Many people ask us – what are the longest-blooming annuals to use for containers, window boxes, and beds? Something that will flower continuously right up to fall. Here are the plants we recommend for prolific blooms, month after month. Now, the trick to getting most of these plants to give you that extra oomph in their performance is to fertilize them every two weeks with a diluted liquid fertilizer, and pinch them back when they get leggy, and this will spur reblooming as well. Here are our top picks:
Proven Winners Supertunias (Petunia) – (Requires deadheading and pruning)
Proven Winners Superbells (Calibrachoa, Million Bells) – these do not like being planted in the ground. Containers and window boxes only.
Geranium (Requires deadheading)
Sweet Alyssum (Lobularia)
Proven Winner’s Diamond Frost Euphorbia
Marigold (Requires deadheading)
Zinnia (Requires deadheading)
Sunflower (Proven Winner’s Suncredible)
Dahlia (Requires deadheading)
