Hymenocallis maximiliani (Large bulb) is a close cousin to our beloved 'Tropical Giant' and a wonderful choice if you want that same bold, tropical look with a little more polish. It grows about 3 feet tall in a 3-foot clump of leaves, but the foliage is narrower and glossier, catching the summer light along a border or by the porch steps. Like all of our spider lilies, it shrugs off Southern heat and humidity and asks very little of you once it settles in.
Blooms: The slender, elegant white petals unfold from a delicate cup in the center of each flower, giving the 7-inch blooms that classic "spider" look. The blooms open periodically in the evenings during May, June, and later into the summer, and they produce a large amount of seed.
Planting: Plant in spring once the soil has warmed, setting the bulb so the tip of its neck is just at or slightly above the soil surface. Choose a spot in full sun to part sun with rich soil; it will tolerate just about any moisture level except drought, and it is happiest with even moisture. Space bulbs about 2-3 feet apart so each one has room to form its 3-foot clump, and water well after planting. It is hardy in roughly zones 7b-10; in the cooler end of that range, mulch over the bulbs in winter.
Landscaping Tip: Use it the way you would 'Tropical Giant' — as a summer accent plant in a mixed border, along a pond or rain garden edge, or in a row along a walk where you can enjoy the evening blooms. It pairs well with heat lovers like lantana, salvia, and esperanza.
