Canna 'Rigoletto'
Introduced by Howard & Smith Nursery, USA in 1930's, Canna 'Rigoletto' is a medium sized Italian Group cultivar; green foliage, oval shaped, spreading habit; oval main stems, coloured green; flowers are cupped, self-coloured yellow, throat some soft-pink mottling, staminodes are large, edges ruffled, stamen is yellow, petals yellow, fully self-cleaning, blooms open in the early morning; fertile both ways, not self-pollinating or true to type; rhizomes are thick, up to 3 cm in diameter, coloured white; tillering is prolific.
Canna 'Rigoletto' is available from specialist growers. It was pretty much agreed by those of us who researched this plant that Rigoletto was just a synonym of Canna 'Burbank', which had become difficult to sell as Luther Burbank went out of fashion with the US public. This cultivar was parcelled up by Howard and Smith, large postal retailers, as a member of the Grand Opera Series, and all the other members of that series were also synonyms of existing cultivars. So, it was agreed that the Grand Opera Series had been a selling exercise, and not a plant breeding introduction of new varieties. There is no evidence that Howard and Smith ever bred any new canna varieties, and that they were plant retailers and not growers.

Hi Malcolm,this looks suspiciously like Canna 'Burbank', which disappeared from US catalogues prior to 'Rigoletto' making a miraculous appearance. I believe this is yet another older Canna that became a victim of marketing hype and was renamed.As far as I can determine, (using the criteria that they appear all-yellow from a distance and are free of largish solid, patches of red overlay); there have only ever been three yellow Italian-type cannas raised: 'Austria', 'Asia'. and 'Burbank'. All three have varying degrees and shades of reddish markings on the base of the main staminodes. The first two are very similar but their foliage differs in that 'Asia' grows with a more relaxed habit and lacks the tight, upright, slightly lanceolate foliage of 'Austria'. The bright lettuce green colour of 'Austria's' foliage is also distinctive. The US raised 'Burbank' is in a class of it's own. The flower heads are not as crowded and being better spaced, the blooms do not look at the sky as is the case with 'Austria' and to a lesser extent 'Asia', but look at the gardener. They are beautifully poised and last longer than those of the two raised in Italy. The foliage on 'Burbank' is broader than that of either 'Austria' or Asia' although 'Asia's' foliage is similarly coloured (mid-green)and poised to 'Burbank's' but not as opulent, being a bit smaller in leaf length and width.I have been looking in vain for some really good photographs of the so-called 'Rigoletto' growing in optimum conditions so that I could make a definitive judgement on the ID. To date I have not found any. It would be nice to see the habit of growth at mid-season.Dale Leave a comment
