Unless you obtain the growing plant in a pot, which is next to impossible by mail order, it is best to buy tubers when they are dormant. Before ordering determine when the tubers went into dormancy in order to know how much longer you must provide dormant conditions. The dormant period can be extended in most cases so that you can synchronize the plant's growth cycle with your particular conditions. That is, if you can
provide the correct cultural conditions during the spring and you get tubers during the winter that have already had a sufficient dormant period, they can in some cases be kept dormant for a few more months and then potted and allowed to grow.
Since the tubers of many Drosera species are found deep in the ground, they are probably in moist soil even though the surface soil is dry or parched. Wondering if these plants really need a dry period, 2 years ago we planted and kept tubers of 10 species of tuberous Drosera in wet soils the year around. These test tubers are completing their second season and their growth and size are excellent. A few more seasons of growth in wet soils will reveal if this method is successful.
Flowering, and therefore dormancy, are apparently initiated by photoperiod. The days are shorter during the growing period than during the dormant season. There may be a biological clock involved because some species start to grow even though the soil is parched. We have stored tubers in a plastic bags at 38°F (3°C) and even under these conditions some species start to grow.
The easier species to grow in this group include D. menziesii, D. stolonifera, D. auriculata and D. peltata.
