On the night of 4 June, plant thieves took "all our specimens" said Seiont’s Neil Alcock.
He said among the specimens stolen were new launch Heuchera Morello in a 7.5 litre pot, a new hebe "due for launch soon in a blue glazed pot cannot be bought anywhere yet" a Cordyline ‘Pink Passion’ and several other plants.
Alcock said: "We had most of our display plants for the HTA National Plant Show stolen last week. They had been moved to a cooler part of the nursery so they would look their best. The biggest losses have been Heuchera Morello and Cordyline Jive. A single as yet unnamed variegated Hebe was also taken. The production plants are unaffected.
He added: "We think it was random/opportunistic, whoever took them don’t know what they have got!"
Alcock is now frantically getting new plants ready for the 24-25 Stoneleigh event. He had dozens of retweets of a plea for people to look out for the stolen plants.
