YEAR 2008

We grow a range of these hardy border plants in small successive batches; this means that the range we have on sale is constantly changing as one variety sells out to be replaced by another. 

Unless priced otherwise, the Herbaceous plants in the following list are either 96p or £1.42 each, depending on the size of the pot in which they are offered for sale.

The majority of plants on sale are likely to be the larger £1.42 size as most varieties grow on better in that size of container. 

Good drainage is essential for most herbaceous plants, the main danger being waterlogging during the winter and spring months (we do have some varieties which actually like moist soil).

If you think that there will be drainage problems sort them out before planting.

Because of the hilly nature of our district this should not be an insurmountable problem; most gardens are on sloping land so there is usually somewhere else in the garden you can divert the excess drainage water to. Rather than thinking that you are replacing one problem area with another, such areas should be seen as an opportunity to grow moisture-loving plants.

The creation of raised or mounded beds is another way of making sure that the upper roots and crowns of the plants are well drained.

Only the main varieties we grow are in the list (heights are dependent on variety).

DELPHINIUM. 60cm (24 inches) to 152cm (60 inches).

Several varieties. Rich, fertile soil is best; they also need full sun and shelter from strong winds.

  SLUG WARNING - if slugs could speak they would ask you to plant Delphiniums. Start putting pellets down (or using other anti-slug measures) before the shoots emerge in spring. The scent given off by the shoots grazing against soil and stone particles on their journey to the surface is enough to attract slugs from yards around. Slugs are not inactive in winter, only when the ground is actually frozen.

DIANTHUS (PINKS). 37½cm (15 inches).

  NOTE - In lupins blue is the genetically dominant colour. If you let them seed the resultant seedlings growing up through and around the clump are likely to have a high proportion of blue individuals. These tend to be stronger growing and eventually crowd out other colours. This is why many clumps of Lupin "turn blue".

LYCHNIS. 76cm (30 inches).

HERBACEOUS NOTE:

Always deadhead after flowering, being careful to remove seedpods along with the dying flowers. Replacement seedlings can be useful, but if you allow too many to be produced they may become "troublesome weeds". Producing too many seeds may also leave you with a weaker parent plant.
