Happy St. Patrick's Day!

On 364 days of the year, I consider this a pesky, invasive weed.
Today: It's all about shamrocks!
Name: Creeping woodsorrel, Oxalis corniculata,
Leaves:  Three heart-shaped leaflets which open and close in intense light and at night.
Bloom:  Five small yellow petals atop of slender and tender stalk.
Growth Season:  Year Round (!)  No wonder this weed gets such a strong hold on my hill side.
Reproduction:  Creeping and rupturing seedpods which can expel between 10-50 seeds.
Locations:  Turf, ground covering, gardens and most annoying between pavers!
