Ixora

Ixora coccinea

Ixora is a tropical evergreen shrub that builds a dense, rounded presence about 5 feet tall and 4 feet wide. Red-orange flower clusters carry the display from late spring into fall, making it useful where a long flowering season needs to hold a planting together. Its substantial evergreen outline suits permanent bed structure rather than a temporary gap-filler.

Placement and use

Use Ixora along a sunny foundation bed, at the back of a mixed border, or in a low flowering screen where its mature height will not cover windows or shorter plants. Set the planting far enough from paths that the foliage can occupy its full width without narrowing circulation. A grouped or linear planting reads as one continuous shrub mass, while a single plant works best where there is open bed space around it. Keep it out of locations exposed to frost.[1][2][3]

Spacing and mature footprint

Plant on 3-foot centers for a dense, joined planting. Because each shrub can spread about 4 feet wide, neighboring plants will grow together rather than remain as separate mounds; reserve the full run of bed length before planting. For an accessible hedge or border edge, leave a path-facing clearance beyond the planted row so mature foliage does not spill into the walking line.

Three plants set 3 ft apart, center to center; shaded circles show the 4 ft mature spread.

Sun, water, and soil

Place Ixora in full sun and give it regular water in moist, well-drained soil. Acidic soil is important to the planting plan: avoid alkaline pockets, especially beside concrete sidewalks and foundations, where foliage can lose its clear green color. If a foundation bed is the intended location, use a section with suitable soil rather than pressing plants tightly against the structure.[1][2][3]

Seasonal notes

The shrub remains evergreen in its frost-free range, so its 4-foot-wide footprint stays occupied through winter. Flowering begins in late spring and continues into fall, with the strongest display in a sunny position. Pruning can be fitted around the layout whenever needed to contain a shared hedge line, but shearing reduces the number of flowers.[2][3]

Planning caveats

Ixora is suited to USDA Zones 10 and 11 and needs a protected, frost-free site. Temperatures below 50°F can damage it, and light freezes may cut stems back to the ground even where plants recover in spring. Do not rely on its evergreen height for year-round screening where cold snaps are likely.[1][2]
