Standard Vs New Guinea
Standard impatiens are easy to grow and are generally smaller than New Guineas. They prefer shady areas and become carpeted mounds of color. They can become leggy over the summer, so it is good to pinch or scissor them back and they will flush back up again in a week or two.
New Guinea Impatiens and standard Impatiens will give you an amazing show all summer long in a huge array of colors from partial to full shade. They both love water so keep them moist but not soggy. Use well-drained soil and mulch the top of the soil around the plants to retain moisture. Fertilize often or use a slow-release fertilizer.
