Description – Canna Alaska

Canna Alaska is a medium sized Crozy Group cultivar, with white flowers and green foliage.
Participated in the 2002 Canna Trials conducted by the Royal Horticultural Society in their gardens at Wisley.
Deemed to be the best white in the Trials, even though it was exactly like C. ‘Chesapeake’ which was growing alongside it.
Entered in the trials by Agrexco, it is reputed to be an unnamed seedling from Rev. Curtis Wallace’s intensive breeding programme.

Synonyms

None known to us, please advise if synonyms are known to you.

Foliage

The average sized green foliage has oval-acuminate shaped leaves with a white margin.

Stems

The oval main stalks are coloured green, branching into triangular flower stems which are also coloured green.

Flowers

Spikes of flowers are open, self-coloured white and the throat is lemon.
The staminodes are medium size and the edges are lightly frilled, with the stamen coloured cream, and the style being cream.
The sepals are coloured yellow, and the flowers are fully self-cleaning.
The plant outstanding bloomer, with the blooms opening in the early morning.

Fertility

Seeds are fertile, contained in round seed pods (capsules).
The pollen is fertile, but the flower is not self-pollinating.
The anther is positioned low on the stamen and when the flower opens the pollen is excreted onto the style, but misses the stigma, meaning that it is not self-pollinating and a pollinator is required to transfer the pollen to the stigma and so fertilise the seeds.
Suitable pollinators are bees, hummingbirds, moths, some insects and even some small types of bats.
The seedlings resulting from a self-pollination, or fertilisation with pollen from another plant of the same type, are not true to type even if they look identical to the parent(s).
The seedlings should never be given the same name as their parent(s), as there are genetic variations which make them different.

Rhizomes

Rhizomes are thick, up to 3 cm in diameter and coloured white.
Tillering is prolific.

Introducer

Introduced by Rev. Curt Wallace.
