History of Gigantic family
Gigantic Raised by Len Shoesmith and released in 1962. Alan Wren
registered the Silver sport in 1972. Although this was the original
seedling that was raised by Len Shoesmith, the Floral committee of the
National Chrysanthemum Society in their wisdom insisted that the silver
was the sport. In effect the Silver has been registered twice and
Gigantic has never been registered.
Both Norman and Harold Walker registered the Golden
sport in 1979 and Tony Winter had the Amber sport. This was registered
in 1981. Primrose and Yellow sports have also been registered but these
have proved to be synonymous with the Amber when grown cool.
I grow half the Amber Gigantic and Silver Gigantic on
1st crown and half on 2nd crown. The Gigantic and Golden Gigantic are
all grown 2nd crown. The reason for this is that I am unable to avoid
these blooms going past their best if the buds are secured before first
week of August, whereas the Amber and Silver are much better at holding
on if they are on the early side.
For 2nd crown I root 10th - 20th of January, the first
stop on 21st March. I allow two breaks to grow, then stop one of these
on the 10th of May and the other on the 20th May. Later, when the plants
are carrying two breaks after the second stop (one earlier than the
other by a week to 10 days) choose the break with the bud secured in the
first 5 days of August (if possible) and remove the other break.
For 1st crown root 1st March and stop 20th May. I find
a 10" pot ideal for Gigantic as the biggest blooms come from big
plants with heavy wood. They take full feeds, I use Vitax Q4 up to bud
and Q4HN or Chempak number 2 once the buds appear. If the weather is hot
and the wood is ripening I swap to the HN or Chempak no2 to keep them
producing heavy wood.
