My predictions for succulent plants, gardens and design will help you stay on top of trends and maybe even make money from the plants you love. Although it can reach 33 feet in height, it will still be small if placed into a small pot. The soil surface should be at least 1 1/2 inches below top of pot when filled. They protect your pot's surface from being stained by the soil. They look great draped over this minimalistic, modern pot with their long, trailing stems. However, under the right conditions they are capable of living for over 200 years.
