I was so excited to have a succulent that crested on it's own in a garden under my care. Although it's great to have a rare plant in your collection, they are often too costly to afford. They had an impressive collection of crested Aeoniums. Crested succulents are a rare but affordable addition to any succulent collection. Like most succulents, standing water must be avoided at all costs, so well-draining soil is essential. If your indoor succulents are not able to receive enough sunlight, a grow lamp is an excellent option.
