Iris Flowers from Netherlands are in lovely blues and yellows.
I bought a packet of brand new bulbs on 20 November 2010 (above top picture 1).
I planted them on 2 occasions and in 5 different locations.
The purpose is to find out how far I can stretch the flowering time.
And in this way, I can plan our flower garden landscape properly.

Location 4: Two plants were blooming on the day 107

If two flowers blooming together in one bud (above right picture 39); remove the faded flower as soon as possible; otherwise; the second flower could not expand (picture 40).
Alternatively; you can also sprout the bulbs in house in mid-February; and transfer them in the garden pots later in the early March. In this way, you can enjoy your blue flowers in the early July.
