  • water dropWater

    Nemesia should be watered deeply but infrequently, allowing the soil to dry out slightly between waterings. The right amount would typically be 1 to 1.5 inches of water per week, depending on weather conditions and soil drainage. It's important to avoid overhead watering to reduce the risk of foliar diseases; instead, water at the base of the plant. During the hotter parts of summer, you may need to water more frequently, especially if the Nemesia is in containers. Ensure that pots have good drainage to prevent waterlogging, which can lead to root rot.

  • sunLight

    Nemesia prefers full sun to partial shade conditions for optimal growth. A location that receives at least 6 hours of direct sunlight is ideal, but they can tolerate some light afternoon shade, especially in hotter climates. Place your Nemesia where it can bask in the morning sun, which is less intense, and be protected during the peak heat of the day.

  • thermometerTemperature

    Nemesia thrives in cooler temperatures and can usually withstand light frosts. They perform best when daytime temperatures are between 60 and 75 degrees Fahrenheit, although they can survive in temperatures as low as 30 degrees Fahrenheit for short periods. The upper temperature limit for Nemesia is around 80 degrees Fahrenheit, beyond which they might start to suffer.

  • scissorsPruning

    Pruning Nemesia involves deadheading spent flowers to encourage more blooms and maintain the plant's appearance. Remove the dead flowers and any weakened or damaged stems regularly throughout the blooming season. The best time to prune for shaping is in the early spring, just as new growth begins to appear.

  • circleLife cycle

    The Nemesia Aroma Rhubarb and Custard, often known simply as Nemesia, starts its life as a seed which, with adequate moisture and temperature, germinates and emerges as a seedling. The seedling grows into a vegetative plant, producing a rosette of leaves and establishing a root system. As it matures, the Nemesia enters the flowering stage, developing distinctive red and yellow blooms that attract pollinators and give the plant its common name. After pollination, the flowers produce fruits that contain seeds, completing the reproductive cycle. If conditions allow, these seeds will disperse and eventually germinate, giving rise to new plants. Over time, the plant will senesce, beginning to deteriorate until it ultimately dies, although it may complete several flowering cycles within its lifespan, which is generally a single season as it is often grown as an annual.

      Spring to Summer

    • The Nemesia Aroma Rhubarb and Custard, a delightful plant with a scent reminiscent of its namesake dessert, is typically propagated through seeds. The most popular method involves sowing seeds in the early spring. To do this, begin by scattering the seeds on top of a moist, well-draining seed starting mix in a tray or pots. Barely cover the seeds with the mix because they need light to germinate. Place the tray in a warm spot, around 65 to 70 degrees Fahrenheit (18 to 21 degrees Celsius), and keep the soil consistently moist but not waterlogged. Seedlings usually emerge within 10 to 21 days. Once they have grown large enough to handle and after the threat of frost has passed, they can be transplanted outdoors to a sunny location with well-draining soil.
