Evergreen

Landmark rhododendron

Rhododendron 'Landmark'

Rhododendron 'Landmark' is a rounded evergreen shrub with deep pink flower clusters that can read as red from a distance. Its bloom comes early to midseason, while the foliage gives the planting year-round structure. Plan for about 4–5 feet of height and 3–4 feet of spread, allowing room beyond the current pot size; larger specimens are possible over time. In Southwest Washington, place it in partial shade with acidic, well-drained soil. A spot protected from prolonged saturation and summer drying suits its shallow roots. It can anchor a shaded border or sit among other acid-loving shrubs where its spring flowers remain easy to see.

The right plant, the right place

Make room for something good.

Its rounded evergreen form can give a partially shaded border structure through the year. Deep pink flower clusters provide the seasonal display.

Where to plant

Allow about 3–4 feet for its expected spread, with room for further growth. Partial shade is a suitable exposure and may reduce severe lace bug infestations.

Through the seasons

Deep pink blooms appear early to midseason and may look red from a distance. The rounded foliage remains evergreen.

Southwest Washington gardens

Give it a good start.

In Southwest Washington, watch for rhododendron lace bug and signs of root rot. These are rhododendron concerns, without a known 'Landmark'-specific susceptibility.

Soil, drainage & water

Plant in acidic, well-drained soil. Keep the root area from staying saturated, and water during dry periods so its shallow roots do not dry out.

A little care goes a long way

Growing well, season after season.

Prune after flowering if shaping is needed. Check leaves periodically for lace bug stippling and dark deposits underneath.

Know what to look for

Symptoms can have more than one cause. These notes are a starting point for observing your plant and improving its growing conditions.

Rhododendron lace bug

Pale stippling above the leaves and dark, crusty deposits beneath them; repeated infestations can cause yellowing.

Place in partial shade and check leaf undersides. Dislodge nymphs with water or remove insects by hand.

Phytophthora root rot

Stunted growth, yellowish-green leaves, wilting or branch dieback, often with rotted roots.
