You’re walking through a botanical garden or maybe just scrolling through a frantic gardening group on Facebook when you see it: a purple white and yellow flower that looks almost too perfect to be real. It’s tri-colored. It’s vibrant. It’s exactly what your garden is missing. But here is the problem. "Tri-color flower" is a broad search term, and honestly, if you just type that into a search engine, you’re going to get a million results for pansies and nothing else.
Nature loves this specific color palette. It’s high-contrast. It’s loud. It’s designed to scream at bees, "Hey, the nectar is right here!"
Whether you’re looking at a delicate wildflower or a structured perennial, these three colors often show up together because they sit in a specific relationship on the color wheel. Purple and yellow are complementary. White acts as the "negative space" that makes both of them pop. It’s a classic look. But let’s get specific, because "purple white and yellow" could mean anything from a $15 orchid to a weed growing in your driveway.
The Usual Suspects: Pansies and Violas
If you saw this flower in a window box or a hanging basket, it was almost certainly a Viola tricolor. Most people just call them Johnny Jump Ups. These things are tough as nails. They’re technically short-lived perennials, but most gardeners treat them as annuals. You plant them when the air still feels like ice in March, and they just... thrive.
The Johnny Jump Up is the quintessential purple white and yellow flower. Usually, the top petals are a deep, velvety royal purple. The middle petals fade into a creamy white, and the very center—the "throat"—is a bright, sunshine yellow. Sometimes they have "whiskers," which are just dark lines that guide insects toward the pollen.
Interestingly, these flowers are edible. You’ve probably seen them crystallized in sugar on top of an expensive wedding cake or tossed into a fancy salad at a bistro that charges $20 for greens. They taste like grass. Maybe a little bit of wintergreen if you're lucky. But they look incredible.
There is a bigger version, too. The garden pansy (Viola x wittrockiana). These are the ones with the "faces." They come in huge varieties, but the purple, white, and yellow combination is a staple for a reason. If you want high-impact color that lasts through a frost, this is your winner. Just don't expect them to survive a 90-degree July day. They’ll melt. Literally. They turn into mushy stalks the moment the humidity hits a certain point.
Iris: The Architect of the Garden
Maybe the flower you saw wasn't a tiny little thing on the ground. Maybe it was tall. Stately. A bit dramatic.
If it had floppy petals and looked a bit like a medieval heraldry symbol, you’re looking at an Iris. Specifically, many Dutch Irises and some Bearded Iris varieties sport this exact tri-color scheme. Look at the variety 'Apollo' or 'Eye of the Tiger.'
Irises have a unique anatomy. You have the "standards" (the petals that stand up) and the "falls" (the ones that droop down). In many cultivars, the standards might be a pale violet or white, while the falls are a deep purple with a shocking yellow "beard" or signal patch right in the middle.

Why the Yellow Spot Matters
That yellow bit isn't just for decoration. It's a landing strip. Bees see in the ultraviolet spectrum. To a bee, that yellow patch on a purple and white Iris glows like a neon "Open" sign at a 24-hour diner. It tells the bee exactly where to stick its head to get the goods.
If you want to grow these, you need to know about rhizomes. They aren't bulbs. They're thick, ginger-looking roots that need to "bask" in the sun. If you bury an Iris rhizome too deep, it won't bloom. It’ll just grow leaves and mock you. Leave the top of the root exposed to the air. It feels wrong, like you're leaving the plant's toes out of the covers, but it’s the only way they stay healthy.
The Wild Side: Bird's Foot Violet and Bittersweet Nightshade
Sometimes the purple white and yellow flower you're hunting for isn't in a garden at all. It’s in the woods.
The Bird's Foot Violet (Viola pedata) is a North American native that is significantly more refined than its garden-center cousins. The leaves actually look like a bird’s foot—thin and splayed out. The flowers are bicolor or tricolor, often featuring those deep lavender tones with a bright orange-yellow center and white highlights. These are notoriously finicky. They hate "good" soil. If you try to give them fertilizer and rich compost, they’ll die out of spite. They want sandy, acidic, miserable-looking dirt.
Then there’s the Bittersweet Nightshade (Solanum dulcamara).
Be careful with this one. It’s a vine. You’ll see it tangled in fences or trailing over old logs. The flowers are small but stunning: five purple petals that peel back to reveal a bright yellow cone of stamens, often with a white ring at the base. It looks exotic, almost like a tiny shooting star.
Do not eat it. It’s not "instantly drop dead" toxic like its cousin Belladonna, but it’ll give you a very bad weekend. It’s an invasive species in many parts of the U.S., but gardeners often leave it alone because the flowers are so striking. It eventually turns into bright red berries that look like tiny tomatoes. Again, don't eat them.
Tropical Vibes: The Angelonia and Nemesia
If you're looking at a summer garden and see spikes of flowers, you might be looking at Angelonia, often called Summer Snapdragon. There are specific cultivars, like those in the 'Serena' or 'Archangel' series, that mix these colors.
However, the real "triple threat" is the Nemesia.

