Growing from seed is definitely worth it. It is the only way we get new varieties introduced. Seeds do not grow true to parents. They can be any color. I did have 3 that bloomed last year at 15, 16, and 18 months. I know this is not characteristic of what is normal, but I am am very vigilant about up potting constantly and trying to give ideal growing conditions. I'm sure I will not always be that successful. All 3 of those seeds were from the same parent Sorrento Stripe. I do have a seed pod on the one that bloomed at 16 months. They are right around 2 years old now. They were planted March 2021.
