About Mexican lupine
Lupinus mexicanus, commonly known as tremoço, is an annual or short-lived perennial legume native to Mexico, valued for its showy spikes of blue, purple, or white flowers. It grows 30 to 90 cm tall, and its palmate foliage adds interesting texture to the garden. It is ideal for flower beds, borders, or as part of a pollinator garden, bringing color and attracting bees and butterflies.

Care tips
It requires full sun for abundant flowering and well-drained, slightly acidic to neutral soil, enriched with organic matter. Watering should be regular during its growth and flowering, avoiding waterlogging, and reduced once established. A common mistake is planting it in heavy or clay soils, which can lead to root rot; ensure good drainage. It doesn't need much fertilization, as, being a legume, it fixes its own nitrogen.
