Astrantia beside roses
Practical compatibility, planting, care and climate limits, without exaggerated promises.
Why it makes a good neighbour
Delicate star-shaped flower heads soften the large blooms of roses and work especially well in romantic plantings and light shade.
How to plant it beside a rose
It grows best in fertile soil that holds moisture but does not waterlog. It is a good neighbour for roses in a site that is not too dry.
Choose the cooler side
In a hot garden, plant it on the east side of the rose.
Keep the soil moist
Mulch, without covering the base of the plants.
Do not crowd them
Leave air between the astrantia foliage and the rose.
Cut off spent flower heads
This keeps the planting tidy and prolongs flowering.
For Ukraine and Europe
Short care calendar
Spring
Mulch, and divide an old clump if needed.
