"The National Plant Collection® of Fragaria vesca


The National Plant Collection® of Hakonechloa

















Polemonium

The collection was recognised in 1992 where the Polemoniums were grown in a small garden in Ebchester, County Durham, UK. In 1998 the entire collection was moved twenty five miles east to Trimdon Grange, where the winds blow straight off the north east coast.The collection was awarded Scientific Status in 1999, one of only 35 of the 650 plus collections in the UK. The collection is run by a husband and wife team, David and Dianne Nichol-Brown, Dianne being the botanist with a first class honours degree in plant biology, a lecturer in ecology and conservation and an interest in the genus since 1985, David ensures that everything runs smoothly and manages the family nursery.

The collection was awarded Scientific Status in 1999, one of only 35 of the 650 plus collections in the UK.

We have 70 plus species and cultivars in the Polemonium collection, with new cultivars being developed regularly. They range from 10cm Alpines to 120cm herbaceous and can be grown in a variety of locations including under conifers.

The plants are often incorrectly named by nurseries and seed suppliers, Mainly P. boreale, caeruleum and pauciflorum are sold under various names. In tests we have found approx 90% of all seed is incorrectly named, this includes seeds from some of the large reputable suppliers.

In 2002 the Collomia and Gilia were added to the collection, these require similar growing conditions to Polemoniums. We have visited many gardens and sites in our research including Royal Botanical Gardens Edinburgh as shown in the picture

Hakonechloa

November 2006, we were awarded collection status on our Hakonechloa(Japanese Forrest grass), not a relative of Polemoniums but require same growing conditions and they do look good together.

Fragaria


null

The National Plant Collection of Fragaria vesca was added in 2016 with an extensive range of cultivars providing fruit all the year round. Some plants are purely ornamental-for example Fragaris vesca var. monophylla -the first mention made of this Strawberry, is in Duchesne's Histoire naturelle des Fraisiers, with its complete history, and from which we learn, that it was originally found by him at Versailles, in the Year 1761, from seeds of the Wood Strawberry.

From France this plant has been conveyed to most parts of Europe;, but it is certainly very little known in this country: in the 14th edit of the Syst. Veg. of Linnaeus, it appears as a species under the name of monophylla, originally imposed on it by Duchesne; Linnaeus, however, has his doubts as to its being a species distinct from vesca, and not without reason; for it can certainly be regarded as a very singular variety only; its origin indeed is a proof of this; in addition to which plants raised from the runners will sometimes, though very rarely indeed, have three leave instead of one. Fragaria vesca var. muricata (see picture)has green spines instead of achenes, introduced by the botanist Tradescant.
We grow over 20 taxa in pots and containers and in beds for production
