Care Guide

Planting

Plant Sky Lupine in full sun in fall or winter - it's an annual that flowers winter through spring, so timing your planting for the cooler season gives it the best shot. This plant is unfussy about soil and will tolerate sandy or clay soils with fast, medium, or slow drainage, so don't overthink your soil prep. Space them as you'd expect for a dwarf plant (0.3 to 2 feet tall depending on variety), and you can even tuck them into containers if you prefer.

After Planting

Water moderately through the growing season, but once established, you only need to water a maximum of twice a month during summer - this is a drought-tolerant native. The main mistake people make is overwatering; resist the urge to keep it constantly moist. Since it's an annual, plan for it to complete its lifecycle in one season, though it will self-sow if you let seed heads mature, giving you volunteers next year.
