About
Alstroemeria 'Neptune' is a compact perennial that reaches heights of up to 90 cm. It features lance-shaped, mid-green foliage and produces clusters of funnel-shaped flowers in late summer and autumn. The blooms are predominantly pinkish-purple with creamy-white inner petals, which are prominently marked with purple-brown flecks, while the outer petals display a subtle dappling. This plant forms dense clumps, making it an excellent choice for borders or as a garden accent.
