WaterPersian Stonecress should be watered deeply yet infrequently to foster strong root growth; typically, watering once every week is sufficient. The amount needed will vary with the size of the plant and weather conditions, but as a general rule, aim for about one gallon per plant per watering session during active growth periods. During the dormant period in winter, reduce watering to every few weeks, depending on the soil dryness. Ensure the soil is well-draining to prevent waterlogging, which can cause root rot. It's crucial to adjust the frequency based on rainfall, and always check the soil moisture before watering.
LightPersian Stonecress thrives in full sunlight, where it can receive at least six hours of direct sun each day. The ideal spot for this plant is an area with unobstructed southern or western exposure that provides plenty of sunshine. Avoid placing it in deep shade, as this can hinder its growth and flowering potential.
TemperaturePersian Stonecress prefers a temperate climate with temperatures ranging from 40°F to 85°F for optimal growth. It can tolerate a brief dip below freezing, with a lower limit of about 30°F, and can survive up to approximately 95°F, but prolonged exposure outside this range can be detrimental. The ideal temperature for healthy growth and flowering lies between 60°F and 70°F.
PruningPrune Persian Stonecress to maintain shape, remove dead or spent flowers, and encourage a bushier growth habit. Deadheading after blooming can sometimes stimulate a second bloom period. Pruning is best done after the main flowering phase, typically in late spring or early summer. You may also trim the plant lightly to remove damaged or diseased stems anytime they appear.
CleaningAs needed
SoilThe Persian Candytuft requires well-drained, alkaline to neutral soil. A mix comprising equal parts of loam, sand, and peat with a splash of lime to raise the pH is ideal. Aim for a soil pH between 6.5 and 7.5 for optimal growth.
RepottingPersian Candytuft seldom needs repotting as it thrives in the same spot for several years. When grown in containers, repot every 2-3 years to refresh the soil.
Humidity & MistingPersian Candytuft tolerates dry to average humidity levels well. It does not require any specific humidity adjustments, making it adaptable to typical outdoor environments.

Life cycleAethionema capitatum, commonly known as Persian Stonecress, begins its life cycle as a seed, typically germinating in early spring when the temperatures are conducive to growth. Seedlings emerge and establish a small rosette of leaves during the vegetative growth stage. As the plant matures, it enters a reproductive phase, typically in late spring to early summer, where it produces tightly packed inflorescences of small, pink or white flowers at the tips of its stems. Following pollination, which is often mediated by insects, the flowers develop into seed pods that release seeds once they mature and dry. These seeds may lie dormant until the following spring to start a new generation. Throughout its life cycle, Aethionema capitatum may also spread vegetatively, forming clumps as it grows in its preferred rocky or sandy habitats.
PropogationPropogation time
Spring to Summer
Aethionema capitatum, commonly known as Persian Stonecress, is most successfully propagated through seed sowing. The ideal time to start seed propagation is after the danger of frost has passed in spring, ensuring a warm and stable environment for germination. Persian Stonecress seeds should be sown on the surface of a well-draining, sandy soil mix, as they need light to germinate effectively. Avoid covering the seeds with soil, instead gently press them into the medium and maintain a consistent moisture level without waterlogging the seeds. Providing a stable temperature around 70°F (21°C) will encourage optimal germination. Patience is needed because germination can be slow and uneven, taking several weeks to occur. Once seedlings have developed sufficiently and all risk of frost has passed, they can be transplanted into their permanent location outdoors, where they prefer a spot with full sun and good drainage.
