The Telekia speciosa, most commonly known as the Heartleaf Oxeye or simply Oxeye, is a striking perennial plant recognized for its distinctive foliage and flowers. It bears large, heart-shaped leaves that are rough in texture with toothed edges, giving them a somewhat jagged appearance. These leaves often have a rich green hue that provides a lush backdrop for the bright yellow blooms. The flowers resemble those of sunflowers or daisies, featuring a prominent central disk surrounded by radiating petals. Each petal is narrow and elongated, contributing to the overall starburst effect of the inflorescence. The blooms are particularly eye-catching when they form dense clusters, creating a vivid splash of color that can enliven any garden setting. The plant generally exudes a rustic and robust charm, with its foliage and blossoms contributing to its ornamental appeal.

As needed
  • water dropWater

    The heartleaf oxeye should be watered when the top inch of soil feels dry to the touch, typically once a week. This plant prefers consistent moisture, so providing it with approximately 1 gallon of water per week is adequate. During hot or dry periods, the frequency may increase to two or three times per week, and during the cooler months, less frequent watering may be necessary. It’s crucial to avoid waterlogging the soil, so ensure good drainage and reduce watering if the soil doesn’t dry out between sessions.

  • sunLight

    Heartleaf oxeye thrives best in full sun to partial shade. It should be placed in a location where it can receive at least four to six hours of sunlight daily. Although it tolerates partial shade, too much shade can lead to leggy growth and fewer flowers, so a spot that offers a good balance of light and shade throughout the day is ideal.

  • thermometerTemperature

    Heartleaf oxeye is hardy and can withstand a broad range of temperatures, but it performs best when the temperature is between 60°F and 75°F. It can survive minimum temperatures down to 20°F and maximum temperatures up to 90°F. Providing mulch can help to regulate soil temperature and protect the plant during extreme temperature fluctuations.

  • scissorsPruning

    Heartleaf oxeye benefits from pruning to remove spent flower heads and encourage additional blooming. Pruning should take place after the first wave of flowering, typically in late summer or early fall. Cutting the plant back by one-third helps to maintain its shape and vigor. If necessary, light pruning can also be done in the spring to remove any winter-damaged foliage.

  • circleLife cycle

    Telekia speciosa, commonly known as the Heartleaf Oxeye or Yellow Oxeye, begins its life cycle as a seed, which when sown, will germinate under appropriate conditions of warmth and moisture. The seedling emerges with cotyledons (seed leaves) before it develops true leaves and establishes a root system. As a perennial, the plant enters a vegetative state where it grows foliage - large, heart-shaped leaves - and develops its rootstock more extensively. Over time, the Heartleaf Oxeye reaches maturity and in the summer months, it produces conspicuous yellow daisy-like flowers that attract various pollinators. After pollination, the flowers develop into achenes (fruits) containing seeds, which are dispersed by wind, water, or animals, ensuring the propagation of the species. The plant may die back to the ground in winter, with the roots remaining dormant until conditions favor new growth in the spring.

      Spring-Early Summer

    • The most popular method of propagation for Telekia speciosa, commonly known as the Oxeye, is through seed. Seeds can be sown directly in the ground in fall, allowing nature's cycle to stratify the seeds naturally over winter. Alternatively, for a controlled environment, seeds can be stratified by placing them in a cold place, between 32°F and 41°F (0°C to 5°C), for several weeks before sowing in spring. Once stratified, sow the seeds in well-drained soil, lightly covered, and keep them moist until germination, which usually occurs within two to three weeks. Seedlings can then be transplanted to their final location once they have developed true leaves and are big enough to handle.
