The Joy Of A Houseplant With Purple Flowers
There’s something magical about a houseplant with purple flowers. Purple blooms feel both regal and soothing, and indoors they glow against green foliage like little lanterns. I keep a rotating cast of purple-bloomers on my sunny kitchen shelves and they never fail to spark conversation — and new growth. If you’re hunting for the perfect purple, here’s your friendly, practical guide to plants that truly perform inside and how to keep those blooms coming.
Best Houseplants With Purple Flowers
African Violet (Saintpaulia)
If someone says “houseplant with purple flowers,” I picture a happy African violet. Compact, always in season, and available in every shade from deep grape to soft lavender, they’re the classic windowsill bloomer. Mine thrive under bright, indirect light and reward me with flowers most months of the year.
- Light: Bright, indirect (east or north window, or 10–12 inches under LED grow lights).
- Water: Keep evenly moist, never soggy. Bottom-water or wick-water to avoid wetting leaves.
- Soil: Fluffy African violet mix (peat or coco coir with perlite/vermiculite).
- Feeding: Violet fertilizer at 1/4 strength every 2–3 weeks while actively growing.
“I switched my violets to self-watering pots and a chunky violet mix — within a month, they doubled their bloom count.”
Cape Primrose (Streptocarpus)
Graceful, funnel-shaped flowers in vibrant purples make Streptocarpus a favorite on my plant rack. They bloom for months if you keep the light bright and the soil slightly on the dry side.
- Light: Bright, indirect, no harsh afternoon sun.
- Water: Let the top inch dry, then water thoroughly.
- Tip: Remove spent flower stems for continuous blooms.
Gloxinia (Sinningia speciosa)
Velvety leaves and large, bell-shaped purple flowers make gloxinia a showstopper. It behaves like a tuber: after flowering, it may rest. Don’t toss it — let it nap, then wake it up in spring.
- Light: Bright, indirect.
- Water: Keep lightly moist during bloom; reduce as it enters dormancy.
- Rest: Store the pot dry and cool for 8–12 weeks, then resume watering to re-sprout.
Phalaenopsis Orchid (Purple Moth Orchid)
When you want long-lasting purple blooms, go orchid. A healthy Phalaenopsis can hold flowers for three months or more, and the care is easier than most folks think.
- Light: Bright, filtered (sheer curtain is perfect).
- Water: About weekly; let bark mix dry slightly. No standing water in the crown.
- Feeding: Orchid fertilizer at 1/4 strength, “weakly, weekly.”
- Bloom trick: Drop nighttime temperatures 5–10°F in early fall to trigger spikes.
Trailing Streptocarpella (Streptocarpella saxorum)
A cousin to Cape primrose with a looser habit and dozens of small violet-blue flowers that flutter over the foliage for months. It loves bright light and a light hand with water.
- Light: Bright, indirect to soft morning sun.
- Water: Allow partial dry-down; avoid soggy soil.
Cyclamen
Winter brings out my purple cyclamen. Their butterfly-like flowers brighten gray days, and they prefer cool rooms where many tropicals sulk.
- Light: Bright, indirect.
- Temperature: Cool (ideally 50–65°F).
- Water: From the saucer; keep the crown dry.
Campanula (Bellflower)
Often sold in spring as a gift plant, Campanula produces cascades of purple bells. Treat it as a cool-season bloomer. It may rest or slow down in warm rooms.
- Light: Bright, indirect to soft morning sun.
- Water: Evenly moist, never waterlogged.
Achimenes (Hot Water Plant)
Think of Achimenes as a summertime indoor violet cousin with bright purple blossoms and a trailing habit that’s lovely in hanging pots.
- Light: Bright, indirect.
- Water: Keep evenly moist in growth; let dry when dormant.
- Note: Store the little scaly rhizomes dry over winter.
Bromeliads With Purple Flowers (Aechmea, Neoregelia, Billbergia)
Some bromeliads burst with purple tubular flowers amid colorful bracts. The flowers can be short-lived, but the display is dramatic, and pups ensure the show goes on.
- Light: Bright, indirect to dappled sun.
- Water: Keep a little water in the central cup; empty and refresh weekly.
- After bloom: Pups will grow around the base — separate when one-third the size of the parent.
How To Choose The Right Purple-Flowering Houseplant
Match Light To The Plant
- Bright, indirect light champions: African violets, Streptocarpus, Gloxinia, Phalaenopsis orchids.
- Cool bright windows: Cyclamen, Campanula.
- Supplemental light: In low-light rooms, a simple LED grow bar (12–14 hours daily) keeps purple blooms coming.
Think About Your Watering Style
- If you tend to overwater: Orchids in bark or bromeliads are forgiving when allowed to dry slightly.
- If you forget to water: Use self-watering pots for African violets and Streptocarpus to maintain steady moisture.