Nemesia is a cool-weather plant that comes from South Africa. Varieties like 'Sunsatia' or 'Aromance' have been bred to feature incredible bicolors and tricolors. You’ll find some that are a bruised purple on top, white in the middle, and have a yellow "pouch" at the bottom.
The best part? They smell like vanilla or coconut.
Honestly, most people overlook Nemesia because they look a bit delicate. They aren't. As long as you don't let them bone-dry in a pot, they’ll bloom their heads off. They’re perfect for that "cottage core" aesthetic that everyone is obsessed with right now.
The Crocus: The First Sign of Life
We can't talk about a purple white and yellow flower without mentioning the Crocus.
When the snow is still melting and everything looks gray and depressing, the Crocus Sieberi 'Tricolor' shows up. It is a literal miracle in the mud. The bottom of the flower is yellow, the middle is white, and the top is a lilac purple.
They are tiny. Maybe three inches tall. But when you plant 50 of them in a lawn, it looks like a painting.
- Planting tip: You have to plant these in the fall. If you're looking for them in the spring, you're too late. Buy the corms in October, shove them in the ground about 3 inches deep, and forget about them.
- Squirrel warning: Squirrels think crocus corms are delicious truffles. If you have a squirrel problem, drop a handful of crushed gravel or some red pepper flakes in the hole when you plant them. It won't hurt the flower, but it’ll give the squirrel a nasty surprise.
Identifying Your Mystery Flower
Still haven't found the one? Let's look at the structure.
If the flower is bell-shaped and hanging down, it might be a Fritillaria. Some species have a checkered purple and white pattern with a yellow interior. They look like something out of an Alice in Wonderland set. They also smell faintly of wet dog, which is a great way to keep deer away but a terrible way to start a bouquet.
If the flower is daisy-like, you're probably looking at an Osteospermum (African Daisy). Breeders have gone wild with these. You can find "3D" varieties where the outer petals are purple, the inner tuft is white, and the very center disk is a bright, metallic yellow. They close up at night, which is kind of moody and cool.

A Quick Breakdown of Leaf Shapes
Sometimes the flower isn't enough to go on. Look at the leaves:
- Heart-shaped leaves: Probably a Viola or Pansy.
- Sword-like, stiff leaves: Definitely an Iris.
- Fern-like, feathery leaves: Could be a Nemesia or a wilder species of Linaria.
- Glossy, dark green oval leaves: Likely a tropical like Angelonia or even a specific type of Orchid (like a Dendrobium).
How to Design a Garden Around These Colors
Most people make the mistake of buying one of everything. Don't do that. It looks messy.
If you love the purple white and yellow flower look, pick a "primary" and a "secondary." Use the purple as your anchor—maybe a deep purple Salvia or Lavender. Use white as your filler (Alyssum is great for this). Then, use the yellow as your "spark." A few yellow Marigolds or a Coreopsis will make the purple look twice as deep as it actually is.
This color combo is essentially the "Lakers" palette or a royal crest. It’s bold. It works best in full sun. In the shade, the purple tends to disappear and look like a dark hole, while the white and yellow will glow. If your garden is shady, lean heavier on the white and yellow and use a pale lavender instead of a deep royal purple.
Practical Steps for Success
If you've identified your flower and you're ready to get your hands dirty, keep these three things in mind. First, check your zone. A Crocus will never grow in Miami, and a tropical Angelonia will turn to black slime in a Vermont October.
Second, drainage is non-negotiable. Almost all of the plants mentioned—especially Irises and Violas—hate "wet feet." If your soil feels like heavy clay, add some compost or perlite.
Third, deadheading. This sounds violent, but it just means pinching off the dead flowers. For pansies and violas, this is the secret to keeping them blooming for months. If you let them go to seed, the plant thinks its job is done and it’ll stop producing those beautiful purple, white, and yellow blooms.
Go to your local nursery and look for "Tricolor" on the tag. Usually, growers make it easy for you. Grab a bag of high-quality potting soil, a terra cotta pot, and start small. You don't need a massive estate to enjoy these. A single pot of Johnny Jump Ups on a balcony can be just as satisfying as a whole meadow of wild violets.
