In my neck of the woods, it's rare to see clivia offered locally, but I did find some recently. In fact, I hit the jackpot. Someone on DG mentioned finding some 1 gal. plants at a nursery at a nursery in Columbia, SC for $8. I had to go. When I got there, I found out that they were having their end of season clearance sale and they were now 1/2 price.
I should have bought all that they had
, but settled for 1 orange and 2 yellows.
Check your local sources or even the big box stores (just be sure to get there when the stock arrives). Best wishes on your search.
