The best time to plant impatiens flower (https://abodelook.com/knowledge-hub/impatiens-flower/) is after the danger of frost has passed and temperatures are consistently mild. They thrive in warm growing conditions but can struggle in extreme heat or cold. In suitable climates, impatiens can be planted during spring for a long season of colorful blooms. Choose a location with appropriate shade and well-draining, moisture-retentive soil.
