Last winter I bought this Euphorbia Bupleurifolia (it was on the expensive side but I thought it was quite cool). Not long after taking it home it started losing all its leaves. This was possibly from shock because of the change in environment and I decided it was probably also a good moment to keep it in dormancy since there was so little natural light around. I gave it no water at all and kept it warm and light. I know this particular species can die from a drop of water at the wrong moment but I decided it was time to wake up. I gave it a good drink of water (the mix is 100% porous stone) and put it in some direct sunlight. As you can see the gamble paid of and it is starting to grow.
