General Asparagus (Asparagus officinalis L.) can be grown in a wide range of soils and under various climatic conditions, but it thrives in fertile, well-drained soils. Roots can be at least six feet deep, but they will not tolerate saturated soil conditions. Plants can tolerate temperatures from -40° C to 46° C, but specific varieties are adapted to cold, warm, or tropical environments. Jaleo (Vilmorin) is an all-male hybrid adapted to tropical (low-chill) environments. UC157 (Druk seed) is also an all-male hybrid adapted to warm/dry, irrigated regions of California, USA. Merry Washington (Druk seed) is an open pollinated variety with a broad range of adaptation.
