Bloom Report - August 20
Updated: Aug 31, 2022
Common Sunflower is today’s featured flowering plant. The Common Sunflower is flowering now in the Tule River Native Plant Demonstration Gardens in Porterville and along roadways and untended areas on the valley floor in Tulare County. Don’t overlook this valuable native plant just because it is common. It can also be a spectacular performer in the garden if given plenty of room, direct sun, and normal garden watering.
Consider using it as a fast-growing one-year hedge or division between areas in the garden. The Common Sunflower is an annual which grows quickly to 5 to 8 feet with fifty or more flowers on each plant. You will be rewarded with an amazingly fast-growing plant with a high branching habit. Butterflies including the Monarch use the nectar of the flowers. When the flowers fade, small birds such as the Lesser Goldfinch flock to the seed heads to feast on the abundant seed. It is amazing to see these small birds hanging upside down on the swaying branches to gather seed, which is available to be purchased online from Theodore Payne Foundation (store.theodorepayne.org) or can be gathered from mature plants. Only collect seed if you have permission and never from the wild. If you collect flower heads, separate the seed from one or two spent flowers and store the dry seed in a sealed, labeled container in your refrigerator until the spring. When the weather warms in the spring, plant the seed and cover lightly with soil. Do not cover with compost or woodchips. Alternatively, you can germinate the seed in small pots and plant them out in your garden as young plants. Sunflowers will need watering if there are no consistent spring rains. This is a great plant for a children’s garden because of the quick growth and impressive flower display. The sunflower will self-seed in the following years.
The sunflower is the ancestor of our commercial sunflowers and the sunflower seeds which we eat. This plant has been cultivated prior to Aztec times and has many uses both to people and animals. The Russians developed the single large-headed sunflower which is now widely used for oil, seed, and feed.
Maintenance is super easy. The most important task is to plant it where it has room to grow. The Common Sunflower can in one year grow up to eight feet tall and six or more feet wide. Thin the young plants so that they are three feet apart. After the birds have feasted on the seeds, the stalks can easily be pulled out. Sunflowers do best in full sun with weekly watering when they are young. Their root systems are shallow, if grown as a single plant, they benefit from staking. In nature, they tend to grow as a clump of plants.

The Tule River Parkway is a City of Porterville public park which features a three-mile paved walking and bicycle path. The gardens were planted and maintained by volunteers with project management by the Tule River Parkway Association. We have three volunteer garden days each month. Follow Tule River Parkway Association on Facebook for announcements. Volunteers are welcome to join us to care for the gardens on September 3, 15, and 17, from 8 am till 10:30 am. TRPA is holding a special event on Sunday, September 11, 2022. The event will include a docent lead walk of the gardens at 9 am and a milkweed giveaway to home gardeners at 10 am. The event will be held at the Jaye Street parking lot across the street from Harbor Freight on Jaye Street in Porterville.
