Mexican Evening Primrose (Oenothera berlanderi syn. Oenothera speciosa)
Aren’t these flowers just lovely?
I do love pink flowers. 
Our local big box nursery had quite a few of these on display over the weekend.  
Mexican Evening Primrose is a groundcover the produces beautiful pink flowers in the spring.  They are drought tolerant and hardy to Zone 5 through 9.  They do not require fertilizer and thrive on neglect.
 
Now you may be wondering what secret it is harboring.  Surely a plant with such beautiful flowers cannot have anything to hide, can it?
Well, I discovered it’s secret years ago as a new homeowner.  I was in heaven over having my own garden for the first time.  I discovered these pretty plants at my local nursery and brought some home and planted them in a raised planting bed.  
 
They grew very well and although they were fairly boring when not in bloom, they more then made up for it in the spring when they were covered with pink flowers.
 BUT, one year after I planted them, I began to notice them coming up in my lawn, adjoining beds and the cracks in the driveway.  It was then that I found out that they could be invasive.  They spread by stolons and by seed.  **It was experiences like this one that I had as a new gardener that motivated me to obtain my degree in horticulture.  However, I am still learning as I go along and just when I think I know all about a particular plant – one will surprise me by doing something different 😉
Now, I am not saying not to ever use Mexican Evening Primrose in the landscape.  They do have a place in the landscape.  For example, they do very well along dry hillsides and other areas where their growth can be contained in a particular area.
What I do recommend, is to research a plant before you decide to put in your garden.  Mexican Evening Primrose can be invasive in a residential garden, but can be the answer to a difficult, bare hillside.  This goes to prove that just because a plant has a “pretty face”, doesn’t mean that it is delicate.

**Butterfly Update:  Guess What?!!  The butterflies emerged for their chrysalis.  I will post about them soon!

I hope you all have a wonderful week!
