Ascona is RZÝs latest contribution. Both Sesam, (Dark Lollo Rossa) and Raisa are also theirs. Ascona is a ýBataviaţ type, noted in France for its crunchy, juicy texture and sweet nutty flavor. The thick heavy heads are an intense dark red overall. When hearts are allowed to form, the green in the heart gives a perfect red-green balance for a colorful salad. Ascona is resistant to tipburn and basal rot. It is also slow bolting, a special property of most Batavias. It is recommended for Spring, Summer, and Autumn crops. Resistance: Bremia NL1-5, 7, 10 and LMV.
