The aim of
this site is to provide information about the genus that will be of interest to
both gardeners and Crocus aficionados.
The core of the site is a large collection of digital images of Crocus
plants, which will serve to illustrate botanical details and the variation
exhibited by the species. This in turn
may assist in identification of plants.
The image
content of this website is built around a collection of Crocus plants grown by
Tony Goode who gardens in Norwich UK.
The plants are part of the NCCPG National Collections
Scheme, which promotes the conservation of plants in cultivation. Several resources have been referred to in
literature, most notably Brian Mathews’ revision of the genus: ‘The Crocus’
(Batsford 1982 ISBN 0 7134 3390 6) now out of print but obtainable through
specialist second hand book dealers.
Other excellent reference works are listed below.

The genus
is mostly known for the Dutch hybrids and ‘Species’ crocus both of which make
good garden plants flowering in the spring.
The genus is much more variable than these plants would suggest. There are 79 species further divided into
127 taxa when subspecies are included.
The flowering season extends from late summer (August in UK) through the
winter until mid spring (March UK.)
(Seasons vary from year to year and with latitude so these are only
local guidelines.)
All the
images on this site are Copyright Tony Goode.
If you would like to use them for any purpose, please contact me. (I have the original images which are larger
files which show greater detail.)
The
navigation has been designed to allow users to move around the site to explore the
plants with links on each page to help you move between related species, while
also being able to research botanical details if new or unfamiliar terms are
encountered. The navigation will become
more sophisticated as the site develops to its full potential over the coming
months

I grow most
of my crocuses in plastic pots, which are sited in cold frames. The cold frames have open sides throughout
the year and glass covers, which are used for winter protection and to ensure a
dry summer rest (for those species which need it). The compost used is roughly 50% John Innes II (a loam based
commercially mixed compost), 40% coarse, sharp sand, (very gritty sand up to
5mm), 10% perlite, (improves aeration of the compost and holds water.) A small measure of bonemeal is added (high
in potassium which feeds growing corms).
Plastic
pots are used for their space efficiency, more can be fitted into each frame
than the round clay pots which I have used in the past. Clay pots are aesthetically more pleasing.
A more generous
watering regime is required with clay pots as the compost dries out more
quickly than in plastic pots. A careful
watch is kept for aphids which are afforded some protection by the dense
foliage that develops after flowering.
Systemic and contact insecticides are used when required.

this is not the most sophisticated web site tool. Suggestions for improvements are welcomed.)
