Ordered 4 Cardoon Plants that arrived in wonderful condition. Packaging was amazing but Im afriad a little too early for my region. Trying to keep them in the warnth of indoors with as much light as possible and soil reasonably moist but getting spindly and have just lost one. For a zone 4-5, recommend advising shipping for early to mid May. Lightly snowed yesterday. Even forsythia having hard time, imagine. Want to, of course treat as annual. Next year I start them from seed. Im sure I’ll lose miney spent unless warmth finally arrives to stay.
