THE COLLECTION


The National Collection was formed in 1983 by David Brown in Oxfordshire where is stayed until 1989 before then being reformed in Cornwall by David in 1994.


Subsequently The Collection moved to its present home on Varfell Farm near Penzance.

In 2009 the National Collection displayed at the RHS Chelsea show. This was the first time dahlias had been shown at Chelsea for 25 years and we achieved a gold media and the President’s Special Award for the best Floral exhibit.

In recent years the Collection has also achieved gold medals at the RHS Hampton Court , Tatton Park and Westminster shows.

Dahlias have enjoyed a great resurgence in recent years moving on from memories of allotment plots to use as feature plants and being the best source of late summer and autumn colour in any garden.

Dahlia MerkkiiDahlias can be grown in most soils and situations and can also be grown in pots for use in smaller gardens and on patios.There are also many dark foliage varieties which add variety to may garden settings as well as helping to set off other plants.

Mike Man under the D. ImperialisWe have a number of Specie forms available from the delicate D. Merkkii (shown left) to the potentially huge tree dahlia D.Imperialis (shown right).

Dahlias are classified into nine different forms and each dahlia in the Collection is identified by name , form and colour and each has a unique catalogue number.

Dahlias are a beautiful all round flower - by choosing your varieties you can have cut flowers, borders and terraces full of colour well into late summer AND early autumn.

Colours range from the palest pinks through to chocolate box reds; fiery oranges to purples and foliage from green to dark bronze.

You can search, on this website, by name (or part of name), catalogue number, colour, classification (Variety) or a combination of search criteria (eg Decorative and Red).
