Conservatory Group
With the new additions to the breeding stock, red, orange and pink cannas were developed for the Conservatory along with the original white and yellow. The selection criteria used were plant vigor, early flowering, foliar appearance, self-cleaning ability and good propagation qualities. Between 1972 and 1985, twelve cultivars were selected for release. Named for local historically significant places and events, they were:
- Canna ‘Brandywine’
- Canna ‘Chesapeake’
- Canna ‘Conestoga’
- Canna ‘Constitution’
- Canna ‘Declaration’
- Canna ‘Delaware’
- Canna ‘Franklin’
- Canna ‘Freedom’
- Canna ‘Independence’
- Canna ‘Liberty’
- Canna ‘Lenape’
- Canna ‘Penn’.

Famous quotes containing the word group:
“Once it was a boat, quite wooden
and with no business, no salt water under it
and in need of some paint. It was no more
than a group of boards. But you hoisted her, rigged her.
She’s been elected.”
—Anne Sexton (1928–1974)
