It wilts almost completely down during the hottest part of the day, (which is nerve wrecking to see) for crying out loud, if your thermometer read 103 farenheit or 39.4 celcius you'd wilt too. Therefore I have watered it everyday, this area also drains quickly. Remember, we are in a drought, over 11 inches short of rain this year. Could be the driest May on record. There is a wild Lupinus villosus--Lady Lupine which I actually featured on April 27, 2011 growing wild on my SIL's property, they are not the same species.
I have two more in this same area, no bloom stalks yet. I have one in the full sun garden mixed in a patch of Forget-me-nots..the soil there retains moisture longer so I have not witnessed any wilting, it also doesn't have a bloom stalk, yet. I will planting these again next year in an area that receives some mid-day shade...Jean over at http://msgreenthumbjean.blogspot.com whom I'm linking with has a patch of purple lupine blooming. Now let's see if I can be successful with collecting the seed.
Today I am Thankful for the nice holiday weekend we just had.
