robbenloe It's an agave. Not sure of the species, but it looks like Agave x ferdinandi-regis x scabra or Agave 'Sharkskin' (Sharkskin Agave). There are hundreds of different species. Most agave can live in and require full sun to do their best. But there are a few that can take less light. But most perform better with full sun. Hope that helps.
Where's the water? Unless your area is receiving regular precipitation, monitor plant root zones for whether the soil is drying out. While winter is cooler, the humidity is often lower, and windy periodswith sunshine can serve to dry out soil beyond what's ideal for healthier plants. The reverse can also be true. During wetter winters, be careful not to add to any potential problems with too much soil moisture, which can lead to rotting. Accent plants such as cacti and agaves are especially sensitive to overwatering. Either extreme of watering — too little or too much — creates a plant that is unnecessarily stressed and susceptible to premature death, therefore adding to the cost of your garden.
