To grow kiss me over the garden gate, give this annual full sun, rich moist soil, and steady water, and sow seeds after frost for tall summer blooms.
Kiss me over the garden gate is an old cottage flower with tall, arching stems and long wands of rosy blooms that sway above the border. Once you understand what this plant likes, you can raise it from seed every year.
What Is Kiss Me Over The Garden Gate?
Kiss me over the garden gate, botanically known as Persicaria orientalis and sometimes sold as prince’s feather, is usually grown as a warm season annual. In one season it can reach 4 to 7 feet tall with pendent spikes of pink, magenta, or white flowers that appear from mid summer into fall.
The plant has broad, green, slightly rough leaves on sturdy, upright stems. It thrives in full sun with evenly moist soil and will usually bloom until frost, drawing hummingbirds and other pollinators to the garden.
Garden guides such as the Cornell University flower growing notes describe this plant as an annual that prefers rich, moist, well drained soil and a sunny position for best height and flowering. In many regions it reseeds freely, so you often see new seedlings nearby in later years.

How To Grow Kiss Me Over The Garden Gate Step By Step
Once you follow a simple routine, How To Grow Kiss Me Over The Garden Gate turns into a habit you can repeat every spring for tall, reliable color.
Choosing The Right Site
Pick a sunny position along a fence, gate, or the back of a border where tall stems will not shade shorter plants. Full sun keeps the growth sturdy and reduces flopping. In windy gardens, a spot with some shelter from strong gusts helps the long flower wands stay upright.
The soil should drain well yet hold moisture. Dig in several inches of compost or well rotted manure before planting. This adds nutrients and improves both heavy clay and light sandy ground.
Starting Seeds Indoors
Starting seeds indoors gives you a head start and taller plants. Many growers chill the seed for several weeks to mimic winter, which can improve germination rates.
- Ten to twelve weeks before your last spring frost, place seeds in a small paper packet inside a sealed jar or plastic box and refrigerate them for three to six weeks.
- Six to eight weeks before your last frost date, fill small pots or cell trays with seed starting mix, water until evenly damp, and sow one or two seeds per cell.
- Cover very lightly with mix, no more than one quarter inch deep, since the seeds do better near the surface.
- Set the trays in a warm spot around 65–75 °F and keep the mix just moist. Germination may take one to three weeks.
- Once seedlings appear, move them under bright lights or into a sunny window so they grow stout instead of weak and stretched, and thin to one per cell.
Direct Sowing In The Garden
If you prefer less indoor work, you can sow the seed directly where the plants will grow. This method often leads to slightly shorter plants but still plenty of bloom.
- Wait until all danger of frost has passed and the soil has warmed.
- Rake the bed to a fine texture, removing clumps and debris.
- Sow seeds about 12 inches apart, cover with a thin layer of soil, and water with a soft spray.
- Keep the top inch of soil evenly moist until seedlings appear.
- When plants are a few inches tall, thin them to 18 to 24 inches apart so each one has space to reach full size.
Transplanting Seedlings Outdoors
Harden off indoor grown seedlings for a week before planting by gradually giving them more time outdoors each day. On planting day, set each seedling at the same depth it grew in the pot, spacing them 18 to 24 inches apart, water well, and add a light mulch layer around, but not touching, the stems.
Season By Season Care For Kiss Me Over The Garden Gate
Watering And Feeding
Kiss me over the garden gate enjoys steady moisture, especially during hot spells. Water deeply when the top inch of soil feels dry so roots grow down rather than staying near the surface. In fertile soil the compost you added at planting time often provides enough nutrition for the season; in lean ground, a light spring application of balanced, slow release fertilizer supports strong growth without creating weak, overly lush stems.
Staking And Managing Tall Stems
In a calm, sunny garden many plants stand well on their own. Where wind is common, placing a simple grid of bamboo canes and natural twine early in the season gives the clump something to lean on later, or you can plant it behind a fence or shrub that acts as a living support.
If stems start to lean across a path, tie them gently to a stake rather than cutting them back, since pruning can reduce flowering. Late in the season, removing browned or broken stems keeps the planting tidy while new spikes continue to open.
Deadheading And Self Seeding
Each flower spike carries many tiny blooms that mature into seeds, which often drop and sprout the next spring. If you want volunteer seedlings, leave several spikes on each plant until they dry and shatter. If you prefer a more controlled planting, trim spent spikes before they fully set seed.
Guidance from the NC State Extension plant database notes that this species may self sow and even behave in an invasive way in parts of the southeastern United States, so seed control matters in those areas.
| Season | Main Tasks | Care Tips |
|---|---|---|
| Late Winter | Chill seeds in the refrigerator | Seal dry seed in a packet inside a jar to prevent moisture |
| Early Spring | Start seeds indoors or prepare beds for direct sowing | Add compost, set up stakes or supports, and plan spacing |
| Late Spring | Transplant or thin seedlings and water regularly | Mulch after planting to conserve moisture |
| Summer | Maintain watering, monitor for pests, enjoy blooms | Tie in any leaning stems and remove damaged growth |
| Late Summer | Decide whether to allow self seeding | Leave some spikes for seed or deadhead to limit spread |
| Fall | Collect seed, cut back spent plants after frost | Label saved seed and tidy beds for next season |
| Early Next Spring | Watch for volunteer seedlings | Transplant extras or thin where they are too dense |
Common Problems And Simple Fixes
Plants Leaning Or Flopping
Leaning stems often point to shade, rich nitrogen, or strong wind. If plants stretch toward light, trim back nearby shrubs or move future plantings to a brighter spot, and tie floppy stems to a stake with soft ties while keeping fertilizer modest.
Pests And Diseases
Kiss me over the garden gate has few serious disease problems when grown in airy, sunny conditions. Good spacing and watering the soil instead of the leaves limit issues such as mildew on crowded plants.
In some regions the foliage can attract Japanese beetles, which chew the leaves and flower spikes. Hand pick beetles in early morning and drop them into soapy water, or use row covers on young plants, and avoid broad spectrum insecticides that can harm pollinators.
Poor Germination Or Slow Growth
If few seeds sprout, check whether they had a cold period before sowing and whether the seed was buried too deeply. This species responds well when seed has several weeks in the refrigerator before sowing near the soil surface.
Slow seedlings may lack warmth or light. Raise the soil temperature with a heat mat during germination and move trays to a brighter location as soon as green shoots appear. Outdoors, growth speeds up once the weather turns reliably warm.
Design Ideas With Kiss Me Over The Garden Gate
This tall annual fits neatly into many garden styles. For a cottage look, plant a drift behind lower perennials such as phlox, hardy geraniums, or shasta daisies, and let the airy, drooping flower spikes form a soft curtain over picket fences and arbors.
In a mixed border, use kiss me over the garden gate as a vertical accent near the back, weaving stems through shrub roses or tall grasses. Because it reseeds, you can allow a small group to move slightly from year to year until it finds the pockets that suit your soil and light.
Cutters value the long stems for fresh arrangements and for drying. Harvest spikes when most of the tiny flowers are open, strip the lower leaves, and place the stems in water or hang bunches upside down to dry. With a little planning and the steps above, you can answer the question of How To Grow Kiss Me Over The Garden Gate with your own beds filled with tall, swaying blooms.
