Alstroemeria 'Inticancha Antarctica'
Alstroemeria ‘Inticancha Antarctica’ is a dwarf white selection in the Inticancha series, bred for compact habit and long, profuse flowering. Its standout trait is crisp white blooms marked with burgundy streaks on a tidy, non‑invasive clump. It excels in containers and small beds in warm‑winter regions, and as a summer container plant elsewhere. Plants bloom from early summer well into fall given sun, drainage, and regular moisture.
