Hi Brigitte,

Will you be able to provide water regularly to these planters? How much direct sun will the flowers growing in the planters receive? What are the dimensions of the planters? How deep are the planters? And, as John asked, do you want annuals, perennials, shrubs or vines. I'll give some recommendations if you can provide me with these details.

Answer #1 · Maple Tree's Answer · Hi Brigitte-Knowing a little about your planters would help myself and others come up with a few plants you may like to try. Are you looking for annuals for summer color? Maybe perennial shrubs or groundcover that will last year round. Are the planters in some shade or full sun? Are the planters small or large (dimensions) and is there any height or width requirments other than that which could conseal the mailbox confusing the mailman.

In Gardenality you can search out plants and keep a list of ones you may want to try or at least look at when going to the nurseries or garden centers. This plant search tool is great whether you know the name of the plant you are looking for or just wanting to find plants that meet your requirements for a certain location in the garden. Its not only a valuable tool, but fun to use also. I have noted the link below that will show you how to use this plant search tool. Just click on the link to go directly to the article.


You mentioned the Sonata mix cosmos. This is really a great annual and one that would give an abundance of color out front in a mailbox planter from spring to the first frost in the fall. Most mail boxes are situated in locations that don't have the most desirable soil and irrigation. Many times it is an area that gets full hot sun all day long. Well, this is perfect for Cosmos. They are not particular about most soil types, have low water needs, and love the sun. If your planters have more desirable conditions, even the better. You can seed or plant cosmos now if no more frost is expected or early spring for late spring-early summer blooms. In mid summer or when flowering diminishes you can trim them down to 12 to 18 inches high. They will regrow quickly and be back blooming in a month for color all the way to fall. Besides Sonata Mix colors of white, rose, and pink the Cosmic Mix of red, orange, and yellow is also beautiful. There are other varieties with different flower colors also that may be available at your local nurseries. I have noted two links to the Gardenality plant files for cosmos below. Clicking on the links will take you directly to the plant files to see information and pictures of the cosmos. Hope this has helped with your question.
