Super easy to grow in the desert, needs full sun loves hotter weather and tolerates coolish weather. I water it every other day when it’s hotter outside and every 2-3 days when it’s colder. It’s a little forgiving when you forget to water it and it perks right back up when you finally give it water. I love this plant, I grew it from seeds and got to see it bloom flowers after about 2 and half months.
