A quiet, wise man
EVERY year, thousands of visitors to the Lady Norwood Begonia House at Wellington Botanic Gardens went home
wiser and keener gardeners thanks to the quiet man who chatted to them as they moved among the brilliant displays.
Mike Wilton, who supervised the Begonia House, died on July 29, leaving an immeasurable gap in Wellington's horticultural
knowledge banks. He was not only widely read and highly qualified, but was a wise and skilled plainsman. Over the
years, he shared his knowledge many times with Dominion Post garden readers, from mucking out the lily pond to
the finer points of raising streptocarpus.
A descendant of the Wilton family after whom the Wellington suburb of Wilton and the renowned Otari Wilton's Bush
are named, Mike was a former dux of Horowhenua College and held a degree in biochemistry He never relinquished
his thirst for learning: his wide interests included space travel and volcanoes. He had his own website and designed
the Begonia House's first website.
Early on, Mike started his own nursery and specialised in potted colour before it became the fashion. But though
he lavished care on all his plant charges, orchids and begonias were his foremost interests. He was a national
orchid judge and a popular guest speaker.
When we last talked, Mike was raising more than 2000 begonia seedlings at home and several of his finest were on
display in the Begonia House, including a spectacular picotee double, which he said he'd grow on for another year
to "see if it was good enough". Perfection was ever his aim and more often that not, his achievement.
Mike died suddenly while working on a re-vegetation scheme at Maupia on land once held by the iwi from which he

Lady Norwood Begonia House in Wellington Botanic Garden has a wide
range of plants including, Begonias, Orchids, Bromeliads, Cyclamen, Primula, Impatiens, foliage plants,
and a variety of bulbs in permanent plantings and seasonal displays. Victoria amazonica and V. cruziana
can be found in the Tropical Waterlily Pond along with Nelumbo nucifera, the Sacred Lotus. Integrated pest
management, including Biological control is used for pest control.
The Begonia House and its extensions form the backdrop to the Lady Norwood Rose Garden, and were built with
the help of substantial funding donations from Sir Charles Norwood, and the Norwood family.
Sir Charles and Lady Norwood were a former Mayor and Mayoress of Wellington. They were enthusiastic advocates of
the city parks and gardens, and particularly the Rose Garden area of the Botanic Garden.
The house was built in 1961 without the present Cafe or Lily pond areas. The Cafe was added in 1980. The Tropical
Waterlily Pond was added in 1989, while the rest of the house underwent extensive renovations, which were completed
The Begonia House is more correctly a conservatory because a wide range of tropical and temperate plants are grown
and displayed all year round in the house, however during the summer months the spectacular Tuberous Begonias
are the dominant display plants and it is from these displays that the house gets its name. Recent efforts have
been made to extend the Begonia collection into a wider range of different types.
The house is divided into 2 sections.
Seasonal displays of potted flowering and foliage plants make up the main displays
in this section. there are also 2 beds of permanent and semi permanent plantings of larger growing plants, including
the spectacular huge leafed Damaropsis kingiana. (syn. Ficus kingiana.)
Tuberous begonias in summer
This section is heated to a minimum of 15oC.
Main display plants and collections;
- Tuberous Begonias, both pot and basket types, with their spectacular large colourful flowers, play the
starring role, and dominate the displays during the summer months.
- Begonias such as cane, rhizomatous, and non tuberous basket types are also grown and many of these flower
at other times of the year, particularly winter and spring.
- Streptocarpus or Cape Primrose hybrids also feature during the warmer months of the year.
|Cyclamen and foliage in winter
- Cyclamen and Primula obconica provide the main floral display during winter.

- Aquatic plants in the Tropical Waterlily Pond.
The Tropical Waterlily Pond is housed in an extension to
the Tropical section, and was opened in November 1989. It was built to grow the giant Amazon waterlily species
Victoria amazonica and V. cruziana. The pond is heated to between 23o and 27oC
depending on time of year, and is stocked with tropical fish, mainly Guppies and Swordtails, to keep algae down.
Goldfish in the pond have been dumped there by members of the public! Unfortunately they eat the beneficial tropical
Apart from the Victorias, the pond also home to a white form of the Sacred Lotus, Nelumbo nucifera
and several tropical and hardy waterlilies of the genus Nymphaea.
Integrated Pest Management.
High toxicity pesticides such as organo-phosphates have not been used for general pest control in the Lady Norwood
Begonia House since 1993.
Pest control is now based on Integrated Pest Management. This involves monitoring pest
population levels and where necessary, reducing the populations using physical and environmental means, Biological
control, or low toxicity chemical or biochemical means.
Biological control methods are used for the pests; Two-spotted mite, White fly, and Mealy bug.
