How to Start It
★ Recommended for beginners
The standard route — pick up trays of young plants in late spring, choosing downy-mildew-resistant or New Guinea types for reliability.
The go-to flower for SHADE: 'busy lizzie' blooms non-stop all summer in places too dark for most flowers, and it's self-cleaning (no deadheading needed — spent flowers just drop). It loves moist soil and bright-to-deep shade, wilting fast if it dries out. One caution: classic bedding impatiens suffered badly from downy mildew, so pick resistant strains or the tougher, sun-tolerant New Guinea types. Frost-tender, so plant out only once it's warm.

Growing Tips
- 1Shade and moisture are the whole story — give impatiens dappled to full shade and soil that never bakes dry, and they'll flower their hearts out where nothing else will.
- 2In containers, check water daily in warm weather.
- 3Choose downy-mildew-resistant varieties (or New Guinea impatiens, which also take more sun) to avoid the disease that once devastated this plant.
- 4Plant out only after all frost.

Harvesting
When to Pick
Blooms all summer in shade; self-cleaning, so no deadheading needed
How to Harvest
- 1Wonderfully low-maintenance: no deadheading required, as the plant drops its own spent flowers.
- 2The one essential is water — keep the soil consistently moist (containers especially dry out fast and the plants collapse dramatically, though they often recover after a good drink).
- 3Pinch young plants once to encourage bushiness.
- 4Feed lightly in pots for continuous bloom.
