Jeffersonia diphylla
Jeffersonia are small, clump-forming perennials, native to North America. They have 2-lobed, kidney-shaped leaves and, in Spring, bowl-shaped white or lavender blue flowers Jeffersonia diphylla - Blue Twinleaf - is a woodland plant that is a clump-forming deciduous perennial that bears 2.5 cm. 8-petalled, pure white flowers that open in early Spring at the same time as the new leaves
Flowering
From Early Spring TO Mid Spring
The bowl-shaped flowers appear in Spring, at the same time as the leaves. Plants usually flower in the second or third year of growth
Planting
From Early Spring TO Late Spring
This is a woodland plant, and so needs woodland conditions of shade and damp need to be grown successfully. Plant in preferably alkaline, moist but free-draining soil, in full or partial shade.
Propagating by seed
From Early Spring TO Mid Spring
Sow seeds in a pot or tray filled with proprietary seed-sowing compost, or a 50/50 mix of multi-purpose compost and perlite or coarse grit. Sow large seeds with space between the seeds, and sow small seeds thinly, and cover the seeds with a thin layer of sieved compost (unless it is a type of seed that needs light to germinate). Water gently with a fine rose on the watering-can, allowing excess water to drain away.
