Our native plant of the month is Coreopsis tripteris, native to central and southeastern United States where it is found in prairies, dry open woods, along roadsides and railroad tracks. It is also easy to grow here on Long Island, even in poor, sandy and rocky soils. Tolerant of drought, heat and humidity, this tickseed grows best with some moisture and fertility, often growing 8 feet tall and blooming from July through early October.

Its golden yellow flowers with brown centers are held high on tall stems. These mature to clusters of brown seeds, which are relished by birds and can form large colonies of tickseeds over time.

Introduced by Mt. Cuba, ‘Gold Standard’ is a variety I selected because it consistently grows 5-6 feet tall, has an extra-long blooming period and extra sturdy stems that hold up well against strong winds.

Another member of the daisy family that blooms late in the season is Rudbeckia ‘Autumn Sun.’ Like the tickseed above, it is tall and grows in dry to average soils in full sun. Flowers are 3-4 inches across, have drooping golden yellow ray petals and tall, green central cones that become food for overwintering birds.

Look for both of these native plants in local garden centers and get your plants into the ground soon. They’ll be a pleasing addition to your sunny garden next year.
