June to July
Peltoboykinia is primarily grown as a foliage plant. It blends well with ferns, smaller hosta, hellebores and bergenia. This species prefers organic-rich, evenly moist but well-drained conditions in part to full shade. Once established, it is reasonably drought-tolerant, heat-tolerant and humidity-tolerant. Hardy in zones 5-8. It is not fussy in regards to the soil pH.
Larger clumps may be dug and divided in spring. Seeds require a stratification period but even then, may take up to two years to germinate.
