Gardeners' Notes:

Positive txgardengranny On Mar 7, 2015, txgardengranny from Dallas, TX wrote:

Planted two of these purchased at local nursery Spring of 2014 and they thrived in Dallas TX heat. They got full sun from 9 a.m.-3 pm and good soaking twice a week. Plants actually grew to 24" and spread laterally to about 36". They bloomed nonstop from shortly after planting to first frost in late October. The blooms trailed off the last two months but I did deadhead the finished blossoms all summer.

Would like to know how long it takes to get to 4inches high after it sprouts. Would like to start from seed but don't want to start it too early. Thanks.

I'm new to this plant. I like blue flowers! Seeds were sown in spring, and the flowers started to open this week, 4 months later. There are plenty of buds, so I'm looking forward to a summer of them.

I've really enjoyed this plant this year, I winter sowed it from seeds earlier this year. It has grown like crazy and was covered with hundreds of flowers that kept blooming until late fall. A real winner in my garden.

I start them early inside and they bloom all summer and well into fall. Some years they self seed in my zone just enough to be a welcome surprise.

Positive Ladyfern On Sep 1, 2003, Ladyfern from Jeffersonville, IN (Zone 6a) wrote:

This is a very nice plant if you can wait until August for it to fill out and begin blooming. At that point, though, it's well-branched and the foliage is attractive. The flowers seem to close up at night.

Neutral talinum On Aug 9, 2001, talinum from Kearney, NE (Zone 5a) wrote:

Sometimes called Manaos Beauty, this bushy perennial native to Brazil is a HHA in the north. Coming into bloom in a rather short period from seed, the lavender-blue, button flowers to 1-1/4 inches are long lasting and borne continually until frost. The flowers resemble tiny Canadian thistle flowers. The refreshing resinous pineapple scented foliage would be a good candidate for wreaths or potpourri.
The plant mounds 2' high to 3' across. It will occasionally reseed itself.
