Ground-plum

Year-round

Ground plum milkvetch is a low, sprawling native prairie legume that's easy-care once it's settled into Fort Worth's clay and heat, with one thing to flag around horses.

• This species is native to Texas prairies, including the black clay prairies of North Central Texas, so it already matches Fort Worth's alkaline soil and hot, dry summers.
• Give it full sun to part shade and well-drained soil. It handles both dry spells and normal rainfall once it's established, so it doesn't need a special watering routine.
• The low, spreading plant tops out around a foot or two tall and spreads wider than it grows up, which makes it a good low border or rock garden filler rather than a tall accent plant.
• Keep grazing horses away from it. ASPCA lists loco weed, the Astragalus group this plant belongs to, as toxic to horses. It is not on the ASPCA's dog and cat toxic plant lists.

Fall

Fall is quiet and low-maintenance. A light cleanup is optional, not required.

• The foliage naturally browns and dies back to the crown with the season's first cool snaps, typically by November in North Texas.
• You can cut the dried stems back close to the ground once they've browned if you want a neater bed. Leaving them standing through winter won't hurt the plant either.
• A light cleanup that leaves a few dropped seed pods on the ground helps the plant reseed on its own for more plants in future years.
• There's no need to fertilize or water going into fall. The plant is winding down on its own schedule.

Cutting the browned stems back once they've dried keeps a front bed looking tidy through fall, though it isn't required for the plant's health.

Winter

Winter is a full dormant period. There's bare ground where the plant was and nothing to do until it resprouts.

• The plant is leafless and dormant at the crown through winter, so don't be alarmed by the empty-looking spot in the bed.
• No supplemental water is needed for an established plant. North Texas's normal winter rainfall is enough on its own.
• Cold isn't a concern here. This species' native range reaches north through Kansas, the Dakotas, and into Canada, so Fort Worth's winter lows are mild by comparison.
• New growth and the first flower buds typically start showing again in late winter, often by February, ahead of most other prairie plants nearby.

The bare winter look can leave a visible gap in a front bed, so nearby mulch or a winter companion plant helps if a tidy appearance matters.

Spring

Spring is the showy season, with early pink-purple blooms and the first plum-shaped pods, and almost no work required from you.

• Flowers open earlier than most prairie wildflowers, often by late February or March in North Texas and continuing into April.
• Skip fertilizer. This plant is a legume that fixes its own nitrogen in the soil, so feeding it just encourages floppy growth instead of more flowers.
• Only water if spring turns unusually dry for several weeks straight. Fort Worth's normal spring rain is typically enough for an established plant.
• After the flowers fade, look for the pods to swell up green and round, looking like small plums, before they ripen toward early summer.

Summer

Summer is a rest period. The plant has already bloomed and mostly needs to be left alone through Fort Worth's heat.

• Once Fort Worth's summer heat really sets in, the foliage can look tired or start to die back some. That's normal dormant behavior for this plant, not a sign of a problem.
• Hold off on extra water unless the summer turns into a multi-week drought. Too much water in heavy clay during summer is more likely to rot the roots than help the plant.
• There's no deadheading or pruning task in summer since the plant has already set its seed pods for the year.
• If you want to save seed, collect the pods once they've turned a dusty purple and gone slightly soft, usually by early summer, before ground squirrels and mice get to them first.

Year-round

Ground plum milkvetch is a low native prairie legume that's genuinely at home in Dallas's Blackland Prairie clay, with one thing to flag around horses.

• This species is native to the Blackland Prairie that Dallas sits on, documented growing wild in nearby Collin County's remnant prairies as one of the area's characteristic native legumes.
• It grows fine in Dallas's heavy black clay as long as the spot drains reasonably well. It tolerates both dry spells and normal rain once established, so it doesn't need a dedicated watering schedule.
• The plant stays low and spreads out sideways, usually under 2 feet tall, which makes it a good filler for a native front bed rather than a tall focal plant.
• Keep grazing horses away from it. ASPCA lists loco weed, the Astragalus group this plant belongs to, as toxic to horses. It is not on the ASPCA's dog and cat toxic plant lists.

Fall

Fall brings die-back and an optional light cleanup, nothing more.

• Foliage browns and dies back to the crown with the season's first cool snaps, typically sometime in November in the Dallas area.
• You can cut the dried stems back near the ground once they've browned for a tidier look, or leave them up through winter since either way is fine for the plant.
• Letting a few ripe pods drop and stay on the ground during fall cleanup helps the plant reseed itself for more plants down the road.
• No fertilizing or extra watering is needed going into fall. The plant is winding down its own growth cycle.

A fall cutback of the browned stems keeps a front bed looking neat, though the plant does fine either way.

Winter

Winter is fully dormant, with bare ground where the plant was until it resprouts.

• The plant loses its foliage and rests at the crown through winter, so an empty-looking spot in the bed is normal, not a dead plant.
• No watering is needed for an established plant in winter. Typical Dallas winter rainfall covers it.
• Cold weather isn't a concern. This species' native range runs north through Oklahoma, Kansas, and into Canada, so Dallas winters are mild for it by comparison.
• Look for new growth and the first flower buds to reappear in late winter, sometimes as early as February, ahead of most other native plants in the bed.

The bare winter gap can stand out in a front bed, so a nearby mulch layer or winter companion plant helps if a tidy look matters.

Spring

Spring is the standout season for this plant, with blooms opening earlier than almost anything else in a Dallas native bed.

• In the Dallas area, flowering can start as early as late February and run through mid-April, well ahead of most other spring wildflowers.
• No fertilizer needed. As a legume, it fixes its own nitrogen in the soil, so feeding it tends to produce weak, floppy growth instead of better blooms.
• Only water during an unusually dry spring stretch. Normal Dallas spring rainfall is enough for an established plant.
• Watch for the seed pods to form after bloom. They start out green and plum-shaped, which is where the plant gets its common name.

Summer

Summer is a quiet rest period after an early bloom, and the plant mostly takes care of itself.

• Once Dallas's summer heat sets in, expect the foliage to look tired or die back some. That's the plant going dormant for the season, not a problem to fix.
• Skip extra watering unless summer turns into a long drought. In heavy Blackland clay, too much summer water is more likely to rot the roots than help the plant.
• There's no pruning or deadheading task in summer since flowering and pod-set already happened back in spring.
• If you want to collect seed for more plants, gather the pods once they've turned dusty purple and slightly soft, ideally before local ground squirrels and mice find them.
