Iris Flowers from Holland

Iris Flowers from Netherlands are in lovely blues and yellows.



The Dutch Irises have the following values:

  • Low cost

  • The plants are independents.

  • The flowers are unique.

  • The plants can stand right up at all times.

  • Every plant carries 2 blossoms.

  • Flowers last long.

  • No care is needed if you plant them in a row and 2 inch (about 5cm) from each other.




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.



My Garden Condition:
Lowest night temperature (minus 6°C) was on 1-4-2011

Mid-day from 10 (lowest) to 34°C (highest)

Frequent rain shower

High humidity





Location 1:
North side of the garden in front of the garden hedge
Receiving Autumn to Spring sunshine

6 bulbs (depth of 2 inch) were planted on 20 November 2010 (top left picture 2).

Extras:

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.
