I've only had luck with these as an annual in Central FL. They also had to be in filtered sunlight. But I sure enjoy their beauty mixed in my flower pots.

LOVE THIS PLANT. Blooms year around for me with deadheading. Flowers are large on tall stems. Multiplies nicely. Little care. Loves our dry hot summers.

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.

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.

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!

Halfway through the summer I needed to move a group of these to another location and they took off in their new home without even wilting - of course it's been a cool (70's) and rainy summer here in NY. It is now October14th and a few of the group that I moved are still blooming despite several weeks of cool weather and light frosts. Amazing!

They grow well from seed and are hard to find (at least around here) as plants, so I would suggest just buying seed and sowing them in early spring. After the first year you should have enough to move or share with others.

They have done well in my front garden which has well drained soil and full sun. The new location I moved some to is also in full sun but has soil that is more moist but also well drained. They seem to do equally as well there but haven't been through a winter in that location yet.
