Spec21 is a plant specification guide for contemporary, commercially produced landscape plants. The aim of the guide is to provide concise plant specifications so that the expected quality of plant material is clearly defined. In our view plant material should be regarded the same as any other material on site and have clearly identifiable specifications
A landscape plant needs to be well structured, robust and vigorous. The structure is the most important factor, without a good structure a plant will never achieve a good shape and form. By providing detailed specifications on pot size, indicative plant size and proportional structure, Spec21 aims to ensure that the plant material is suitable for the task.
The varieties selected for inclusion in Spec21 the guide are proven commercially produced plants for successful professional soft landscape designs. It is not a definitive list of plants but a list of key varieties for commercial landscapes. Our aim is not to restrict the design palette but to provide a strong reliable ‘back bone’ which can then be enhanced.
The guide is regularly updated with new and improved varieties and any varieties that have not performed as expected on site are removed from the lists.
Spec21 works within the HTA National Plant Specification and the aim is to produce a best practice guide, using the pot sizes and specification we would recommend for best value sustainable landscape plantings.
‘It is quite clear this won’t constrict our design ambitions, rather the reverse as we will have confidence that the effects we want to achieve, can be achieved and will last.’
‘Like many practices our new young members of staff have yet to gain experience and knowledge of the use of plants in soft landscaping. Robin Tacchi Plants has proved invaluable’ Townshend Landscape Architects
‘ We would not hesitate to recommend robin tacchi plants as horticultural advisors, growers and landscape plant specialists. Spec21 must be of considerable educational benefit to new and established members of our profession.’ Clive McDonnell Landscape Design
