COLLECTING AND PROPAGATING SEED


Seed pods were collected in October with stems of � metre. These were hung up in bunches of named varieties in the greenhouse with frost protection. (The pictures here were taken on November 6th, 2004 prior to frost damage but the flowers by this time are obviously very poor). In 2003 we had our first frost in Tiverton on October 8th.
 

When the pods were dry and the seed ripened the pods were opened and the seed collected. Only firm seed was selected and the yield from each flower head was stored separately in small paper boxes in a cool dry drawer.

 Approximately 40 to 50 seeds were taken from each head.

 


 

In late March the seeds were sown 10 mms deep in trays of peat based compost, 144 per tray.
 
Germination started after several days.
 

As soon as the seedlings had reached the stage when they were big enough to be potted on they were transferred into modules of 12 segments per seed tray
 

At this stage the plants were ready to harden off. Close up of sturdy plants with close leaf joints


HARDENING OFF THE PLANTS

This was achieved by storing them in a tunnel, which had frost protection.
 

PLANTING OUT
 

The seedlings were planted out between the 7th and 10th of June. The rows shown are Sue Mountjoy (C and U) and Demi Schneider.

INFORMATION COLLECTED.

When the first flower from each plant reached its prime (in the case of collerettes this is when two rings of pollen bearing stamens are showing) the date was recorded and a photograph taken. The seedling number was assigned and the colours and the number of main petals and the length and substance of the collar petals or their absence, written down. Any other eccentricities or significant information was added as considered of interest. This included the size and regularity of the blooms, the strength of the stems and the size of the plants.

If a seedling was considered to have exhibition potential it was marked either as M or T. The former indicated that it was regarded as being definitely worth growing in 2005 while the latter indicated that a decision should be made after a second or third flower was judged. All seedlings regarded as being unworthy of being grown again had an X recorded by the assigned number and were dug out and discarded immediately, leaving more space for the good specimens to mature. Quite a few seedlings were rejected that would have been retained in former years as my standards have risen while some were very like established varieties.

Recording began on the 13th July and continued until 29th September � a period of 78 days. Some �first flowers� came out after the 29th. An arbitrary decision was taken that such late flowering seedlings would probably not produce flowers in the prime exhibition period.

Inevitably the photographs vary greatly in quality and clarity as the conditions varied from bright sun to heavy rain and strong winds. Regretfully, a few flowers were not photographed due to human error!


I wish to record my thanks to my wife, Maureen, who daily acted as scribe and arbiter of �colour� and resolutely persuaded me to keep only the very best specimens.

On the next page is a copy of a typical record sheet.
