Year-round

Mexican bird of paradise is a fast growing, heat loving shrub with fragrant yellow flowers from spring through fall. It is native to Mexico and the far southern tip of Texas, not to the North Texas area, but it handles our full sun and dry spells well once it settles in.

  • Plant it in full sun. It flowers best with 6 or more hours of direct sun a day.
  • Give it room to grow 8 to 15 feet tall and equally wide, or train it into a small multi trunk tree by removing the lowest branches as it grows.
  • Water deeply once or twice a week for the first growing season to help roots establish, then taper off. Established plants tolerate long stretches without rain.
  • In heavy black clay soil, plant it high on a slight mound or work in compost so water drains away from the crown. In the sandier soils west of the metro, plan on watering it more often through its first summer.
  • Expect leaf drop and possible dieback to the ground in a hard freeze. It usually resprouts from the base once the weather warms.

Fall

Fall is a good second planting window for this shrub, and it keeps flowering into early fall as temperatures cool.

  • September through October is a good second planting window. Cooler air and still warm soil let roots establish before winter.
  • Blooming tapers off by October and stops with the first hard frost, usually around mid November.
  • Hold off on any major pruning in fall. Cutting now can push tender new growth that a freeze will kill.
  • Rake and remove fallen leaves and spent flowers from the bed as the plant slows down, so the area does not look neglected going into winter.

A clean, leaf free bed with no fresh pruning cuts keeps the shrub reading as tended, not neglected, as it heads into its dormant winter look.

Winter

This shrub is only marginally cold hardy in North Texas. A hard freeze can kill it back to the ground, but the roots typically survive and it resprouts in spring.

  • Before a hard freeze or arctic outbreak, cover the plant with a frost cloth or an old blanket down to the ground. Do not lay plastic directly on the foliage.
  • Mulch 3 to 4 inches deep over the root zone before the first hard freeze to protect the roots even if the top dies back.
  • If stems blacken and go limp after a freeze, leave them in place until spring. They help insulate the crown, and cutting too early can expose it to the next cold snap.
  • Wait until new growth appears at the base in spring, then cut all dead wood back to just above the live growth.

A blackened, freeze damaged shrub can look dead and out of place through winter. Visible fresh mulch and a frost cloth used during cold snaps signal it is a deliberately kept planting, not neglect.

Spring

Spring is the best time to plant this shrub in North Texas, after the mid March frost date, so roots have the whole growing season to establish before next winter.

  • Plant after mid March once the danger of frost has passed.
  • New spring growth from any winter dieback usually starts low on the plant. Wait to prune out dead wood until you can see where the live green growth is coming from, generally by late April.
  • Water newly planted shrubs 2 to 3 times a week through spring while roots establish.
  • The first flush of butter yellow, fragrant flowers typically opens in April and continues into early summer.
  • Mulch 2 to 3 inches deep around the base, kept a few inches back from the stems, to hold spring moisture.

Winter dieback can leave bare, cut back stems going into spring. A tidy mulch ring plus visible new leaf growth read as an intentional, tended planting rather than a dead shrub.

Summer

Once established, this shrub is one of the more heat and drought tolerant choices for a North Texas front yard, and it keeps blooming through the hardest part of summer.

  • After the first year, established plants need only occasional deep watering, roughly every 10 to 14 days, during 100 degree stretches with no rain.
  • Watch first year plantings closely in July and August. Their roots are not yet established, so they still need weekly deep watering.
  • Flowering continues through summer into fall. Deadheading is not required since the spent blooms are not showy enough to bother removing.
  • Skip fertilizer during peak summer heat. Feeding a heat stressed plant can push weak new growth that wilts in the afternoon sun.

Year-round

Mexican Bird of Paradise wants full sun, soil that drains well, and not much water once it settles in. It's a warm climate shrub built for zone 9 and up, so in Memphis plan on treating it as a plant that dies back most winters rather than a permanent evergreen hedge.

