Lupine 'Chateline'

Chateline (Lupinus polyphyllus)

A star of the famed ‘Band of Nobles’ series, Chatelaine Lupine brings timeless romance to the garden with its elegant bi-colour blooms in rose-pink and soft white. Rising on tall, upright spires above a base of lush, deeply cut foliage, these sweetly scented flowers add height, texture, and structure to mixed beds, borders, and cottage gardens. The sturdy stems are excellent for cutting, making ‘Chatelaine’ just as beautiful in a vase as it is in the landscape.

This hardy perennial blooms reliably in its first year when sown early, then returns with even greater abundance in following seasons. A favourite in cooler climates, it thrives in full sun with well-drained soil and is especially striking when planted in groups or drifts. To encourage germination, soak seeds overnight or lightly scarify before sowing.

HOW TO GROW:
Transplant (recommended): Lupines have a long taproot and dislike being moved, so transplanting can be tricky. To increase success, start seeds in deep pots (like tree pots) or biodegradable pots 4–6 weeks before your average last frost. Before sowing, you can scarify the hard seed coat with a file or soak the seeds in warm water for 24 hours to improve germination. Plant seeds ¼–½" deep. Harden off seedlings by gradually exposing them to outdoor conditions before planting out after the risk of frost has passed.

Direct Sowing (alternative): Direct sowing is the best method to avoid transplant shock. Sow seeds in the fall in mild climates, or in early spring as soon as the soil can be worked. Prepare the seedbed well and keep the soil consistently moist until seedlings are established.

Pinching: Pinching is not necessary for lupines. However, deadheading spent flower spikes will encourage a second, smaller flush of blooms.

Soil Preference and Watering: Lupines thrive in full sun and prefer well-drained, slightly acidic to neutral soil. As members of the legume family, they fix their own nitrogen and will not perform well in overly rich soil. Water consistently during germination and establishment. Once mature, they are very drought-tolerant.

Fertilizing: Fertilizing is not required. As nitrogen-fixers, lupines can become leggy and produce fewer flowers if given too much fertilizer.

Harvesting: For bouquets, harvest stems when the flowers are 75% open, and the rest of the  buds are showing color. Cut in the early morning or late evening and immediately place in a vase of water.
