Growing Impatiens
In full or partial shade gardens, impatiens flower like mad from early summer to the first frost.
Watch video
  • Impatiens may be grown from seed sown early indoors and transplanted outside after frost, or sown directly in the garden after frost.

    Sowing Seed Indoors:

    • Sow indoors 8-10 weeks before last frost using a seed starting kit. Sow seeds shallowly lightly covered with fine seed starting soil.
    • Keep the soil moist at 70-75 degrees. Impatiens can benefit with bottom heat.
    • Seedlings emerge in 18-28 days.
    • As soon as seedlings emerge, provide plenty of light on a sunny windowsill or grow seedlings 3-4 inches beneath fluorescent plant lights turned on 16 hours per day, off for 8 hours at night. Raise the lights as the plants grow taller. Incandescent bulbs will not work for this process because they will get too hot. Most plants require a dark period to grow, do not leave lights on for 24 hours.
    • Thin to one seedling per cell when they have two sets of leaves.
    • Seedlings do not need much fertilizer, feed when they are 3-4 weeks old using a starter solution (half strength of a complete indoor houseplant food) according to manufacturer’s directions.
    • Transplant hardened-off seedlings to the garden after the frost.
    • Before planting in the garden, seedling plants need to be “hardened off”. Accustom young plants to outdoor conditions by moving them to a sheltered place outside for a week. Be sure to protect them from wind and hot sun at first. If frost threatens at night, cover or bring containers indoors, then take them out again in the morning. This hardening off process toughens the plant’s cell structure and reduces transplant shock and scalding.

    Planting in the Garden:

    • Select a location in full to part shade with good rich moist organic soil. New Guinea Impatiens may be planted in full sun.
    • Prepare the bed by turning the soil under to a depth of 8 inches. Level with a rake to remove clumps of grass and stones.
    • Most plants respond well to soils amended with organic matter. Compost is a wonderful form of organic matter with a good balance of nutrients and an ideal pH level, it can be added to your planting area at any time. If compost is not available, top dress the soil after planting with 1-2 inches of organic mulch, which will begin to breakdown into compost. After the growing season, a soil test will indicate what soil amendments are needed for the following season.
    • Plants should stand 12 inches apart in the garden.
    • Dig a hole for each plant large enough to amply accommodate the root ball.
    • Set level with the surrounding soil. Fill with soil to the top of the root ball. Press soil down firmly with your hand leaving a slight depression around the plant to hold water.
    • Water thoroughly, so that a puddle forms in the saucer you have created. This settles the plants in, drives out air pockets and results in good root-to-soil contact.
    • Use the plant tag as a location marker.
    • Water thoroughly, so that a puddle forms in the saucer you have created. This settles the plants in, drives out air pockets and results in good root-to-soil contact.
    • Keep weeds under control during the growing season. Weeds compete with plants for water, space and nutrients, so control them by either cultivating often or use a mulch to prevent their seeds from germinating. 
    • Mulches also help retain soil moisture and maintain even soil temperatures. For annuals an organic mulch of shredded leaves lends a natural look to the bed and will improve the soil as it breaks down in time. Always keep mulches off a plant’s stems to prevent possible rot.
    • Keep plants well-watered during the growing season, especially during dry spells. Plants need about 2" of rain per week during the growing season. Use a rain gauge to check to see if you need to add water. It's best to water with a drip or trickle system that delivers water at low pressure at the soil level. If you water with overhead sprinklers, water early in the day so the foliage has time to dry off before evening, to minimize disease problems. Keep the soil moist but not saturated.
    • Until plants become established, some protection from extreme winds and direct, hot sunlight may be necessary. Good air movement is also important.
    • After new growth appears, a light fertilizer may be applied. Keep granular fertilizers away from the plant crown and foliage to avoid burn injury. Use low rates of a slow release fertilizer such as Flower-tone, as higher rates may encourage root rots.
    • Monitor for pests and diseases. Check with your local Cooperative Extension Service for pest controls recommended for your area.
    • Remove plants after they are killed by frost in fall to avoid disease issues the following year.
    • Impatiens make beautiful temporary groundcovers in shade gardens. They also can be planted among shade-loving perennials, such as hostas, to bring summer-long color to shady flower beds. Plant them in large drifts and let them fill in, or use them as edging plants along walkways, terraces, or at the front of a bed or border.
    • Impatiens make fine additions to container plantings. In fact if you have experienced downy mildew in the past, container growing in fresh commercial potting soil is the only way you can grow impatiens (other than New Guinea impatiens).
    • Hummingbirds, butterflies, and other beneficial insects love to visit impatiens.
    • New Guinea impatiens can take the sun, but be careful to not allow plants to dry out.

  • Impatiens, (New Guinea) Spreading Corona is rated 5.0 out of 5 by 3.
    Rated 5 out of 5 by from Unbelievable! These are the most amazing annuals I've ever had, bar none. As of September 6, these plants are still looking picture-perfect. It's like they have been frozen in their peak of full bloom all summer, a solid mound of perfect bright blooms. They don't go through phases of bloom like other New Guineas. I have them on the northeast side of a bed. They are only shaded in very late afternoon; full sun the rest of the day. The picture shows a group of five. I will plant a lot more next summer! Please offer them as live plants every year!

    Rated 5 out of 5 by from Beautiful!!! I planted three plants in a large white pot on my north-facing balcony in May. The plants are absolutely beautiful and have been the focal point of my deck all summer. Beautiful color, self-cleaning blooms, and lovely dark foliage. I'll definitely plant these again next year.

    Rated 5 out of 5 by from Alluring !!! I have gotten so many compliments about the color and fullness of the Spreading Corona. When I received them, they were packed very well but scrawny with just a couple tiny leaves. I don't do anything special to them and they're gorgeous. These pictures really don't do them justice.
