Care Guide

Water every 3 to 4 days during summer, allowing the soil to dry slightly between waterings. Reduce frequency to once a week in winter. Water at the base of the plant to keep foliage dry and prevent fungal issues.
Lighting
Requires full sun with at least 6 to 8 hours of direct sunlight per day. In partial shade, flowering is reduced and growth may become leggy and weak.
Ideal Soil
Prefers well-draining, light soil with pH between 5.8 and 6.5. Amend with coarse sand or perlite to improve drainage. Avoid heavy clay soils that retain excess moisture.
Recommended Pot
Terracotta or ceramic pots with good drainage holes for outdoor use. Avoid containers without drainage. For gardens, plant directly in raised beds or borders.

Common Problems
Alternaria Leaf Spot
Alternaria leaf spot is a common fungal disease caused by Alternaria solani and Alternaria alternata that affects a wide range of plants including tomatoes, potatoes, brassicas, and ornamentals. The disease thrives in warm, humid conditions and can cause significant crop damage if left untreated. Spores overwinter on plant debris and can attach to seeds, making complete elimination difficult.
Root Rot
Root rot is a serious fungal disease that affects the root system of plants, causing them to decay and die. It is primarily caused by overwatering, poor drainage, or soil-borne fungi such as Pythium, Phytophthora, Rhizoctonia, and Fusarium. The disease thrives in waterlogged conditions where roots are deprived of oxygen, making them susceptible to fungal infection.
Gray Mold (Botrytis Blight)
Gray mold, caused by the fungus Botrytis cinerea, is one of the most common fungal diseases in plants. It affects over 200 plant species, including ornamentals, vegetables, fruits, and houseplants. The disease thrives in cool, humid conditions with poor air circulation, causing grayish spots and soft rot on infected tissues.
Powdery Mildew
Powdery mildew is a common fungal disease caused by various fungi species including Erysiphe, Podosphaera, Oïdium, and Leveillula. It affects over 10,000 plant species worldwide. The disease thrives in warm, dry climates with high humidity and appears as a distinctive white powdery coating on plant surfaces.
Meaning & Symbolism
Symbolizes immortality, everlasting love, and unfading affection. The long-lasting blooms that do not wilt represent enduring sentiments and undying devotion.
