| Positive | On Oct 15, 2007, kqcrna from Cincinnati, OH (Zone 6a) wrote: This plant wintersowed very well for me. Blossoms have been as large as 5 inches in diameter. I think the green eye makes it particularly pretty and unique in the sunny garden. |
| Positive | On Sep 3, 2005, flowercrazy39 from Manchester, NH wrote: So far I like this plant a lot. Hasn't rained hardly at all here in southern New Hampshire so some of my flowers have had a hard time to bloom. But it's growing and I've seen at least two blooms so far and they last a really long time. |
| Positive | On Oct 14, 2004, lmelling from Ithaca, NY (Zone 5b) wrote: I purchased seeds for this plant in 2001, where they listed it as an annual, but the Irish eyes have been coming back each year to delight me. They reseed prodigiously and I find that I end up pulling up or moving many seedlings during the summer, which have strayed into the other plants surrounding them. I suggest that you give these plants plenty of room or plant them as part of a cottage style garden. They will probably need staking midway through the summer as they can grow up to 4' tall! |
