Common Name Spotty Dotty Mayapple, Asian Mayapple
Genus  Podophyllum
Species Hybrid (derived from Asian Podophyllum species)
Family Berberidaceae
Life Cycle  Herbaceous Perennial
Format 36-cell half tray 
Plug Care Harden off and plant plugs promptly upon arrival. Keep the root medium evenly moist but not fully saturated. Monitor moisture carefully while in the trays but also post-transplant while roots establish. Plant at the same level as the plugs were growing in the trays - do not plant deeply.  Do not allow young plants to dry out fully - they like moist woodland conditions. 
Netting / Staking Not necessary - the foliage and stems stand naturally; no special support needed.
Temperature Range Hardy in USDA Zones 6 to 9
Spacing Space plants approximately 18 to 24 inches apart as they will spread over time. 
Soil Preference Prefers humus-rich, organic, deep, moist but well-drained soils. Avoid heavy, waterlogged clay soils or any site that is dry. Neutral to slightly acidic soils are best - you can fertilize to speed growth, but avoid fertilizers heavy with nitrogen as this minimizes patterning on leaves and can cause soft growth. The addition of lots of organics such as compost at the time of planting will make the soil more humusy. The use of a thin layer of leaf mulch on the soil surface helps lock in soil moisture. 
Sun Requirement Part shade to full shade (woodland setting) - avoid hot/sunny/windy/exposed conditions. 
Pinching Do not pinch. 
When to Plant Plant late spring and early summer, well after the threat of frost has passed - frost will damage tender new growth. Water regularly during establishment to prevent the plants entering dormancy.
Harvesting This is meant to be grown as an ornamental plant in the shade garden and is not intended for use as a cut flower. 
Post Harvest Care N/A
Diseases / Insects These plants are not prone to any diseases or insect pests. As long as they are planted in the proper conditions, they should thrive. Saturated soils can encourage rot. Make sure to keep any neighboring plants under control to prevent unnecessary competition. 
Bailey's Notes In many climates, ‘Spotty Dotty’ keeps foliage through much of the growing season and does not necessarily go fully dormant during summer heat unlike some Mayapple relatives. In very hot conditions or during periods of drought stress, foliage may decline or appear semi-dormant. ‘Spotty Dotty’ is rhizomatous and will slowly form a colony. Spread is slower than some native mayapples. In regions with harsher winters, provide winter mulch or leaf litter cover to moderate soil freeze/thaw cycles. Protect new growth from late spring frosts.
