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. |
