulch (like wood chips or bark) around the base of the tree, but be sure to keep it a few inches away from the trunk itself. Mulch helps retain moisture, suppress weeds, and regulate soil temperature.

The Essential Care Guide for Thriving Purple Blooms

Now that your tree is planted, a little ongoing care will ensure it grows strong and produces those gorgeous flowers year after year. This is your go-to trees with purple flowers in california care guide.

Watering Wisely

The number one mistake California gardeners make is overwatering. For the first year, your tree will need consistent moisture to get established. After that, most of the drought-tolerant trees on our list prefer deep, infrequent watering. This encourages deep root growth, making them more resilient. Let the top few inches of soil dry out completely between waterings.

Fertilizing (or Not!)

Less is more! Most trees, especially natives like the Redbud and Desert Willow, do not need much fertilizer. A top-dressing of compost once a year in the spring is usually plenty. Over-fertilizing can lead to lots of leafy growth but fewer flowers.

Pruning for Shape and Health

Pruning can feel intimidating, but it doesn’t have to be. The main goals are to remove any dead, damaged, or crossing branches and to create a nice shape. The best time to prune is usually in the winter when the tree is dormant. For flowering trees like Crape Myrtles, pruning encourages the new growth that will produce summer blooms.

Troubleshooting: Common Problems with Trees with Purple Flowers in California

Even with the best care, you might run into an issue or two. Don’t panic! Here are some quick fixes for common problems.

  • Yellowing Leaves: This is most often a watering issue. Check the soil. If it’s soggy, you’re overwatering. If it’s bone-dry, you’re underwatering. Adjust accordingly.
  • My Tree Isn’t Blooming: Be patient! Many trees need a few years to mature before they start flowering. Other culprits can be not enough sunlight, improper pruning (cutting off the wood that will form flower buds), or too much nitrogen fertilizer.
  • Pests like Aphids: Often seen on new growth, especially on Crape Myrtles. A strong blast of water from the hose can often knock them off. For persistent problems, insecticidal soap is an effective, eco-friendly option.
