areas, which combine native and exotic species available
commercially and that minimise the risk posed by
the use of alien plants. To achieve this objective the
manual makes use of 332 indigenous and exotic plants
and offers 40 ready to make garden designs that include
green areas for different types of private residences,
roundabouts, traffic islands, central reservations or maritime
walks, but also small scale garden designs for outdoor
planters and plant pots of different sizes. The book
provides different examples for each of these gardens
suitable for coastal or inland areas and takes into account
the aspect of plantations or the availability of water
resources. Throughout the book, the emphasis is put
on providing alternatives to invasive plants commonly
used in the Valencia region and to make it more explicit
an annex at the end lists major invasives and possible
alternatives depending on uses.
In summary, “Mediterranean gardening without invasive
species” aims to to become a useful tool to
assist in the design of sustainable gardens of all
types both to amateurs, professionals and the different
administrations alike by providing viable proposals
from an environmental and commercial perspective
to combat the serious threat posed by the
use of ornamental plants with invasive potential
