I will have agastache seeds, you know...most likely LOTS of them. I also see the hummers hitting my lepechinia hastatas and I will have seeds from them also. I'm very surprised that the hummers have not been visiting the lobelia tupas...friend Bex said that she's noticed that sometimes if a plant is new to the hummers, they don't visit it untill they get used to it. She plants a lot of grevilleas and the first year the hummers did not use them...not until the next year.
