If you want to ensure that butterflies, hummingbirds and other nectar feeders can find plenty of food in your backyard from late summer into fall, now is the time to sow a late crop of zinnias and Mexican sunflower seeds.
Currently the gardens of most Georgians that plant for pollinators are awash with color and food (pollen and nectar). However, by late September and October many of these same beautiful pollinator havens will be far less colorful and offer hummingbirds, butterflies and other pollinators less food. In spite of trying to prolong the blooming period of cut-and-come-again plants, the numbers of flowers being produced will often dwindle by late summer. Other flowers will have simply ended their blooming period and will not blossom until next year.
This situation can cause problems for all pollinators, including migrants making their way south on their fall migrations. This list of migrants includes several butterflies such as the monarch as well as ruby-throated hummingbirds.
One way you can assist these critters this year is to plant more zinnias and Mexican sunflowers. Since both plants require somewhere from 60-70 days to go from seed to flower, you need to plant seeds for these plants right now.
Both can be planted in beds. I can personally attest to the fact that zinnias also do extremely well in containers.
Long-tailed Skipper nectaring on Mexican Sunflower
Since my wife and I have never planted Mexican sunflowers in containers, I don’t know how they do in that situation. I suspect because they grow so tall, they would more than likely require staking.
Last year my wife and I enjoyed great success planting a second crop of zinnias. They attracted many butterflies, including monarchs, and hummingbirds. In addition, they added needed splotches of late color to our gardens.
If you decide to try this practice, I think you will be pleased with the results. I know monarchs, ruby-throated hummingbirds, and scores of other pollinators will benefit from your efforts.
