Geum chiloense
Geum brings bright red-orange flowers on wiry stems above a low clump, giving a border a lively lift from late spring into midsummer. At about 2 feet tall, it reads best as a mid-border perennial rather than an edging plant. Its long bloom period and pollinator-friendly flowers make it useful in repeated pockets through a sunny planting.
Space Geum 18 inches apart, measured center to center (45 cm).
The mature spread is about 18 inches (45 cm), so neighboring plants just meet at maturity without crowding.
Treat 18 inches as a planning baseline — cultivar and local growing conditions shift the final footprint.
Set geum in the front half of a mixed border, behind low edging plants and ahead of taller summer perennials. Repeat it in small groups or a loose ribbon so the flower stems punctuate the bed without forming a continuous wall. Keep it within easy reach from a path or bed edge: regular deadheading can extend the floral display, and the compact clump leaves room for neighboring plants to develop.
Allow about 18 inches of width for each mature clump, then plant on 18-inch centers. At that distance, neighboring plants will meet into a filled planting while retaining distinct crowns for maintenance. In a narrow border, use a single staggered row; in a deeper bed, offset rows rather than aligning plants directly behind one another for a more even footprint.
Use geum where it receives full sun and can be watered through dry spells to maintain moderate, even moisture. A moist but well-drained position suits it better than a spot that stays wet in winter. Reserve the plant for beds with workable drainage rather than low pockets beside paving, downspouts, or compacted heavy soil.[1][2]
The main show runs from late spring through midsummer, when the wiry flowering stems rise above the foliage. Deadhead as flowers fade to encourage further bloom, then remove old flower stems after the display. Leave enough circulation around each clump to reach spent stems without treading into the planting.[1]
Avoid crowding geum between vigorous spreaders or tightly against woody shrubs, where access to the crown becomes difficult. Clumps benefit from division every few years to prevent congestion, so leave a workable gap at the bed edge or between neighboring perennials. In hot, humid summer climates, choose a site that does not become dry and stressed.[1][2]
