basil-leaved rockrose


Halimium ocymoides, commonly known as rock rose, is a flowering plant distinguished by its showy appearance. The plant is adorned with bright yellow flowers that are notably vibrant and eye-catching. These flowers have a saucer-like shape, radiating with a simplicity that is both charming and appealing. Each flower consists of five petals, which often feature a delicate pattern of reddish-brown spots at their base, creating an attractive contrast against the yellow background. The foliage of the rock rose presents a silvery-green hue, with leaves that are small, linear, and somewhat lance-shaped. These leaves can give the plant a slightly grayish tone, providing a beautiful backdrop for the brilliant yellow of the flowers. The leaves are arranged alternately along the stems, contributing to the overall bushy and dense appearance of the shrub. Rock rose blooms profusely during its flowering season, covering the plant in a blanket of yellow that is hard to miss in any garden setting where it is grown. Its showy display and complementary foliage make it a popular choice for ornamental purposes, adding a splash of color and Mediterranean charm to landscapes.

  • water dropWater

    The Rock Rose should be watered deeply, ensuring the soil is moistened thoroughly. It's essential to allow the soil to dry out between watering to prevent root rot. For young plants, watering might be necessary once or twice a week, but well-established plants are drought-tolerant and may require less frequent watering. During hot summer months, provide the Rock Rose with roughly 1 gallon of water every week if there has been no significant rainfall. In cooler temperatures or when established, water can be reduced to every two to three weeks.

  • sunLight

    The Rock Rose thrives best in full sunlight, which means it should receive at least six hours of direct sun daily. The ideal spot for this plant is in a south-facing garden, where it can soak up ample sunlight. Avoid too much shade, as this can impede the plant's bloom and overall health.

  • thermometerTemperature

    Rock Roses are resilient in a variety of temperature conditions and can withstand temperatures as low as 10 degrees Fahrenheit. However, they prefer warmer climates and optimum growth occurs between 60 and 75 degrees Fahrenheit. Protect them from extreme cold and frost, which might damage the plant.

  • scissorsPruning

    Pruning Rock Roses helps maintain their shape and encourages bushier growth with more flowers. Prune in late winter or early spring before new growth starts. Deadheading spent blooms throughout the growing season can also promote additional flowering. Typically, light annual pruning is enough, cutting back by a third.

  • circleLife cycle

    Halimium ocymoides, commonly known as Rockrose, starts its life cycle as a seed, which under proper conditions germinates in late winter to early spring. The seedling develops into a young plant with characteristic hairy, gray-green foliage. As the plant matures, it enters the vegetative stage, characterized by the growth of stems and leaves, preparing for the reproductive phase. Flowering occurs in late spring to summer, showcasing yellow flowers with a dark maroon spot at the base of each petal, which are pollinated by insects. After pollination, the plant produces dry, capsule-like fruits, containing seeds that are dispersed by wind or animals. Rockrose is a perennial, surviving for several years and going through the flowering and seed-setting stages annually.

  • sproutPropogation

    • Propogation time


    • Propogation: The most popular method for propagating Halimium ocymoides, also known as rockrose, is by semi-hardwood cuttings. This technique is commonly performed in late summer when new growth has partially matured and stems are neither too soft nor too woody. To propagate, select healthy, disease-free growth and make a cutting about 4 to 6 inches long. Strip off the lower leaves, dip the cut end in rooting hormone to enhance root development, and plant the cutting in a well-draining potting mix. The pot should then be placed in a warm area with bright, indirect light and kept moist until roots develop, generally within a few weeks. Ensuring a high humidity environment can be beneficial, which can be maintained by covering the pot with a plastic bag or a humidity dome.
