is a notorious 'flopper'. To prevent this and avoid staking, trim back the early spring growth (a). This
provides a stronger framework from which to flower (b). At the end of flowering, prune back the flowering stems to the
ground. Depending on your climate there may or may not be fresh growth at the base of the plant (c). In some areas it
may not emerge until the next growing season.
Tall herbaceous perennials (see Table 4.9)
often need staking - an ugly alternative to
their complete collapse. This can be
prevented. When the plant has gained about
a third of its ultimate height, lightly trim the
new growth to form a strong structure from
which to flower (see Figure 4.28).
Roses
There are few humans that do not respond
positively to the rose. Roses are so revered
that many seem to think that they are
difficult to grow. They require constant
'work' and someone with almost mystical
powers to grow them to perfection. After all,
how can something so beautiful be anything
but difficult to attain? Yet, when it comes
down to it, they are flowering shrubs much
like all the others. In fact, they are usually
hardier and more resilient than many shrubs.

Heliotropearborescens

When the flowering season is over
*
Cut down in the dormant season to a base of sturdy branchlets.

Cut to the ground completely, new growth will come (or has
arrived) from the base.
‡
Evergreen species should retain their leaves over the dormant
season; only the flower stems are removed.
