Hi Johnaton
Holland provides the most fresh chilies to the marked in Europe - and there is extensive research and work from both official and breeders beeing done developing cultivars/hybrids which have a large yield, are quick from seed to fruit, that have "standard measurement", have a long shelf live, are resistant to deseases etc.
The chili you bought are almost certainly one of those - specially designed to be grown and sold commercialy - having the appearance and heat level of what could be called "the Dutct chilies" - which in this sence is a group of chili pepper cultivars / strains / hybrids with almost similar phenotype features.
The name Piccantina has me a bit puzzled as the "picant" derives I believe from the Spanish / Italian "hot" and the only piccantina I heard of before was a tomato sauce spiced with mild chili.
I have not been able to find a the "piccantina" in any database as a new F1 hybrid which would be normal if a breeder put the time and money to develope it...
Oohh.. .. just saw you updated with the name Starflame and Fireflame
I'll do a little digging as well then
But do try to take seeds from the red and yellow - mature ones. All though labelled F1 I had several "super marked Ducht chilies" grow true or almost true .. if you have the space it is at least exciting to see what comes out of it .
