Confusion Reigns
There is a fantastic amount of confusion about the various species of delphinium and the origins of today’s hybrids. Please see this article (first page of thesis) by way of explanation.
This confusion is such that delphinium hybrids resembling the Pacific Giant types often referred to as D.culturum (in culture) as the real origins are extremely complex and probably unknown.
To help clear this confusion the following delphinium groups are generally available in commerce:
These plants have complex flowers and range in height from about 2 metres to about 1 metre. and include:
- Various Pacific Giants Series (This includes Round Table, Dwarf Pacific and all the varieties in those series, eg Black Knight, Galahad)
- New Millennium Series
- Magic Fountain Series
- And a host of others