  • Give it a spot with at least 6 hours of direct sun a day. It blooms the most in full sun and gets thin and sparse flowering in shade.
  • Plant it in soil that drains well, sandy or loamy is ideal. It tolerates soil from slightly acidic to slightly alkaline, but it does not like sitting in wet clay.
  • Water new plants regularly through their first year to get the roots established. Once it's settled in, it handles dry spells well and only needs occasional deep watering.
  • In its normal range this grows into a rounded shrub or small tree, roughly 10 to 15 feet tall and close to that wide, so give it 8 to 10 feet of room from the house, fences, or other shrubs.
  • It does not respond well to heavy pruning. Shape it lightly to remove dead or crossing growth rather than shearing it.
  • Memphis sits in USDA zone 7b to 8a, well outside this plant's normal hardy range of zone 9 to 11. Expect it to freeze back to the ground in a typical Memphis winter, so it works better here as a die-back perennial or a large container plant you can move for winter than as a permanent landscape shrub.

Fall

Fall is about slowing down watering and getting the root zone ready for winter, not about pruning.

  • Taper off supplemental watering as growth slows and nights cool, usually starting in October in Memphis.
  • Skip pruning in fall. Cutting now can trigger new growth right before a freeze, and fresh growth is the most freeze tender part of the plant.
  • Before the first hard freeze, typically mid to late November in Memphis, spread 3 to 4 inches of mulch over the root zone, keeping it a few inches back from the trunk. Protecting the roots is what lets the plant come back even if the top freezes off.
  • If you're growing it in a container, this is the time to line up a spot for it to spend winter, like a garage or bright indoor room, since an unprotected potted plant will not make it through a Memphis freeze.

Skip fall pruning and just add mulch. An unpruned, mulched bed reads as intentional winter prep rather than a neglected shrub.

Winter

Winter is the real test for this plant in Memphis. Expect the top growth to freeze back most years, and treat that as normal rather than a sign the plant failed.

  • This shrub is rated hardy to roughly 15 to 20 degrees F for short dips, and it can lose leaves or die back to the ground well before that in a sustained hard freeze. Memphis winters regularly go colder than its comfort zone, so dieback most years is expected, not a mistake you made.
  • Leave frozen, blackened stems standing through winter instead of cutting them back right away. They help insulate the crown, and cutting too early opens the plant up to more cold damage.
  • Keep the fall mulch layer in place over the root zone, and add more after any hard freeze if it's washed thin. The roots surviving is what lets the plant regrow in spring even if everything above ground is gone.
  • If it's in a container, bring it into a garage, unheated sunroom, or bright indoor spot on any night with a freeze in the forecast.

Leaving winter-killed stems standing looks intentional when paired with a clean mulch layer, rather than like an abandoned shrub. Save the hard cutback for after the last frost in spring.

Spring

Spring in Memphis is cleanup and planting time for this one. Wait for frost danger to pass before you touch winter damage or put a new plant in the ground.

  • Wait until after Memphis's average last frost, mid to late April, before pruning off any winter damage. Cutting too early can expose fresh cuts to one more freeze.
  • If a hard winter killed the top growth, cut the dead wood back to live green wood, or all the way to the ground if nothing above ground made it. Established plants usually push new growth back up from the roots once the soil warms.
  • Spring is the best time to plant a new one here. It gives the roots a full warm season to get established before facing a Memphis winter.
  • New growth comes on fast once it starts. Hold off on fertilizer until you see healthy new leaves, then a light feeding is plenty.

Once frost risk passes, cut back the winter-killed stems promptly so the front bed doesn't sit looking dead into late spring.

Summer

Summer is when this shrub does its thing, blooming through Memphis's heat as long as it gets enough water to keep pushing new growth.

  • This is peak bloom season. Water deeply during long dry summer stretches to keep the flowers coming, but let the top few inches of soil dry out between waterings.
  • Full sun all summer is fine and actually pushes more blooms. It handles heat well since it comes from a warmer, drier climate to begin with.
  • Deadhead spent flower spikes if you want a tidier look and less reseeding, but it's not required for the plant's health.
  • Check new growth for aphids or spider mites during hot, dry stretches. A strong spray of water from the hose usually knocks them back without needing anything else.
