Another newbie question
 

Hi
Got another question:

When my oldest iris bloomed this year I was getting 2 flowers per bud. When
the first flower started to fade the second opened up. Has anyone had any
experience with iris doing this? My amaryllis also bloomed with 5 flowers
to each stalk instead of the normal 4. What I'm wondering is if it's
something in the soil or the air or maybe in the rainwater?

Thanks
