The "Euphorbia ingens", "Euphorbia Eritrea Candelabrum" or "Cowboy Cactus" is a striking houseplant that really brings character to any setting.  This is an ideal house guest as it only requires a little attention but like any Cactus, this guy has spikes - so be careful around pets and children! Care Instructions:  Water every 6 weeks with a litre of water Requires lots of sunlight so place in a bright, hot space.  Can be kept outdoors during the summer months but will need to be brought back indoors before the first sign of frost.  Care Level Rating: Easy  Notes: All large plants come with their plastic nursery pot only and no need to re-pot for four or five years. Ceramic pots are sold separately.
