Constance  is a decorative rose which makes a dazzling display in the garden as the full blown blooms hold well on bush without discolouring. The colour is darker than 'Super Star' but the blooms have fewer petals.

p165. Mr. W. G. Treloar of Portland, Victoria.  The New Ones.  
Constance  is an ideal bedding rose because of its vivid vermiIion blooms which are produced very freely.

Constanza (Tantau) A clear bright vermilion Hybrid Tea with a good bud and an open flower of 25 petals. The open bloom is most decorative, and also holds well. The foliage is good and the plant is free flowering. A very good variety.

Constanza, HT. (Tantau, 1966) Darker than 'Super Star' but with less petals - only 25 to 30. Good in form, freedom of bloom, foliage and growth.
