From our perspective, the single most coveted indoor location is the sun-facing window sill, particularly one that faces south (in the Northern Hemisphere) or north (in the Southern Hemisphere). This spot is our throne. Here, we receive the most intense and direct sunlight for the longest duration of the day, which is precisely what our photosynthetic processes crave. The sunlight through the glass provides the energy we need to produce strong stems, lush foliage, and, most importantly, our vibrant, daisy-like flowers. A minimum of 5-6 hours of direct sun here is non-negotiable for us to thrive and not merely survive. Without it, we become leggy, our stems straining and stretching pathetically towards any light source, and our flowering will cease entirely as we divert all energy to a desperate search for the sun.
If a sunroom or conservatory is available, this is our idea of a communal paradise. These spaces are typically constructed with ample glazing, often on multiple sides, which bathes us in sunlight from morning until evening. The extended hours of bright, natural light mimic our native South African conditions more closely than any other indoor location. The increased light intensity and duration in such a room support not just basic metabolic functions but encourage prolific and continuous blooming. Furthermore, the typically higher humidity levels in a plant-filled sunroom are a welcome bonus, helping to keep our foliage turgid and healthy.
We understand that your modern dwellings do not always have perfect, sun-drenched windows. In darker homes or during the deep winter months, a location under supplemental grow lights becomes a necessary and acceptable compromise. For us, not just any lamp will do. We require full-spectrum LED or fluorescent grow lights that replicate the sun's natural spectrum. The light source should be positioned close—only 6 to 12 inches above our foliage—and left on for 12-14 hours a day to convincingly trick us into believing it is a long summer's day. This artificial sun allows us to continue photosynthesizing effectively, preventing etiolation and supporting flower production even when the world outside is grey.
While light is our primary concern, the microclimate of your chosen indoor location is crucial. Even the sunniest spot can be undermined by a hostile environment. Firstly, we despise drafts. Placing us in the path of a frequently opened door or a leaky window subjects us to stressful temperature fluctuations that can cause bud drop and stunt our growth. Secondly, be mindful of excessive radiant heat. A west-facing window might provide great light, but if the afternoon sun heats the glass to extreme temperatures, it can literally cook our roots and scorch our leaves. Ensure there is good air circulation around us to dissipate heat but without creating a cold, blowing draft. Finally, remember to rotate our pots a quarter turn every week. This ensures all sides of our plant receive equal light, preventing us from developing a lopsided posture as we lean ungracefully towards the light source.
