In this guide, we'll compare everything you need to know about denver daisy vs black-eyed susan so you can pick the perfect flower for your garden.
What is a Denver Daisy?
The Denver Daisy (Melampodium leucanthum) is a compact perennial that's native to the southwestern United States and Mexico. It's sometimes called Blackfoot Daisy because it grows in rocky, dry areas where Blackfoot tribes once lived.
This little plant grows low to the ground, usually staying under 12 inches tall. It produces tons of small white flowers with yellow centers throughout the growing season. The flowers are about 1 inch across and have a sweet, honey-like scent.
Denver daisies love hot, dry conditions. They're perfect for xeriscaping, which means landscaping that doesn't need much water. These tough little plants can handle drought, poor soil, and intense heat without complaining.
What is a Black-Eyed Susan?
Black-Eyed Susan (Rudbeckia hirta) is one of America's most recognizable wildflowers. It's native to most of North America and has been a garden favorite for generations.
These flowers are bigger than Denver Daisies in every way. Black-eyed susans grow 2 to 3 feet tall with flower heads that can be 2 to 3 inches across. The petals are golden yellow or orange-yellow, and the center cone is dark brown or black, which gives the flower its name.
Black-eyed susans are technically short-lived perennials, but many gardeners treat them as biennials or even annuals. They self-seed easily, so once you plant them, they'll probably come back year after year on their own.
According to gardening experts at Big Write Hook, both flowers are excellent choices for beginner gardeners becuase they're so forgiving and easy to grow.

Size and Growth Habit Differences
When comparing denver daisy vs black-eyed susan, size is probably the most obvious difference you'll notice.

Water and Maintenance Requirements
Looking at denver daisy vs black-eyed susan maintenance needs, both are considered low-maintenance plants, but there are differences.
Denver daisies are extremely low maintenance once established. They actually suffer if you water them too much or give them rich soil. After the first growing season, you can basically ignore them. Just trim them back in late winter if they look messy. No deadheading is really necessary, though it can encourage more blooms.
Black-eyed susans need a bit more attention. They appreciate regular watering, especially during hot, dry spells. Deadheading spent flowers keeps them blooming longer and prevents excessive self-seeding. You'll want to cut them back to the ground in late fall or early spring.
Neither plant needs much fertilizer. Both are actually happier without it.
Wildlife and Pollinator Benefits
Both plants in the denver daisy vs black-eyed susan comparison are excellent for attracting beneficial wildlife to your garden.
Denver daisies attract native bees, butterflies, and other small pollinators. Their long bloom season provides nectar and pollen from spring through fall. The low growth habit creates shelter for ground-dwelling beneficial insects.
Black-eyed susans are pollinator magnets. They attract butterflies, bees, and even hummingbirds occasionally. In fall and winter, goldfinches and other birds eat the seeds from the dried flower heads. Many gardeners leave the spent flowers standing for this reason.
Deer and rabbits generally avoid both plants, which is a big plus if you have problems with these garden pests.