Consider Bloom Season And Longevity
- Long display: Phalaenopsis orchids (8–12+ weeks), African violets (repeat all year).
- Seasonal stars: Gloxinia, Cyclamen, Achimenes, Campanula.
Essential Care For Purple Blooms Indoors
Light That Promotes Flowers
Flowers form when plants get enough light — more than they need just to survive. Aim for bright, indirect light where your hand casts a soft shadow at midday, or run a grow light 12–14 hours daily. If leaves are stretching or blooms are sparse, it’s almost always a light issue.
Water And Humidity
- Moisture: Keep soil evenly moist for violets and gloxinia; allow partial dry-down for orchids and streptocarpus.
- Humidity: 40–60% is the sweet spot. Group plants, use pebble trays, or place a small humidifier nearby.
- Leaf care: For fuzzy-leafed plants (violets, gloxinia), avoid splashing the foliage to prevent spotting and rot.
Soil And Pots
- African violets and Streptocarpus: Light, airy mix — think fluffy, never heavy garden soil.
- Orchids: Bark mix or bark with sphagnum; clear orchid pots help monitor roots.
- Drainage: Always choose pots with drainage holes. Decorative cachepots are fine with a nursery pot inside.
Feeding For Flowers
- Violets and Gesneriads (Streptocarpus, Gloxinia): Balanced or blossom-formula fertilizer at 1/4 strength every 2–3 weeks.
- Orchids: 1/4 strength weekly, flush with plain water monthly to prevent salt buildup.
- Resting plants: Pause or reduce fertilizer during dormancy.
My Bloom-Boosting Routine
- Rotate pots a quarter turn each week for even growth.
- Deadhead spent blooms and remove yellowing leaves promptly.
- Refresh the top inch of mix every spring; fully repot violets every 12–18 months.
- Use a small fan on low to keep air moving — it dramatically reduces fungal issues in tight spaces.
“The day I embraced grow lights, everything changed. My violets and Streptocarpus went from shy to showy — now there’s always something purple in bloom.”
Easy Propagation For More Purple
- African violets: Leaf cuttings rooted in moist mix or perlite — new plantlets emerge at the base in a few weeks.
- Streptocarpus: Leaf strips laid flat on moist mix will sprout tiny rosettes along the cuts.
- Orchids: Encourage side shoots (keikis) on Phalaenopsis; pot up when roots are 2–3 inches long.
- Bromeliads: Divide pups when they’re one-third to half the parent’s size.
- Achimenes: Save and replant the small scaly rhizomes each spring.
Troubleshooting Purple Bloomers
- No flowers, just leaves: Increase light first. Then check if the plant needs a slight temperature drop (orchids) or a rest period (gloxinia, achimenes).
- Buds drop before opening: Avoid temperature swings and cold drafts; keep watering consistent.
- Leaf spots on violets: That’s water splash or strong sun. Bottom-water and add a sheer curtain.
- Crown rot: Common in violets when water sits in the center. Water from below and allow airflow.
- Pests: Mealybugs, thrips, and fungus gnats occasionally visit. Quarantine newcomers, wipe leaves with a mild soapy solution, and use sticky cards for gnats. For thrips on violets, I remove open blooms and rinse gently; repeat weekly until clear.
Design Ideas With Purple Blooms
- Windowsill harmony: Pair deep-purple African violets with pale-lavender varieties for a soft gradient.
- Height play: Tall orchid spikes behind low, mounded violets add dimension on a shelf.
- Color echo: Use plum or matte white pots to make purple flowers pop without competing.
Quick Picks By Situation
- Beginner-friendly: African violet, Phalaenopsis orchid.
- Cool room: Cyclamen, Campanula.
- Hanging display: Trailing Streptocarpella, Achimenes.
- Statement piece: Gloxinia in full bloom, purple Phalaenopsis with multiple spikes.
Frequently Asked Questions
What’s the easiest houseplant with purple flowers?
African violets are the most forgiving and reliable for repeat purple blooms. With consistent light and moisture, they flower almost year-round.
Can I grow lavender indoors for purple flowers?
You can, but lavender prefers intense direct sun and excellent airflow — most homes don’t offer enough. For true indoor conditions, choose African violets, Streptocarpus, or orchids instead.
How do I keep orchids blooming again?
Give bright, indirect light, feed lightly, and provide a small nighttime temperature drop in fall to initiate flower spikes. Don’t cut the spike until it browns; Phalaenopsis sometimes rebloom on a green spike.
Final Thoughts: Pick Your Purple And Enjoy
Whether you want a fuss-free violet that blooms on cue or a dramatic orchid that holds purple blossoms for months, there’s a houseplant ready to thrive in your space. Start with one plant that matches your light and watering style, add a simple grow light if your window is dim, and keep the care steady. Before long, you’ll have a little indoor gallery of purple flowers — and if you’re anything like me, you’ll wonder how you ever lived without them.
