5 Indoor Flowering Plants To Brighten Up Your Winter

Turn your Japan home into a winter haven with indoor blooms! We’ve come up with a list of five flowering plants to adorn your Japan interiors and some tips to help them be their best selves.

While Japan has many lovely winter flowers to enjoy outdoors, the inside of our apartments can feel drab and chilly from December to March. As the weather cools, we retreat indoors and spend more time huddled under blankets, thick sweaters and fuzzy socks. This is where indoor flowering plants come in—adding warmth, color and life to your living space during the colder months. The indoor world feels far more inviting when flowers help offset the gray winter skies.

1. African Violets

Despite having a (somewhat unwarranted in my opinion!) difficult reputation, afurika sumire (African violets) are beloved flowering houseplants that will bloom all year round. They come in several varieties and feature a petite size, vibrant colors—most commonly purple, red, pink or white—along with rosette-like flowers and soft, fuzzy leaves. You can easily group a number of these flowers together to create a colorful arrangement that will brighten your home this winter.

These plants thrive in bright, indirect sunlight, preferably near a window, and in well-ventilated environments free from cold drafts. African violets also require a well-draining potting mix, as they perform poorly in either too dry or waterlogged soils. Although these plants prefer humid environments, they are sensitive to misting or having their leaves wet. This can cause browning spots to form. For constant blooms, be sure to fertilize regularly and deadhead the flowers as soon as they are spent.

2. Indoor Roses

You may be surprised to learn that bara (roses) can be grown indoors. However, given the right conditions, these uncommon house plants, too, can sit alongside your other flora. Miniature roses (ミニチュアローズ) are the best and will flower just as beautifully in your home as they would outside, provided you offer them the right environment. Miniature infinity roses (インフィニティローズ), for example, are a type of mini rose that are easy to find in Japan (even in supermarkets sometimes!) and bred for life inside.

Roses require ample sunlight—at least six hours of direct light near a southern or western exposed window—otherwise, they will not be able to thrive. Additionally, like other indoor flowering houseplants, they require a warm and humid environment. Roses are prone to spider mites and are more susceptible if the air becomes too dry. As such, placing them on a bed of moist pebbles is one option to maintain their ideal humidity levels. These plants, like all of our flowering friends, will also likely need regular fertilizing to bloom indoors.

3. Begonias

Begonias (ベゴニア) are versatile plants with striking leaves and colorful, rose-like flowers. Several varieties exist, but wax begonias—named for their waxy leaves—remain the most popular thanks to their unfussy nature and bright foliage. Begonias make lovely, affordable gifts and add a touch of attractiveness to any houseplant collection.

Begonias are relatively easy to care for, but overwatering can cause root rot. Allow the soil to dry out completely and let the plant show slight drooping before watering again. Additionally, since they are tropical plants, they require warm and humid environments (which is usually not a problem for most of the year in Japan). Begonias enjoy indirect sunlight and generally grow well indoors because they don’t need extensive hours of daylight to produce a continuous supply of gorgeous blooms.

4. Anthuriums

Anthuriums (アンスリウム) originate in the warm, humid rainforests of South America and stand out for their dramatic flair and low-maintenance nature. Their flowers, or “spathes,” resemble large, brightly colored leaves that bloom in bold reds, pinks and whites. Because they resemble poinsettias, anthuriums have grown increasingly popular as winter holiday decorations. These flowers make festive centerpieces and pair beautifully with other tropical plants, such as orchids and begonias, for year-round displays.

Anthuriums typically flower sporadically throughout the year, with each flowering period lasting about eight weeks. They may take a few months to adjust to a new environment, so don’t worry if blooms don’t appear right away. Place them near a window for direct sunlight, especially in winter, and maintain high humidity to help them thrive.

5. Orchids

Although ran (orchids) are known for being difficult indoor plants, they’re nevertheless a popular choice for their unique beauty and array of colorful blooms. The most common one is the gochooran (Phalaenopsis orchid), also known as a moth orchid for its eponymously shaped flowers. Measuring about two to five centimeters in diameter, these flowers can come in whites, purples and yellows and are capable of flowering for four to six months of the year.

When keeping orchids, one fatal mistake is overwatering. While they certainly like quite a bit of water, root rot tends to settle in easily. As such, water orchids only when the top of the soil feels slightly dry. Choose soil explicitly designed for orchids, or opt for a well-draining mix that doesn’t dry out too quickly. Place them near east- or west-facing windows for direct sunlight, maintain 40–60% relative humidity, and allow a 10-degree difference between daytime and nighttime temperatures to enjoy showy blooms at least once a year—and twice if you’re lucky.

With these five flowering flora, you’re well on your way to making your Japanese home warmer with splashes of colorful petals.
