Helping Children Grow at RHS Chelsea Flower Show 2019

The Horticultural Trades Association (HTA) will be returning to RHS Chelsea Flower Show 2019 with a Discovery Zone exhibit titled ‘Helping Children Grow’, promoting National Children’s Gardening Week which takes place between 25 May - 2 June 2019.

The exhibit (GPA/104), supported by National Garden Gift Vouchers, will bring to life simple projects which can be used to engage children in gardening whilst fostering their social, emotional and educational development.

Working with National Children’s Gardening Week Ambassador Chris Collins the exhibit will include examples of fun and inspiring projects such as edible planters, a pizza wheel, runner bean tipis and a wildlife hotel. This will encourage children, parents and grandparents to have a go – either at home, at school or by going along to their local garden centre to take part in an activity.

This will be backed up with research findings demonstrating the real educational and social benefits associated with involving children in nature, gardening and growing.

Alongside the plants required for the projects there will be three new plants submitted by HTA members which will be put forward for the RHS Chelsea 2019 Plant of the Year Award. 

New plants

Nepeta Neptune bred by Kees Jan Kraan and entered by Thompson & Morgan.

Nepeta Neptune bred by Kees Jan Kraan and entered by Thompson & Morgan.
Full botanical name of new plant: Nepeta Neptune ('Bokatune)

This brand new selection of Catmint has a compact upright habit of just 30cm. It is ideal for borders and patio pots. This low maintenance perennial is hardy down to -25ºC and will flower from June to September. Its flowers are mauve blue with beautiful dark blue spots.

Kees Jan Kraan started this breeding programme in 2011. The aim was to find a more compact Nepeta kubanica whilst still keeping its strong habit and beautiful blue flowers. It culminated 7 years later with Nepeta Neptune ('Bokatune). It is the first compact kubanica hybrid which now makes Nepeta suitable for smaller spaces, and patio gardens. Large panicles of 2-lipped, tubular, large clean blue flowers appear from June to September. The long flowering period makes it ideal for encouraging biodiversity, providing a four month food source for pollinators. Textural but tough, scented serrated leaves appear in pairs on upright stems.

Ajuga Princess Nadia bred by Nadia Plants and entered by Thompson & Morgan.

Ajuga Princess Nadia bred by Nadia Plants and entered by Thompson & Morgan.
Full botanical name of new plant: Ajuga tenorii PRINCESS NADIA (‘Piotrek01’PBR)

Ajuga tenorii ‘Princess Nadia’ brings together the best variegated foliage and flower spikes of the genus. A controlled creeping habit, true hardiness, and evergreen foliage offers a wide range of garden uses and year-round interest. This truly is a plant for all seasons.

Developed from a sport of purple leaved ‘Valfredda’ in 2013 by Piotr Szdzesny of Nadia Plants Holland, variegated Princess Nadia brings improvements over existing market leading varieties. As a strain of Ajuga tenorii, ‘Princess Nadia’ offers a neater, more compact habit and remains tightly knitted for ground cover. Heavier flowering and blooming in late Spring and again in the summer. New growth emerges as grey purple with vivid pink edges, maturing to grey-green with creamy margins, acting as a refined foil. In spring it produces prolific spikes of royal purple flowers and flushes again in late summer.

Apple Eden bred by Agriculture and Agri-Food Canada (AAFC) and entered by Frank P Matthews.

Full botanical name of new plant t: Malus domestica 'Eden' EU PVR SJCA38R6A74

The first of its kind, Eden is a non-browning commercial and garden apple. Delicious for fresh eating and cooking, it has a whole host of uses including cooking down to a snow-white puree that is sweet, so no additional sugar is needed. It is easy to grow and disease resistant.

Apple Eden was found amongst the breeding progeny of the Agriculture and Agri-food Canada Centre in Quebec. Whilst attempting to breed a hardy scab resistant variety, the scientists stumbled across this interesting non-browning apple variety. The original cross between Linda and Jonamac was made in 1971. Eden was introduced into the UK by Meiosis who worked with Frank P Matthews Nursery to trial the variety and develop it for the UK market. It was released to the wholesale garden centre and nursery market 1st July 2018 and has proved to be very popular.
