LEARN: Habitat of Hairy Balls Milkweed

Hairy Balls Milkweed (Gomphocarpus physocarpus) is native to Africa and is found growing naturally in various habitats across the continent. It thrives in sunny, warm climates and is adapted to a range of soil conditions, from sandy to loamy, as long as the soil is well-drained.

GROW: Growing Conditions

Growing Zones: Hairy Balls Milkweed is typically grown as an annual or tender perennial in cooler climates (USDA zones 8-11), where it can be treated as an annual. It prefers warmer temperatures and does well in zones where the growing season is long enough to support its growth.

Soil Types: This plant prefers well-drained soil but is adaptable to different soil types, including sandy or loamy soils. It doesn’t do well in heavy clay soils that retain water.

Water Requirements: Hairy Balls Milkweed has moderate water needs. It prefers regular watering to keep the soil evenly moist, especially during dry periods. However, it is important not to overwater as it can be sensitive to waterlogging.

CHANGE: Companion Planting

Companion planting involves choosing plants that benefit each other when grown in close proximity. Here are some considerations for planting Hairy Balls Milkweed with other plants:

1. Butterfly and Pollinator Gardens: Hairy Balls Milkweed is excellent for attracting butterflies, especially monarchs. Planting it alongside other nectar-rich flowers like coneflowers (Echinacea), bee balm (Monarda), and lavender can create a vibrant pollinator garden.

2. Tall Annuals or Perennials: Due to its height (up to 5 feet or more), Hairy Balls Milkweed can be planted alongside tall annuals or perennials like sunflowers (Helianthus), rudbeckias, or tall grasses to create a visually appealing backdrop in the garden.

3. Herbs and Vegetables: In mixed planting beds, consider planting Hairy Balls Milkweed with herbs such as parsley or dill, which attract beneficial insects like ladybugs and predatory wasps that help control garden pests.

4. Contrasting Foliage: Plants with contrasting foliage textures and colors, such as lamb’s ears (Stachys byzantina) or ornamental grasses, can complement the fine, hair-like texture of Hairy Balls Milkweed’s seed pods and leaves.
