Impatiens 'Expo Cherry'

Vigorous, mound-forming annual growing up to 25cm.

Single 5-petalled cherry red flowers are held nicely above the lush green foliage and are produced summer long. Frost tender.

Impatiens can handle full sun to full shade. They prefer moist, well-drained soil but will tolerate wetter soils (not standing water) and some drying out.

Soil should be well-drained and friable. It is advisable to annually apply lime to the soil and add organic matter such as compost every second year. Prior to planting, rake general-purpose fertiliser into the soil at about 100 grams (about 2 handfuls) per square metre. Transfer seedlings outdoors to become hardened before planting. Plant at the same depth at which the plants were growing in their container, as planting too deeply usually results in failure. Handle carefully to minimise root disturbance. If bushy growth habit is desired, remove the growing tips from the seedlings when planting. Water immediately after planting. Shelter plantings from strong winds and protect from frost.

Deadhead flowers to prolong the flowering season. Fertilise fortnightly with a liquid feed high in potash to help prolong flowering.

Impatiens can be propagated by seed. This can be sown either in trays or pots or sown directly where they are to flower outside. Busy Lizzies often seed out on their own, especially if the surrounding soil is moist and shady. Because of this, they may become weedy in some gardens. They can also be easily grown from cuttings.

It is highly tolerant of urban pollution and will even thrive in inner-city environments.
