Wiliwili seedlings from the Lyon Arboretum are repotted and sprouting leaves.
They will grow in pots until 2010 and then be planted in the Arboretum expansion project when the whole 17 acres of Pu’u Mahoe will be deer fenced with a USDA grant.
Merit Granules has worked successfully on potted and young out-planted Wiliwili.
They will be cared for gall wasp free. There will be a few extra seedlings to distribute if you would like to suggest other recipients. I imagine Wiliwili seedlings will be in demand once biological control is effective.
We are honored to receive seedlings from the Lyon Arboretum seed storage experiments of Maui’s rare dry land plants, as a Dry land Plant Recovery Reserve for Maui.
