Commelina Species, Scrub Dayflower, Slender Dayflower, Whitemouth Dayflower, Widow's Tears

Scrub Dayflower, Slender Dayflower, Whitemouth Dayflower, Hierba de Pollo (Commelina erecta) is very invasive in my yard. My mother and ...Read MoreI when I was a little girl were walking to a store on a horribly hot day during a drought. We spotted a plant that had the most incredible blue bloom we had ever seen growing between some rocks. We surmised that this must be one tough plant so we went back to it later, dug it up and took it home. Ooohhhh, what a mistake. It spread everywhere - the flowerbeds, the vegetable garden, the containers. We were unable to totally rid the yard of it despite years of attempting to do so. It has been said that one plant is capable of producing 1600 seeds. The stem joints root also.

When I married and moved to a new house, my mother gave me one of her prized plants that was growing in a container. Little did I know that there was a scrub dayflower seed in the pot. Thus, the "dayflower plague" was spread to my yard. I have been battling it ever since then. Once the roots are established, they become like tenacious claws holding the plant into the soil. If next to a "wanted" plant, usually both plants have to be dug up to completely remove the dayflower. Being unable to separate the dayflower plant from the plants I have in containers, I have to dump the whole container soil with plants out and carefully separate the dayflower roots from the roots of the other plants. In flowerbeds, they spring up everywhere. After fighting them for 60 years, I have not given up the battle - yet. Perhaps, I will die without having won. I have pulled up seedlings constantly since spring. I need to do so again for the 10th time. This isn't counting the established plants.

I have found no weed killer that will kill them yet. This year, I am using a stump and vine killer that I must paint on the cut off stem. I sure hope that it works. For those who think that they want this plant: Warning! Beware!

I found this plant growing between boulders in a very hot sunny area of my new yard in very poor soil where other things would not grow. ...Read MoreLove the flowers, so we kept it when we landscaped that area. Now a tended, watered area it spread quite a bit. Took cuttings and tried it out near the Koi pond in a shady area... Spread beautifully down the waterfall :-) blooms every day since Spring in dry sun, shady water garden, soil-free jars of water in my bathroom and kitchen windows, between rocks near the front door :-) most find it invasive so do be cautious in formal gardens... We enjoy a more natural garden and i LOVE seeing it's dainty blue flowers all over the yard :-) didn't know the name of it until today. Thanx Dave'sGarden!

One of the most invasive WEEDS that grows on the gulf coast. A constant battle to keep this weed from taking over!

I got this in a trade w/ a lovely DGer and it got no respect the first year. I watered when I remembered and it stayed unprotected duri...Read Moreng winter. Having read that it may be invasive, I planted it in a hanging basket to avoid problems down the road. I'm impressed w/ the beautiful blue flowers, but it is not coming out of the pot!
