"meadow-Looking" landscape with sowing seasonal flowers seed mix?

[dkp]

I am in the field of landscape architecture.

In the western countries, there is commericial supply of wild flower seed
mix for project to produce "meadow" habitats.

Is this concept able to be borrowed to suit the Hong Kong context? First of
all, is there an equivalent ecological habitat in Hong Kong? Of course, we
have wild flowers in Hong Kong. But i am sure there is no commercial supply
of them.

Then, i shifted my direction of thinking to seasonal flowers whose seeds are
readily available from commercial source. Traditionally, the use of seasonal
flowers in landscape project is expensive due to the need for frequent
change of blooming seasonal flowers.

I have an idea but i am not sure if it works or not. If i mix the seeds of
both spring sown and autumn sown seasonal flowers, and cast-seed or
hydroseed them, will i be able to obtain a "meadow-looking" landscape?
Assuming the plants produce seeds by themselves and there are seed
dispersals, theoretically, the "meadow-looking" landscape shall be able to
sustain itself.

From the experience of western meadow, i understand the crucial factors for
a well meadow creation are : 1) elimination of weeds and weed seed of the
planting area before sowing of seed mix; 2) planned cutting of the meadow.

If the idea i am thinking works, maybe there is an alternative to produce
colorful landscape that is "meadow looking" and yet economic to set up.

Please give comment on my idea of producing sustaining "meadow-Looking"
landscape with sowing of seeds mix of seasonal flowers? Do you think it is
feasible and what possible issues will be encountered? YOur precious opinion
is appreciated.
