Pineapple Weed

Pineapple Weed

Matricaria discoidea

Pineapple Weed is an annual herb characterized by its distinctive pineapple-like aroma when crushed. It grows up to 30 cm tall, featuring finely divided, fern-like leaves. Unlike true chamomile, it lacks showy petals, instead producing conical, greenish-yellow flower heads. It thrives in disturbed areas like roadsides and gardens. While sometimes used medicinally and as a flavoring, it's primarily an outdoor plant and doesn't typically thrive indoors due to its high light requirements and weedy nature. People may grow it for its novelty and edible qualities.

❓ Frequently Asked Questions — Comparing These Plants

Butterfly Pea

What are the light requirements for Butterfly Pea?

Butterfly Pea thrives in bright, indirect sunlight. Direct sunlight can scorch the leaves, so it’s best to place it near an east- or west-facing window where it receives gentle morning or afternoon light. If you’re growing it indoors, supplement with a grow light, especially during the winter months when natural light is limited. Insufficient light can lead to leggy growth and reduced flowering.

How do I care for Butterfly Pea?

Butterfly Pea thrives in warm, humid conditions with bright, indirect sunlight. Plant in well-draining soil amended with compost. Water regularly, keeping the soil consistently moist but not waterlogged, especially during the growing season. Fertilize every 2-3 weeks with a balanced liquid fertilizer or a fertilizer higher in phosphorus to promote blooming. Provide a trellis or support structure for the vine to climb.

How do I propagate Butterfly Pea?

Butterfly Pea can be propagated through seeds, stem cuttings, or layering. For stem cuttings, take a 4-6 inch cutting from a healthy stem, remove the lower leaves, and dip the cut end in rooting hormone. Plant the cutting in moist potting mix and keep it in a warm, humid environment until roots develop.

Pineapple Weed

What are the light requirements for Pineapple Weed?

Pineapple Weed thrives in full sun, requiring at least 6 hours of direct sunlight per day. However, it can also tolerate partial shade, especially in hotter climates. Insufficient light can lead to leggy growth and reduced flowering. If growing indoors, place your Pineapple Weed near a south-facing window or under grow lights.

How do I care for Pineapple Weed?

Pineapple Weed is a relatively low-maintenance plant that thrives in well-drained soil and full to partial sunlight. Water regularly, especially during dry periods, but avoid overwatering, which can lead to root rot. Fertilize sparingly, using a balanced fertilizer diluted to half strength, only during the growing season (spring and summer).
