For special effects or themes like gothic gardening, coloured bulbs in red or blue are available. Yellow and green light work for foliage while red lighting is often used on terra cotta features as well as autumn coloured foliage plants. A point to bear in mind is that artificial lighting may affect certain flowering plants whose flowering is dependant on a certain day length. Last but not least, fire has a warmth and glow that cannot be duplicated successfully by artificial means and for this reason garden torches and candles remain popular even though safety may be a concern. Garden candles are useful in that apart from the atmosphere they impart, they can also repel mosquitoes and be aroma therapeutic.
Fire is essential to the African garden theme.
