Bring dramatic early-summer color to your garden with Lupinus polyphyllus 'Westcountry™ Polar Princess'. You will love its tall, clean-white flower spires rising above bold, palmate foliage, adding classic cottage-garden structure and strong vertical interest.
Plant it in full sun to part shade; in hotter climates, a little afternoon shade helps extend performance. Provide well-drained soil and avoid waterlogged sites, especially in winter. Water regularly during establishment, then keep the soil evenly moist through active growth for the best bloom spikes.
This lupine forms a clump and typically reaches 24-36 inches tall, making it a natural fit for mid-border plantings. Because it develops a deep taproot, you will get the best results by choosing its spot carefully and minimizing transplanting once established. A light mulch can help moderate soil temperature while keeping the crown from sitting in soggy conditions.
After flowering, remove spent spikes to keep the plant tidy and encourage continued vigor. Stake in windy areas if needed, and give it room for good air flow. Pair it with other sun to part-shade perennials for layered bloom and a strong seasonal display.
