Zexmenia

Year-round

Zexmenia is a low, mounding Texas native wildflower that covers itself in small yellow orange daisy flowers from spring through fall and barely needs any water once it settles in.

• Give it full sun, at least 6 hours a day, for the most flowers
• Space plants 18 to 24 inches apart since each one spreads into a rounded 1 to 2 foot mound
• In heavy black clay, plant it high on a slight mound or work in some coarse compost so water drains away from the crown; in the sandier soils west of the metro it drains fine on its own but will need more frequent water through its first summer while roots establish
• Once established it handles drought well and only needs supplemental water during extended dry spells
• Deadhead spent blooms by hand or with light shears through the growing season to keep new flowers coming

A tidy, ever blooming mound reads as a deliberate flower bed border rather than a wild patch, especially if you keep the edges lightly shaped.

Fall

Zexmenia keeps blooming into fall until the first hard freeze, and cooling temperatures with autumn rain often bring on one more strong flush of flowers.

• Continue deadheading through October and November to keep the mound tidy as blooming slows
• Hold off on any hard pruning until after the first freeze, mid November on average in North Texas
• Fall is a fine time to divide crowded clumps or add new plants since cooler weather is easier on new roots than summer heat
• Reduce watering as days shorten, natural rainfall is usually enough

Continued fall color when neighboring beds are fading helps this plant read as an intentional, cared for planting.

Winter

Zexmenia dies back to the ground after a hard freeze in a typical North Texas winter, and the root crown stays alive underground to resprout in spring.

• Leave the frozen brown stems standing through winter, they protect the crown from additional cold and can be cut back in late February
• Cut the whole clump back to about 4 to 6 inches once you see new spring growth starting at the base, not before
• During a severe Arctic outbreak, a light layer of mulch over the crown adds extra insulation but is usually not necessary in a mild winter
• No watering needed while the plant is dormant unless the soil goes bone dry for several weeks

Standing dead stems in winter are the plant's normal dormant look, not a sign of neglect. A quick note to neighbors or a small sign can help if that matters to your HOA.

Spring

Spring is the best time to plant zexmenia in North Texas, and established plants will already be leafing out and starting their first flush of orange yellow blooms.

• Plant new nursery starts after the last mid March frost so roots have the full growing season to establish
• Water new plantings two to three times a week for the first several weeks until you see new growth
• Cut back any winter damaged stems to healthy green growth once new leaves appear, usually by early April
• Skip fertilizer, this plant flowers best in average to lean soil

Fresh spring growth and early blooms make this a good time to trim the mound into a neat rounded shape that will hold through summer.

Summer

Summer is when zexmenia does its best work, blooming steadily through the 100 degree afternoons while needing very little water once it is established.

• Established plants (in the ground a full year or more) usually need no supplemental water except during multi week dry stretches
• First year plants still need a deep soak once a week during July and August heat
• Watch for bordered patch butterfly caterpillars feeding on the leaves, this is expected since zexmenia is one of their host plants, not a pest problem to treat
• Deadhead every week or two to keep flowers coming through the hottest months
