I
know it’s painful but we got
to draw the line somewhere. These plants are problems and I’ll tell you
why. There are so many better choices available that I don’t have room
to list them here, but once you can break the habit of using big box stores
as nurseries, you’re well on your way to upgrading and up-greening your
garden. Groundcovers
Carpobrotus
edulis iceplant Yes, it’s everywhere at
Hedera
species ivy Sure, it’s green and quick
spreading and sticks to anything, but it destroys habitat, damages buildings,
chokes trees and destabilizes banks.
Vinca
major periwinkle An easy solution for shady areas, which easily escapes into stream
sides, crowding out native species Perennials
Cortaderia
selloana
pampas grass Pretty fluffy plumes, pretty nasty
invasive, plus the leaves will slice you up. It crushes everything in its
path and is a fire hazard.
Pennisetum
species fountain grass A common staple in Shrubs
Bamboo I can hear
the outcries but believe me, this stuff gets out of hand and is difficult to
remove. I will admit there are bunching bamboo species that are better
behaved, but most of them travel far and wide underground, pushing up other
plants, as well as brick, and widening the slightest crack in cement or
asphalt.
Cotoneaster cotoneaster Its bright red berries turn into little green seedlings that grow
gnarly and pushy root systems and bully other plants wherever they sprout,
including natural areas.
Cytisus
scoparis, Genista monspessulana, Genista hispanica scotch, french and spanish brooms When these invasives
‘sweep’ in, they are extremely hard to extricate. Seeds persist
for many years. A few years ago I saw a pen of goats on
Roses OK,
before you start throwing your clippers at me, let me clarify. Don’t plant the wrong rose for
your garden. Most roses I come across either barely hold on in this climate
(fancy hybrid roses that don’t even smell) or are clawing their way
into every inch of available airspace (Cecil Brunner I am calling you out).
When choosing a rose take into account how much sun and fog you get, how pest
and disease resistant it is, and how much space you are willing to provide.
Also how much stabbing you’re comfortable subjecting your gardener to. Trees
Maytenus
boaria
Maytens tree I admit it’s a lovely tree, with swaying
branches reminiscent of a Vegas showgirl, but its unruly habit of rocketing
up sprouts from its tough orange roots is a deal breaker for me. Installing
this tree is asking for trouble. Vines
Convolvulus morning glory While I can’t quite put into
words my feeling about this plant, this blogger wrote quite
a screed. It chokes everything and harbors whitefly. Instead, try the |
