Just saw this ,,,
I came across some canna seeds that I had collected in San Raphael, CA when i was living there .. 30 years ago .. the plants grew about 7' tall and hand hanging clusters of pink flowers, they were growing under the 101 overpass and each year the city would mow them to the grown
** about 2 weeks ago , mid September 2021 , I soaked the seeds in rainwater for almost 2 days ( forgot about them ) and planted them in 4' pots and put them outdoors in the sun. full, hot sun .
all but 4 seeds sprouted ,,,
A few sprouted in just over a week, this is how they look now about 2 weeks or so into it .
I am in Sarasota FL
