FIRST FLUSH™ Lavender Iberis sempervirens

FIRST FLUSH™ Lavender is a mounded *Iberis sempervirens* selection bred for first-year flowering without vernalization. The ThinkPlants catalog links this trade selection to Plant Patent PP34517; the patent record names the cultivar ‘DIBFRFLAL’ and describes light lavender flowers that bloom from spring into summer. ## Form, Flowers, and Size Kew lists *Iberis sempervirens* in the family Brassicaceae. The patent reports plants about 25 cm (10 in.) tall and 30 cm (12 in.) wide. The [Danziger First Flush guide](https://www.danzigeronline.com/wp-content/uploads/2025/01/Iberis-First-Flush-2026.pdf) and [ThinkPlants catalog](https://online.flippingbook.com/view/475159583/66/) give series grower dimensions of 6–8 in. tall and 12–14 in. wide, so published size figures vary with source and production context. ## Site and Season Plant in full sun to part shade. Danziger recommends even soil moisture, good airflow, and avoiding persistently wet conditions. Its guide says a short period of cool temperatures can improve flowering uniformity, while ThinkPlants lists the selection as not requiring vernalization. Hardiness listings also differ: Danziger gives USDA zones 4–9 and ThinkPlants gives zones 5–9. ## Maintenance Keep moisture even without leaving the root zone consistently wet. Pinching at transplant or during production can maintain a compact finished plant; larger containers may need an additional pinch. Monitor for aphids and thrips.
