Germination of
Amorphophallus sp.
Arum Mix, Calla Lily, Lily of the Nile.
The seeds of Amorphophallus sp. should be sown in well-draining soil, preferably with perlite or sand mixed in to improve drainage. The seeds should be planted at a depth of about 1/2 inch, and kept moist but not waterlogged. A temperature range of 70-80�F (21-27�C) is ideal for germination, which typically takes about 3-4 weeks.
Some of plants may have very have specific germination requirements that may not be covered in these general instructions.
Many seeds require pre-treatment before sowing which we try to list here when we can, but this information may not be present here. Germination times and germination temperatures are to be a guide only. Many factors can DRASTICALLY affect this.
It's always a good idea to research the specific germination requirements from multiple sources for each plant before attempting to grow them from seed.
