What Is Gaura ‘Siskiyou Pink’?
Gaura ‘Siskiyou Pink’ (botanically classified as Gaura lindheimeri or, under a more recent naming, Oenothera lindheimeri ‘Siskiyou Pink’ — also called wandflower or beeblossom) is a clump-forming perennial known for its airy, butterfly-like flowers. The rose-pink, four-petaled blooms emerge from deep maroon buds on slender, wiry stems, giving the plant a light, fluttery look in the garden. It was introduced by the Siskiyou Rare Plant Nursery in Medford, Oregon, and has become a fairly widely available cultivar in the nursery trade.
Is Gaura ‘Siskiyou Pink’ a Perennial or Annual?
Gaura ‘Siskiyou Pink’ is generally classified as a herbaceous perennial (our perennial vs. annual flowers guide covers how this distinction plays out for other garden flowers), hardy in roughly USDA zones 5 through 8 or 9 depending on the source — there’s some minor variation in the exact zone range cited across plant references, so it’s worth checking with a local nursery or extension office if you’re near the edge of its hardiness range. In climates colder than its hardy zone range, it may be grown as an annual instead, since it won’t reliably survive winter outside its hardiness range.
Light, Soil, and Water Needs
This gaura does best in full sun, and prefers sandy or loamy, well-drained soil — good drainage is generally described as essential for this plant. It’s notably drought-tolerant once established, thanks to a deep taproot, and generally needs only low to medium watering after its first season. One point worth noting: gaura tends to flop or become leggy when grown in soil that’s too rich or fertile, or in too much shade, so resist the urge to over-fertilize or plant it in a heavily shaded spot if you want a more compact, upright habit.
Planting and Spacing
Because of its taproot, gaura generally dislikes being transplanted or divided once established, so it’s worth choosing a planting spot you’re confident in from the start rather than planning to move it later. Mature plants are commonly cited as reaching roughly 2 to 3 feet tall and a similar width, so spacing plants with enough room to fill in — without overcrowding neighboring perennials — is generally a good approach. It pairs reasonably well with other full-sun, drought-tolerant perennials; for general guidance on companion planting principles, see this companion planting guide, which covers matching plants by sun and water needs.
How to Keep Gaura Blooming
Removing spent flower panicles (deadheading) is commonly recommended to help prolong the bloom period, since it redirects the plant’s energy away from seed production and toward new flowers. That said, gaura is generally described as low-maintenance and doesn’t require heavy or frequent deadheading the way some other perennials do — occasional shearing or tidying is usually enough to encourage a fresh flush of blooms.
Pruning and General Maintenance
Taller gaura plants, especially those grown in rich soil or partial shade, can become leggy and prone to flopping. Cutting the plant back by about half in late spring is a commonly suggested way to encourage a more compact, sturdy form and reduce flopping. Close planting near other perennials, or light staking, can also help support floppy stems if needed.
Does Gaura Come Back Every Year?
Within its hardy zone range, gaura ‘Siskiyou Pink’ is a perennial and should return from the same root system year after year, generally blooming from late spring into fall (bloom window estimates vary somewhat by source, roughly May through August to as late as October depending on climate). It can also self-seed if spent flowers are left in place through autumn, meaning you may see volunteer seedlings pop up nearby in subsequent seasons in addition to the original plant returning.
Pollinators and Deer Resistance
Gaura’s airy flowers are generally attractive to bees, butterflies, and hummingbirds, making it a reasonable choice for a pollinator-friendly bed (see our plants for a butterfly and pollinator garden guide for other species to pair it with). It’s also commonly described as generally resistant to deer and rabbits, though as with most “deer-resistant” plants, this isn’t an absolute guarantee — hungry deer may still sample a wide range of plants when other food is scarce.
FAQ
Is the gaura siskiyou pink a perennial or annual plant? It’s generally classified as a herbaceous perennial, hardy in roughly zones 5 to 8 or 9 depending on the source. Outside that hardiness range, it’s typically grown as an annual.
Will gaura come back every year? Yes, within its hardy zone range, it should return from its root system each year, and it may also self-seed if spent flowers are left on the plant into autumn.
How do you keep gaura blooming? Deadheading spent flower panicles can help prolong blooming, though this plant is generally low-maintenance and doesn’t need frequent deadheading compared to some other perennials.
Does gaura flower all summer? It generally blooms over a long stretch from late spring into fall, with exact timing varying by climate and source — roughly May through August in some references, extending into October in others.
