Where I have the most trouble is determining wht soil /earth type , Wild type it can take two or three full seasons to get a bloom , then usually the following season they bloom full and then do not return , (previous expressed here) They like sunbaked , hard as brick earth , which makes them ,undetermined as to starting from seed ,,
Threadleaf like the Center stage , (I will show a bloom again later ) are more perennial , their a little easier to keep , rarely seed true , difficult to get runner starts from , things like that ,,
I have seen the new introductions , and think they are delightful ,
Only rambling some thoughts off ,,,
I hope you have lots of success with yours ,
