Plants that grow in shade
tend to be vigorous growing ones that are slowed down by the
lack of light but can still manage some growth.
Slow growing plants, on the other hand, grind to a halt and
will probably go backwards and may die.
Don't expect good colour in shady places. Flowers require
a lot of sunlight to develop and variegated plants will often
revert back to the plain green.
Bulbs can do well in shady places, particularly in their first
season, as they live off the food stored in the bulb and don't
require light to the same extent.
However, after flowering, the lack of light means that the
bulb may not be "re-filled" and so may not do as
well in the following years.
Planted Tubs are usefull for shady places as they can be moved
Rotate your planted tubs so that none of them spends too much
time in the shady area and what time it does spend in a shady
area is made up for by time spent in a sunny area.
