Zinnia haageana, commonly known as busksinnia, is a low-growing annual plant valued for its small, double or semi-double flowers in vibrant shades of yellow, orange, and red. Its petals often feature contrasting tips, creating a very attractive bicolored effect. It is ideal for garden borders, pots, and as a cut flower in small arrangements, adding continuous color throughout the summer.

Care tips
It requires full sun for abundant flowering and optimal development; at least 6 hours of direct sunlight per day. Watering should be regular, keeping the substrate moist but not waterlogged, especially during dry periods. It prefers well-drained soil, rich in organic matter, and with a slightly acidic to neutral pH. Avoid overwatering and waterlogging, as this can lead to fungal diseases and root rot.
