B. Joe has the most beautiful Canna's I have ever seen and certainly would love to know who your supplier is. TIA
The supplier is irrelevant, as long as the rhizomes are healthy. I get them from trades, EBAY, Karchesky Canna, local nurseries.
My secret is TONS of water and fert, and believe it or not, about 95% of those in the photos are grown in pots!
Give them lots of sun, heat and humidity, tons of water and fert and you can have the same.
