Hydrangea petiolaris / Tsuruajisai ツルアジサイ


Hydrangea petiolaris, a deciduous liana that emerges aerial roots from trunks or branches and climbs the other bodies to reach 10-20m, grows in mountainous regions. Leaves with opposite phyllotaxis are variable in size and shape, as are on-branch leaves on trees. 5-12cm long, almost oval-shaped, while those on rocks or crawling in the forests are circular, some not to reach 2cm long; those leaves with pointed tips, bases circular with shallow heart-shaped, and more than 30 uneven serrations on one side margins. Branch tips bear 10-18cm-in-diameter inflorescences; ornamental flowers are white, and 3-7 encircle bisexual flowers. Bloom time: June-July.
