Anyone know of anywhere selling these ? The lack of Google hits suggests no, but I thought it's worth an ask ?
By the way, it's Sungold. Not Sundream. Sunblush. Sunstoke. Sunscreen. Or any other words preceded by Sun which Tesco/Waitrose/Sainsburys try and palm off on us.
You used to be able to get them about 10-15 years ago, and then they disappeared (probably because they were so nice). The fact you can get loads of seeds online (and nursery plants) suggests they are not cost-effective to grow
