Due to its rapid and adaptable growth, it’s essential to watch for invasiveness, especially in coastal regions. Bees, butterflies, hummingbirds, and a wide range of insects and songbirds are drawn to its nectar-rich flowers. Trimming the flower panicles before they seed helps to cut down on dispersion.
Light
Pride of Meidra thrives in four to six hours of full sun each day. Partial sun is also acceptable, and the afternoon sun is preferable to the morning sun, as light intensity is more significant at that time.
Soil
Pride of Madeira accepts versatile soil conditions, including clay, sand, and loam, and can tolerate a wide range of pH levels. In any soil, however, good drainage is essential. This shrub is also particularly salt-tolerant, given its island origins, making it an ideal plant in coastal climates.
Water
Pride of Madeira is fairly drought-tolerant, but watering regularly during the flowering season will ensure its blooms stay healthy and vibrant. But, if you notice its flower heads drooping in hot weather, or its foliage appearing yellow, water at the base of the shrub to revive it.
Temperature and Humidity
The pride of Madeira won’t survive temperatures consistently below 50 F. As a coastal plant, the pride of Madeira grows best in the humid ocean air but doesn’t require any special humidity conditions in gardens unless planted in a desert climate. This shrub may need occasional misting in desert air to keep its leaves and flowers bright.
Fertilizer
Pride of Madeira doesn’t require fertilizer, as it can survive in low-nutrient soil. If you want to fertilize the shrub lightly, you may use compost in the fall and mineral fertilizer in the spring.
Pruning
You should cut spent flower stalks regularly to maintain a neat appearance and encourage new growth. Light pruning in summer and late fall will also help preserve the fullness of the pride of Madeira’s foliage.
Propagating Pride of Madeira
There are several benefits to propagating your pride of Madeira through cuttings. Primarily, your new shrub will be genetically identical to its parent shrub, creating uniformity in your garden. You should propagate pride of Madeira in mid-summer. Here’s how to propagate:
How to Grow Pride of Madeira From Seeds
Pride of Madeira can be easily propagated from seeds and does not require cold stratification because it is suited to warm growing zones. Plant in potting soil with compost around 1/8-inch deep, and put a thin layer of sand over the top to anchor seeds. Mist lightly each day, maintain a consistent temperature of 60 F to 70 F throughout germination (up to two weeks), and use a heating coil beneath planting trays if necessary.
Overwintering
You should protect your shrub in the winter by covering it with a frost blanket. It can temporarily survive in temperatures as low as 41 F, but no lower. You may overwinter your pride of Madeira in a bright spot indoors or a frost-free greenhouse.
Common Pests and Plant Diseases
Pride of Madeira is generally pest-free but can occasionally attract whiteflies, spider mites, and slugs. They are mainly disease-free, but insect infestations can attract viruses and bacteria. You can remove slugs manually, and you can eradicate spider mites by using insecticidal soap.
How to Get Pride of Madeira to Bloom
Pride of Madeira blooms in the spring and summer and presents spiky, purple, conical clusters of 20 inch flowers with red stamens. These flowers don’t bear a fragrance but have sweet nectar that attracts hummingbirds and butterflies. You can encourage bloom with proper watering practice and ensuring adequate sunlight. You should deadhead flowers and leaves throughout bloom, but only prune after blooming is complete. Pride of Madeira is biennial, so it only flowers every other year. However, in inland climates, they can sometimes present as perennials.
Common Problems With Pride of Madeira
The pride of Madeira is a very easygoing shrub but, like all plants, can present a few problems if not cared for attentively. Still, you likely won’t have to deal with many issues.
Dusty Appearance
If your pride of Madeira is planted in overly humid conditions, it may develop powdery mildew on its leaves and flowers, making the plant look dusty or dark. You should treat this by removing the affected foliage and treating it with an anti-fungal spray.
Yellowing Leaves
The pride of Madeira can develop yellowed leaves if it is over-fertilized or over-watered. Pride of Madeira grows well in poor soil, so if your soil is too rich, it may cause problems with leaves. Revaluate your soil or fertilizing practices if you notice yellowing leaves.
Sprawl
While the sprawling pride of Madeira may be ideal for your large garden, it can be challenging to control if you’re planting in limited space. Excessive pruning isn’t necessary, but you may prune very lightly to limit unwanted growth.
