Gollum Jade (Crassula ovata): A monstrose sport that first appeared in the 1970s at Abbey Garden. In warm climates (zone 10+) it can grow into a large shrub, but it really shines as a low maintenance indoor plant. When grown in a small pot, its woody branches even lend themselves to bonsai pruning.
Like Hobbit Jade, the other member of the "Tolkien / Tölken Group", the leaves of Gollum Jade curl in upon themselves and have round, suction cup-like tips that turn red in direct sun. Jade plants can bloom in winter with impressive clusters of delicate white flowers.
Gollum Jade tolerates extended drought and should be kept in containers with drainage holes and gritty, well-draining soil. Water deeply, but only when the soil is completely dry. Once your plant is mature, it can easily be propagated from stem cuttings (more info).
Soft succulents will not survive a hard frost, but if there is a risk of freezing temperatures they can be brought indoors to grow on a sunny window sill or under a grow light. They need ample sunlight, great drainage, and infrequent water to prevent rot. Pick containers with drainage holes and use well-draining cactus and succulent soil with 50% to 70% mineral grit such as coarse sand, pumice, or perlite. Water deeply enough for water to run out the drainage hole, then wait for the soil to fully dry before watering again.
Crassula can show tiny white or black dots on their leaves. These are healthy, water-transferring pores called "hydathodes" and not a sign of disease.
