Royal is very showy for sales in large pots; used throughout Asia in ceremonial bouquets and garlands. Large, fully double flowers – 4 to 4.5 in./10 to 11 cm across – bloom in 4-in./10-cm pots in 70 days under short-day conditions. Bushy, 20-in./50-cm plants have sturdy stems that hold up in all weather. Requires little outdoor maintenance, as plants “outgrow” and hide old flowers.
