(Origanum species)There are many different species of marjoram and
oregano, but any with a strong scent or flavour can
be used in cooking and to repel insects.
Oregano tends to be tougher and more drought
resilient than marjoram. They all need a well-drained,
humus-rich soil and an open, sunny position. Cut back in
autumn and in very cold regions protect from frost.
If planted near brassicas, marjoram and oregano
confuse the white cabbage butterfly. A hedge growing
around an onion patch protects from onion maggot.
Both marjoram and oregano are believed to increase
the perfume of nearby plants and will generally protect
the other plants.DOG BANE (Plectranthus ornatus)
Dog bane is a perennial, sprawling, succulent
plant to about 40cm when in flower. Leaves are
thick, rounded and pale-green with small hairs. Pale
mauve-blue flowers appear from late summer to
winter in showy flower spikes. Plants need a sunny
position and protection from severe frosts in winter
but they will survive dry summers and can manage
with very little water.
The pungent leaves of dog bane repel a range of
pests and will protect nearby plants from attack. Grow
it as a border to keep dogs away, or break off pieces
and place them in areas where dogs aren’t wanted.
Dog bane doesn’t work on all dogs all of the timePHOTOS: ALAMY but certainly my dog wouldn’t go near it.
