(0)
$4.49
Unit price / perNative to Mexico and Central America, the Mexican tithonia ( Tithonia rotundifolia ) evokes the warm, sun-drenched landscapes from which it originates. In a harmonious garden, its tall, upright stems are crowned with simple, bright orange flowers reminiscent of small wild sunflowers. Planted in welcoming, well-drained soil, it quickly forms a generous clump that adds height and movement to the garden.
Throughout the summer, the plant displays a continuous bloom that attracts numerous bees, butterflies, and other winged visitors. In the privacy of the garden, its benevolent presence structures the flowerbeds while nourishing life. It is a reliable companion for those who wish to invite biodiversity into the vegetable garden as well as the ornamental garden, in a deeply rooted approach to cultivation that respects all living things.

- Growing climate: Warm season
- Sowing difficulty level: Easy
- Care required: Regular
- Growth: Summer growth
Note: Prefers warmth and well-drained soil; dislikes frost and excessive moisture in cold weather.
The Mexican tithonia is primarily cultivated as an ornamental plant. Its large, bright orange flowers add a warm touch to flowerbeds, borders, and naturalistic gardens. It is frequently used as a cut flower in rustic bouquets, where its intense color complements green foliage and yellow or purple blooms.
Some horticultural practices also use it at the edges of vegetable gardens to attract pollinators and beneficial insects near fruiting vegetables (tomatoes, squash, cucumbers, etc.), thus reinforcing the nourishing role of the garden without any particular use in cooking.
