Our front yard is planted with Blue Star Creeper.
What started out as a memorial of sorts to my Grandmother,
(she had a "blue lawn")
became over the years our answer to conserving water, and not using fertilizers.
The last few years it has been a "bee gauge" of sorts.
We used to have to warn children not to walk or play on the "blue lawn"
unless they had shoes on, because they were likely to get stung.
It wasn't unusual to have several types of bees working it at a time,
and the buzzing was actually quite noticeable.
This year......... not many bees at all.
niche update:
We finally got the niche placed in the yard, but
haven't been able to find a madonna to put in it.
