Am I expecting too much with this title?

Dandelions
 
When the first one left
for school,  mother cried,
walked him to the bus stop.
With the second and third
much more a chore of joy
than a pang of regret.
 
First year of college came
with a mother’s pining
and hugging each time
he came and went, but
with the second and third
less need for sentiment.
 
Marriage took the oldest
and mother grieved deeply.
She lost his youth to life
and wife and family.
With second and third
she gained daughters-in-law.
 
Silver hoary heads shine
along meadow ridges
in ageless repetition
sowing new seeds
on the wind.

Hey Dennis...nice poem.  I like the journey.  I don't think you are asking too much from the title at all.  

I see a couple "weeds" that you might consider:

1.  Second stanza has two "came"s  (I like the internal rhyme in this stanza...sneaky)

2.  "Took" in stanza three feels like "death" and perhaps that is the connotation you desired.

3.  "Silver" and "hoary" are the same basic picture.  Maybe the redundancy works for the population of dandelions as image.  Also, it reads as though the old are doing the current re-population rather than enjoying the work of their progeny.

I like the title.  I don't like  hoary.  How about bright or sunny heads.  Hope.  I paused in reading the second line:  mother.   I would say the mother or Mother.  That way we grammar cops don't pause.  How about joy chore than chore of joy.  Either way it's oxymoron which I like.  Do you really mean sentiment?  Less need for feelings?  showing of affection?  Might check this word's meanings.  Is that what you mean?  Or do you mean:  less need for holding close?  I don't think you need deeply.  And how does the loss actually happen?  I think it's wife and family and life.  I'm wondering if you need in-law.   Maybe daughters would suffice.  Or in-law daughters.  I know I tweeked a good bit, but Dennis, I like it.
