Here and Gone (late-blooming lilac bush)

Lilacs are known for blooming around Mother's Day.  Our new bush (Barbara) was planted in honor of my mother-in-law Ruth.  About a week ago, I saw a small bud starting.  I Googled it and it's not unusual.  But this didn't last long.  Within a week it was gone and it's the only one I've seen.  But it's growing very well and I've been covering it to protect from the deer.
