Easy: Great for Beginners!

Intermediate: Usually requires more work, such as: pruning, support systems, fungal/disease problems, and/or pests.

It might need special care such as: doesn’t like humidity, and/or might need special soil. In addition to things such as: pruning, support systems and/or pests/diseases.

Things to know about edible flowers.

Treat any edible flowers that you plan on eating like any other herb or vegetable in the garden. Avoid using systemic poisons on the plants or nearby soil. Systemic poisons will be absorbed by the plant and distributed throughout the tissues, making the plant poisonous. 

How to Cold Stratify

Stratification: 

“For seeds that require a chilling period before germination, like some perennials, all you need is a refrigerator and a bag or container filled with perlite, vermiculite, sand, or seed-starting mix. (Mark the seed variety name on the bag.) Moisten the mix, add the seeds, and place in the refrigerator, NOT the freezer. Stratification requirements vary by species. Some plants prefer 2 weeks of cold treatment, some require 2 months or longer. Regardless of the length, never let the seeds dry out during stratification.”
