I wait until the seedlings are large enough to form the first bud and to handle, then move 3 of them to a favorite spot for them to produce a maximum show during the summer months. Some years produce more seedlings than other years, but never enough to be objectionable. They are so tiny that I just pull the extras along with the crabgrass seedlings & other Spring weeds.

I've found it to be an excellent "filler" plant in sunny spots between shorter perennials that bloom only once during the summer.

In the fall after a hard frost, I turn the remainder of the plants upside-down and rather harshly brush them over the ground to make sure they leave some seeds for next year, then trust Mother Nature to "do her thing" with them.

But where on earth did this notation about it come from?
< Plant has spines or sharp edges; use extreme caution when handling. >
The thin little stems & leaves just don't have such things (and there's no doubt that my plants are the same as those shown in the photographs posted here). And "if" they do, then they must be microscopically tiny.

I found it last year & had planted it amongst my shade perennials. I was gone from Feb to July 21 and when I started weeding out my garden, I found a little one growing ! I don't know if it came from seed, or overwintered. My guess is it overwintered. I'm really going to be watching this baby - and will try to slip it also.
I remember reading that the seeds are not viable, but I also read above that for some, it reseads readily. I'll see what happens here.

Ya'll must be talking about a different Dahlberg Daisy than I have. I love the plant but I've never been able to get it to start from se...Read Moreed. Every year I buy them from our local nursery and collect seeds in hopes of some of them germinating. It is definitely Dahlberg Daisy - but they never germinate and I never have volunteers come up from where they drop their seeds. I would love to be able to grow them from seed. What is ya'll's secret? Does it need stratification? If so, it seems like the seeds dropped would come up the following Spring. Oh, I'm in North Texas - Denison Zone 7 (I think).

Help please.

This little plant is cute at first, but spreads through rampant reseeding. The seed heads are similar to dandelion and are carried on the...Read More wind, so they come up everywhere. My neighbors that know I have it have ended up cursing my existence because they are constantly having to rip it out of their yards. Most of the seeds drop down under the very dense mat of fern like foliage, and so reseed heavily in the original place they were planted. Once you have it, it's nearly impossible to get rid of unless you spray with Roundup or continuously pull the seedlings which come up constantly. The seeds are also very messy when they get on the ground, so I don't recommend this near a swimming pool at all. If you want a groundcover type plant that reliably comes back from seed and covers a huge area, then this is for you, but if you are going to try to keep it confined, good luck!
