Botanical Name: Ixora coccinea
Big, bright flower clusters give this beautiful tropical a couple common names: Flame-of-the-Woods and Jungle Geranium.
Now you can find cultivars available with blooms in shades of pinks, oranges and reds. Each star-like flower has 4 petals and can grow up to 1-in (2.5 cm) wide. Not that impressive, but put dozens of blooms together and those flower heads pack a lot of sizzling color on this compact shrub.
Glossy, oval leaves grow in opposite pairs on upright stems. Prune the plant back after flowering is over, if you want to keep it compact. Look for dwarf varieties -- ideal for growing in small containers.
This magnificent Ixora shrub prefers sunshine, warm temps and high humidity, like in its native tropical habitat.
No blooms? Ixoras that don't bloom aren't getting enough light. Put it in a warm greenhouse or sunroom to give your plant what it wants. Depending on where you live, moving Ixora to your patio for the summer may be ideal.
Repot in spring, moving up 1 pot size to give this beautiful flowering plant more room to grow. Use a pot with drainage holes to prevent soggy soil.
Overwinter Ixora indoors. This perennial evergreen doesn't like the cold at all. If you set your potted shrub outside for the summer, bring it in when the temperature drops below 60°F/16°C at night. This sudden change to low light levels will be a shock to the plant and it will likely drop a lot of leaves. Don't worry, it's normal. Reduce watering and stop fertilizing till spring.
Origin: India and Sri Lanka
Height: Dwarf varieties grow up to 2 ft (30 cm).
Light: Full sun to partial shade. Ixora coccinea needs plenty of direct sunlight to bloom. Scoot your plant outdoors for the summer, if you want, to give it the light it needs.
Water: Water thoroughly then allow the surface of the potting medium to dry out before watering again. Don't allow it to dry out too much -- Ixora will wilt and not bloom well if the potting mix is dry. Use rainwater, allowing it to warm up to room-temperature because cold water will shock this tropical native. Water less in winter.
Humidity: Moderate to high. If relative humidity drops below 50%, place pot on a tray of wet pebbles or use a room humidifier.
Temperature: Keep warm year-round (75°F/24°C) with a mininum temperature of 60°F/16°C. Protect plant from cold blasts from windows, entry ways and A/C vents.
Soil: Acidic peat moss-based mix, such as African violet potting mix.
Fertilizer: Feed every 2 weeks in spring and summer with an all-purpose water-soluble fertilizer diluted by half.
Propagation: Take 3-inch (8 cm) stem tip cuttings in spring or summer. Dip the cut end in water, then hormone rooting powder. Put the stem in moist potting mix, then firm the mix around the stem so that it stands up. Enclose the whole pot in plastic to maintain humidity. Roots should develop in about a month.
