"The experience of Ronnie Rawlins illustrates the difficulties facing breeders, for after making more than 1000 crosses, he found only two seedlings that showed promise. Both come from ‘CHEWtingle’ crossed with ‘Scrivbell’, a seedling which includes ‘Flower Carpet’ and ‘Baby Love’ in its lineage. Both repeat their flower."
