Amsonia ex ‘Blue Ice’ (Bluestar) [8 Seeds]


Germination Information: I recommend these seeds for experienced seed-starters only, because they may require some experimentation and patience. The easiest approach is to purchase and sow the seeds (just barely covered with growing medium) in fall to late winter, setting them outdoors in a spot protected from mice so they can get a chilling period and then germinate when conditions are right in spring.

If you sow after February, set the pot in a plastic bag in your refrigerator for 2 to 3 months before moving it to a warm, bright place for germination. (Remove the bag if the pot will be exposed to any direct sun.)

‘Blue Ice’ bluestar (Amsonia) produces clusters of light blue flowers in late spring to early summer, on spreading plants that typically reach 12 to 18 inches tall. This popular selection is apparently a hybrid, but its origin is uncertain. Most sources say that it doesn’t set seed, and I would have agreed with that. But last year, and this year, I did find some seedpods and was able to collect some viable-looking seeds. These are NOT seeds of ‘Blue Ice’, but rather, ex (out of) ‘Blue Ice’. If you want to grow the true ‘Blue Ice’, you need to start with a vegetatively propagated plant. If you collect bluestars and/or enjoy experimenting with unusual seeds, these seeds could be very interesting. I sowed a batch for myself in the fall of 2019 and ended up with six plants in 2020.  I’m hoping they will start flowering in the summer of 2020, so I have a better idea of what they’ll look like. Full sun to light shade. Perennial; Zones 3 to 9, probably.

Harvested in October 2020. At least 8 seeds.
