Nipponanthemum nipponicum (Nippon Daisy, also called Montauk Daisy) is a late-season perennial that brings clean white daisy flowers when many gardens are winding down. You get an upright, bushy clump with thick, glossy green leaves and a long stem display of fresh-cut blooms in early fall.
Plant it where it can dry out between waterings. It performs best in full sun, but you can also grow it in light part shade, especially in hot climates. Aim for well-drained soil; once established it handles dry conditions well and is a good fit for coastal plantings where some salt exposure is possible.
At maturity, expect about 24-36 inches tall with a broad footprint that can reach roughly 36-60 inches wide. The lower stems can become sparse as the season progresses, so you may want to place shorter perennials in front to soften the base and highlight the flower stalks.
For easy care, cut back or pinch new growth in spring to encourage a denser, more compact shape. Deadhead to keep the plant tidy and encourage continued blooming. If the clump becomes crowded, divide it every 2-3 years. The flowers are also a nice butterfly draw and hold well in a vase.
