Size does matter

A study was conducted to investigate the effects of bulb size (10, 15, 20, 25 cm) on growth and yield characteristics of edible canna (Canna edulis) in Jeju region, Korea Republic, from 20 May to 24 Nov. 2003.

Plant height increased from 78.8 to 129.1 cm as bulb size increased from 10 to 25 cm. Leaf length, leaf width, number of leaves, tillers and bulb per plant and stem diameter followed the same trend as plant height response. Fresh matter yield increased from 29.0 to 91.1 MT/ha as bulb size increased from 10 to 25 cm. Fresh weight of above-ground organs and bulb yield showed the same trend as fresh matter yield.

Comment: So, there we have. That big juicy rhizome we instinctively reach for is going to produce a larger, stronger growing plant than the left-overs, often used as the seed rhizomes for the next year.
