The Club’s involvement at the Mark Twain House began in 1970, when several GCH members furnished the Conservatory with plant material authentic to the time of Samuel Clemens. By 1973, the Club had grander plants, voting unanimously to approve the restoration “to its original” of the grounds in celebration of the 100th anniversary of the house. By 1974, the grounds had been restored to their late 19th century grandeur.
