Bonehead said:So, what web site is best to use for reliably accurate information?
Since there is no single source for reliable information it's necessary to approach cultivars differently than species plants. There are international cultivar registration authorities (ICRA) for some but not all genera. ICRA maintain registries of cultivar names but not all are online or viewable without joining a society. Two good general websites to visit are the Missouri Botanical Garden and the Royal Horticultural Society databases. The RHS is the ICRA for quite a few genera. Here are some bullet points which might help.
International Society for Horticultural Science list of
ICRA, alphabetical by genus. A website to a society is often shown.
A few general go to sites:
Missouri Botanical Garden ,
Royal Horticultural Society,
KAVB (for bulbs).
A few ICRA and good helpful sites (mostly to illustrate how you may need to search):
ICRA for Hosta -
American Hosta Society registry
Helpful site -
Hosta Library
ICRA for conifers -
RHS Conifer register
Helpful site -
RHS Encyclopedia of Conifers,
American Conifer Society ConiferBase,
