Ipomoea indica
(Burm.) Merr.
Blue Morning Glory, Blue Dawn Flower, Dunny Creeper
Perennial climbing plant, which can grow to over 6 metres in length and
form large masses of several tens of square metres, destroying all the
vegetation in its path.
Its leaves are deep green, heart-shaped, with
three prominent lobes. The funnel-shaped flowers, of a beautiful and
intense purplish blue, purple, red or pink colour, last one day and then
wither.

It is an annual herbaceous plant with long, slender stems up to more
than 10 m long, circular in cross-section, voluble, profusely branched,
with no linear projections or very few marked ones, which entangle
themselves on any support, covering areas of several square metres.
When it climbs on trees or bushes it can kill them, as their dense
foliage deprives them of the essential sunlight needed for
photosynthesis.
Its leaves, of an intense green colour and up to 8 cm long, are simple,
alternate, long stalked and very variable in outline: from heart-shaped
to three-lobed, covered on both sides with a short and slightly rough
hair.
The attractive flowers, which vary in colour from pale pink to
intense violet, develop in small clusters supported by very long stalks.
They have a short hairy calyx and a wide, funnel-shaped corolla with
five clearly visible radial lines, which are slightly different in
colour to the rest of the flower and whose purpose is to guide the
insects which, attracted by its sweet nectar, pollinate this plant.
