Too early and cold. Mine although all sprouted will keep them in until First week of May,

Hosta is easy to grow from seed but they're slow growing. I winter sowed hosta seeds last year and got great germination. They got almost 2" tall before going dormant for the winter. That's too small (in my mind anyway) to plant out since they'll be too easy to forget about and (for me) to step on. I potted them up to gallon size nursery pots and kept them on my shaded breezeway for the summer. I'll decide whether or not to plant them out this year depending on how large they grow. Aren't they the cutest little sprouts?
