The Ohio Spiderwort (Tradescantia ohiensis) is a vigorous herbaceous perennial that is favored for its clusters of three-petaled, mostly blue (sometimes rose) colored blooms with bright yellow stamens. Each flower only lasts around one day, but it blooms profusely for six weeks and is never out of blooms. This flower is relatively adaptable and looks terrific in beds, borders, or cottage gardens.
The name “Spiderwort” is derived from the Greek word “tradescantia”, meaning “spider-like”, and the Latin species name, “ohiensis”, which means, “of the Ohio”. This flower has ties to both English and Native American cultures. In the English language, spiderwort directly refers the plant’s similarities to spiders, which is indicative of its eating abilities. In Native American cultures, the plant has many uses, from medicinal purposes to use in dyes. The Ohio Spiderwort is a member of the family Commelinacea and is a perennial.
How to Plant
The Ohio Spiderwort can be planted almost anywhere and is quite hardy in outdoor gardens. For optimal growth, they should be planted in a slightly acidic soil with a pH of 6-7. When planting, ensure that there is at least one foot of spacing between each plant. The soil should be enriched with some compost and it should be well-drained. This flower should receive at least 6 hours of direct sunlight per day, however, it does prefer full sunlight.
Watering the Ohio Spiderwort regularly is important for healthy growth. The flower should be watered whenever the soil begins to dry out, however this can vary based on where the plants are located. For example, outdoor plants that are in direct sunlight may need to be watered more often than those that are in the shade. Be careful not to overwater the flower, as this can lead to root rot.
A layer of mulch around the flower will help to keep the soil moist and cool. Spiderwort can tolerate temperatures as low as -10 degrees Fahrenheit and is considered to be winter-hardy in USDA zones 5-9.
Meaning and Symbolism
The Ohio Spiderwort reflects a pious reverence since ancient times. The flower is said to symbolize both passion and suffering, depending on its color. Blue flowers are associated with overcoming challenges and finding solace in the face of tragedy, whilst rose-colored blooms signify passionate love, beauty, and the arrival of a new dawn.
History, Mythology, and Religious Significance
Spiderwort has long been significant in both English and Native American culture. In English folklore, the plant was used to ward off evil spirits, as spiders were seen as harbingers of both ill fortune and good news. It was also believed that a gift of Spiderwort could bring good luck.
Amongst Native Americans, the plant held a great amount of importance. The Cherokee used spiderwort to make a blood medicine, the Cree used spiderwort for treating colds, and the Cherokee also used spiderwort for salad and chowder. In addition, the flowers were used to create dyes for clothes and baskets.
Flower Varieties and Their Defining Characteristics
Tradescantia ohiensis is known as the Ohio Spiderwort. Other varieties of spiderworts include Tradescantia pallida (synonym Setcreasea pallida), which is known as Purple Heart, Wandering Jew, and Purple Queen. The genus of Tradescantia comprises around 75 species, which are found in tropical and subtropical areas of the Americas.

How to Pot and Repot
Potting and repotting Ohio Spiderwort is an easy process. Begin by choosing a pot that has a drainage hole and is slightly larger than the plant’s root systems. Fill the pot with potting soil and make sure to tamp it down slightly to ensure that it is packed in tightly. Place the plant in the pot and fill in the remainder with soil, ensuring it is firmly packed around the roots.
Water the soil lightly and allow it to drain properly. Once the water has drained out of the bottom of the pot, move the pot to a sunny spot. Remember, it is important to make sure that the plant is not exposed to frost or extreme temperatures. Always use a potting soil mix when potting or repotting and be sure to use a light fertilizing solution in the warmer months.
How to Prune
Ohio Spiderwort should be pruned regularly to maintain a neat and tidy appearance. Begin by cutting off any dead or dying flowers and leaves. If the plant has become too dense, it can be pruned back to control its size and shape. Pruning should be done in late winter or early spring before new growth begins. It is important to use clean, sterilized pruning implements and to remove any remaining plant material to avoid the spread of any diseases.
How to Propagate
Propagation of Ohio Spiderwort is simple but must be done at the appropriate time of year. The best time for propagating the flower is in spring and fall when the weather is cooler. You can propagate spiderwort by division or by seed. When dividing the plants, be sure to have at least three or four stems per division. Plant each division in a separate pot.
If you’d like to propagate spiderwort from seed, you can start the seeds indoors in late winter or autumn. Sow the seeds directly on the potting media and lightly cover with soil. Place the pots in an area that receives bright, indirect light and keep the soil moist. The seeds should germinate in 10-14 days.
Common Pests and Diseases
Spiderwort is fairly resistant to pests and diseases, however, they can be susceptible to root rot, rust, mildew, and aphids. The best way to prevent these issues is by providing the plants with adequate drainage and ensuring that they are not overwatered. If the plants are affected by any pests or diseases, you can use an insecticidal soap or fungicide to control them.
