Prinses Juliana Geum

Geum x hybrida 'Prinses Juliana'

The Story

Plant Bio

Geum is a genus of clump-forming herbaceous perennials in the rose family, characterized by basal rosettes of pinnate foliage and wiry flowering stems. These plants thrive in cool-temperate climates, requiring consistently moist but sharply drained soils to prevent crown rot during winter dormancy.

'Prinses Juliana' is a historical Dutch cultivar distinguished by its semi-double, ruffled flowers of a rich fiery orange with prominent golden-yellow stamens. The blooms emerge in loose cymes from late spring through late summer on upright stems reaching up to 24 inches above the bright green foliage mound.

Uses & Benefits:

Produces vibrant, semi-double orange flowers on wiry stems that contrast well with the dense, green basal foliage.

Functions as an effective, low-growing border edging or container plant in cool-temperate regions.

Attracts native bees, generalist pollinators, and beneficial insects to the garden.

Planting

How to Grow

Select a planting site with full sun to partial shade, ensuring afternoon shade in hot summer regions.
Amend heavy clay or sandy soils with organic matter to create a fertile, humus-rich loam.
Plant the crown level with the soil surface, ensuring the drainage is excellent to prevent winter waterlogging.
Water regularly to keep the soil evenly moist, avoiding complete drying out during the active growing season.

Pro Tip

Avoid over-potting or planting in heavy, unamended clay, as winter wetness in poorly drained soil invariably induces fatal root rot.

Care Guide

Do

Deadhead spent flower stems down to the basal foliage to encourage sporadic rebloom.
Divide established clumps every two to four years in spring to maintain plant vigor.
Apply a light top-dressing of compost or a balanced organic fertilizer once a year in spring.

Don't

Do not plant in low-lying areas or heavy clay where water collects during winter.
Do not cut back into old, leafless woody parts of the crown when tidying the plant.
Do not divide the clumps annually, as they flower best when allowed to form a tight, congested crown.
