Care Guide
Planting
Plant your silver lupine in full sun in well-drained, sandy soil - nutrient-poor soil is actually what this plant prefers, so skip the compost. The plant tolerates a variety of soil types as long as drainage is fast; if your garden tends to stay wet, amend with sand or gravel before planting. Space according to the plant's mature size of 3–5 feet tall and wide.
After Planting
Water weekly for the first summer to establish the plant, then cut back to a maximum of twice monthly once established - this is a drought-tolerant plant that struggles with too much water. Expect this shrub to be somewhat short-lived, but it will thrive in the right dry conditions; your main mistake will be overwatering, which can kill it quickly. The plant is evergreen and deer resistant, requiring minimal fuss once established.
