Little Hogweed (Portulaca oleracea) care guide

Little Hogweed is the annual succulent commonly known as purslane, with fleshy leaves, reddish stems, low spreading growth, and small yellow flowers. It is often grown as an edible plant but also appears as a common garden weed.

Yes, Little Hogweed is very easy to grow because it tolerates heat, drought, poor soil, and compacted ground. Its main management challenge is preventing it from spreading by seed.

Little Hogweed grows best in full sun, meaning at least 6 hours of direct sunlight daily, but it can tolerate light shade. Plants may become less compact and flower less in lower light.

Little Hogweed can survive in light shade, but full sun produces stronger, more compact growth and better flowering. Deep shade usually results in weak, stretched plants.

Little Hogweed grows in well-drained sandy, loamy, rocky, or even compacted soil. Avoid constantly wet soil, which can cause stem and root rot.

Yes, Little Hogweed grows well in containers with drainage holes and a fast-draining potting mix. Choose a container at least 6 inches wide for one plant and avoid letting water collect in a saucer.

Yes, Little Hogweed is highly drought tolerant because its fleshy leaves and stems store water. Water it during prolonged dry periods, especially while seedlings are becoming established.

Little Hogweed can grow during the warm season across much of the United States, but it is generally treated as a frost-sensitive annual. In USDA Zones 10 and 11 it may persist longer or behave as a short-lived perennial in suitable conditions.

Water Little Hogweed only when the soil has dried, then water thoroughly and allow excess moisture to drain. Established plants usually need supplemental water only during extended hot, dry weather.

Yellow leaves on Little Hogweed most often indicate excessive moisture, poor drainage, or insufficient light. Let the soil dry between waterings and move container plants to a brighter, better-drained location.

Little Hogweed may wilt from severe drought, root damage, or waterlogged soil. Check the soil before watering, because adding water to already soggy soil can worsen root or stem rot.

Little Hogweed usually needs little or no fertilizer when grown in ordinary soil. Excess fertilizer can produce softer, more sprawling growth without improving its drought tolerance.

Hand-pull or hoe Little Hogweed before it flowers and produces seed, removing as much of the root and stem base as possible. A roughly 3-inch layer of mulch can reduce new seedlings, but disturbed soil may still expose existing seed.

Yes, detached stems can sometimes root again when left on moist soil, especially in warm conditions. Remove pulled plants from garden beds rather than leaving them on the ground.

Sow Little Hogweed seeds outdoors after the soil has warmed in late spring, since germination is favored by warm soil. In many U.S. areas, this is after the last spring frost when soil temperatures are around 60°F or warmer.

Scatter the tiny seeds on the soil surface and press them in lightly without covering them deeply, because light can aid germination. Keep the surface lightly moist until seedlings appear, then thin crowded plants.

Space Little Hogweed plants about 12 inches apart where you want individual plants to spread naturally. Allow more room if you want a broad groundcover effect, but tighter spacing may increase moisture-related problems.

Little Hogweed can tolerate clay soil, including compacted ground, provided water does not remain stagnant around its roots. Improve drainage with a raised planting area or a container if the clay stays wet.

Little Hogweed is propagated most reliably from seed, which it produces abundantly in small capsules. Stem pieces may also root in warm conditions, although seed propagation is the standard approach.

Yes, place healthy stem cuttings on or just in well-drained, lightly moist soil and keep them warm and bright. Allow the cut surface to dry briefly before planting to reduce the risk of rot.

Yes, Little Hogweed readily self-seeds, and its small capsules release numerous black seeds as they mature. Remove plants before seed production if you do not want recurring volunteers.

Routine pruning is not necessary, but trimming long stems can keep Little Hogweed compact and provide edible or propagation cuttings. Remove flowers or seed capsules if you want to limit reseeding.

Little Hogweed is traditionally eaten as a vegetable, but it contains oxalates and should not be consumed in large amounts. Correct identification is essential, and people prone to kidney stones or with kidney disease should seek medical advice before eating it.

Yes, Little Hogweed is considered toxic to dogs and cats because it contains soluble calcium oxalates. Keep pets from eating substantial amounts and contact a veterinarian promptly if ingestion causes drooling, vomiting, weakness, or other concerning symptoms.

Little Hogweed can be toxic to horses because of its soluble calcium oxalates. Prevent horses from consuming large quantities and contact a veterinarian if exposure is suspected.

People who form calcium-oxalate kidney stones should be cautious with Little Hogweed and discuss it with a healthcare professional before eating it. Its oxalate content can be high, and heavy consumption has been associated with kidney injury in rare reports.

No, Little Hogweed is Portulaca oleracea, while moss rose usually refers to Portulaca grandiflora or related ornamental portulacas. Do not assume an ornamental portulaca is edible simply because it resembles purslane.

Little Hogweed usually blooms during the warm growing season, beginning several weeks after germination and continuing until fall frost. Its small yellow flowers often open in bright sunlight and may close later in the day.

Little Hogweed flowers are typically yellow and have five small petals. They are relatively inconspicuous compared with the large, brightly colored flowers of ornamental moss rose.

Insufficient sunlight, cool weather, excessive fertilizer, or severe stress can reduce flowering. Move container plants into full sun and avoid keeping the soil constantly wet.

Little Hogweed can flower within several weeks of germination and produce mature seeds soon afterward during warm weather. Regularly remove flowers or seed capsules if you want to prevent it from spreading.
