Plants grown in shady areas tend to be leggy and have weepy growth, while those grown in full sun are denser with better branching.
Temperature Requirements
Aeollanthus rosulifolium P.A.Duvign. & Denaeyer grows well in warm to hot temperature conditions. The plant thrives in temperatures ranging from 20-30°C (68-86°F). At temperatures below 15°C (59°F), the plant growth slows down, and the leaves may turn yellow, wilt and eventually die.
Soil Requirements
The plant prefers well-drained soils rich in nutrients. Aeollanthus rosulifolium P.A.Duvign. & Denaeyer can grow in various soil types, including sandy, loamy, and clay soils. However, it requires frequent watering when grown in sandy soils as they can quickly dry out and deprive the plant of water and nutrients. A pH range of 6.0-7.5 is ideal for the plant's growth.
Cultivation Methods
Aeollanthus rosulifolium P.A.Duvign. & Denaeyer is a relatively hardy plant and can be grown both indoors and outdoors. However, it requires a warm climate to thrive, so if you're located in areas where the temperature drops below 60°F, then it's best to grow it in a greenhouse or indoors.
This species prefers well-draining soil that is rich in organic matter. You can mix peat moss, perlite, and vermiculite to create a warm potting mix that can hold moisture without becoming waterlogged. Ensure that the soil pH is around 6.0 -7.0, slightly acidic to neutral.
Aeollanthus rosulifolium P.A.Duvign. & Denaeyer prefers bright, direct sunlight, but it can also tolerate partial shade. If you're growing it indoors, place the pot near a south-facing window, or provide artificial light using grow lights. Outdoors, make sure the plant has access to at least six hours of sunlight per day.
Watering Needs
When it comes to watering the Aeollanthus rosulifolium P.A.Duvign. & Denaeyer, you need to be careful not to overwater the plant. This species prefers moderate watering and likes to be kept moist but not wet. Water the plant when the top inch of soil feels dry to the touch, and avoid leaving water to sit in the saucer underneath the pot.
During winter, reduce the watering frequency and only water when necessary to avoid overwatering the plant.
Fertilization
Aeollanthus rosulifolium P.A.Duvign. & Denaeyer responds well to regular fertilization. Feed the plant every two weeks using a balanced, water-soluble fertilizer during the growing season (spring and summer). You can also fertilize the plant with compost or organic fertilizers such as bone meal, fish emulsion, or blood meal.
Make sure to follow the instructions on the fertilizer package and avoid over-fertilizing the plant, as this can cause root damage and leaf burn.
Pruning
Pruning is essential to maintain the shape and health of Aeollanthus rosulifolium P.A.Duvign. & Denaeyer. Prune the plant regularly to remove yellow or damaged leaves, dead stems, and spent flowers. This will encourage the growth of new foliage and flowers.
If the plant is getting too big, you can also prune it back in late winter or early spring to control its size and shape. Be careful not to prune more than a third of the plant foliage as this can cause stress and slow down the plant's growth.
Propagation of Aeollanthus rosulifolium P.A.Duvign. & Denaeyer
Aeollanthus rosulifolium P.A.Duvign. & Denaeyer commonly known as 'Rosette-leaf Aeollanthus' is a herbaceous plant that belongs to the Lamiaceae family. Propagation of Aeollanthus rosulifolium can be done through different methods including:
1. Seed Propagation
One of the easiest ways to propagate Aeollanthus rosulifolium is through seed propagation. Collect seeds from the plant during the flowering season and soak them in water for 12-24 hours. Sow the seeds in well-prepared soil and keep them in a shaded area. Germination usually occurs within 2-4 weeks, but can take longer. Once the seedlings develop, transplant them to individual pots or in the garden.
2. Cuttings Propagation
Propagating Aeollanthus rosulifolium through cuttings is also possible. Take 5-6 inches long stem cuttings with at least two pairs of leaves and remove the lower pair of leaves. Dip the cuttings in a rooting hormone and plant them in a well-draining potting mix. Cover the pot with a plastic bag or place it in a propagator to retain humidity and place it in a bright, indirect light. Rooting usually takes 2-3 weeks after which you can transplant the cuttings in individual pots.
3. Division Propagation
Propagation through division is also a viable method. Divide the plant every 2-3 years during the spring season when the plant is actively growing. Carefully remove the plant from the pot and separate the clump into smaller sections using a sharp knife. Replant the newly divided plant in well-prepared soil.
