Difficulties or problems when growing: Sensitive to overwater
Planting season: Spring to summer in hardiness zone 10a, spring to autumn 10a-11a, all year hardiness zone 11+.
How to plant: Planting in location with good drainage, the plant doesn’t like and might die if will sit in puddle so in rainy location better to grow above the ground level and use raising bad, better to dig bigger hole and put in the soil well ventilated soil, better to plant it in sandy soil.

Water requirement: Small amount of water / Average amount of water, if the leaves become soft and start to weep need to add water
Light conditions in optimal condition for growing: Full Sun / Half Shade / Full Shade in hardiness zone 10a need to give more than full shade, the plant might die overwinter
Is it possible to grow indoor as houseplant? Yes
How to care indoor: When growing indoor need to choose location with light and also need air ventilation once in few days, better not to put the plant next to heater, and water less in regular condition but with air condition and heater need to increase the amount of water

Saving seeds and care until sowing: Dry and dark place in room temperature
Sowing season: Spring will be better but possible in hardiness zone 10a spring to summer, in hardiness zone 10b-11 spring to autumn, hardiness zone 12+ all year, better in hot summer location not to sow in the summer
How to plant: Sowing in soil with good drainage and light, possible sandy soil but size of the particle need to be not too much big, possible to sow in potting mix, peat soil and vermiculite (when sow in vermiculite need to put only the layer of the seeds and under this to put soil
