While the number of new types of bedding plants is vast, the selection and number
of seasonal indoor plants offered for the Christmas season has been relatively small
in Europe. The market still has potential for new material and is largely dominated
by the red and white colours of the poinsettias, hippeastrums and hellebores.
In Europe the introduction of new permanent indoor plants and plantings has
also been limited. However, some very successful examples can be cited. These
include the new spiral form of
Dracaena sanderiana
, and
Zamioculcas zamiifolia,
a tropical plant from Africa, that was introduced from Dutch nurseries in the mid-
1990s and has exhibited good tolerance to drought and low light, and is relatively
resistant to a range of pests and pathogens. Although their flowers last for more than
a week the flower is insignificant. These plants in the first decade of the new millen-
nium have emerged as important pot plants.
