Draperia systyla aka Violet Draperia

Draperia systyla is in the borage family, Boraginaceae. Kew places its native range in northern and central California. This is the range where the plant is native. It tells us where the plant comes from in the wild. Its climate is temperate. That climate detail does not state its garden hardiness. The native range and garden hardiness are not the same thing. These records give the first, but not the second.

Kew calls the plant a perennial or a subshrub. A perennial is a plant that lives for several years. A subshrub has some woody growth. These terms allow for growth that is not woody, or is woody in part. The records do not give its full-grown height or spread. They give no size in feet or metres. Nor do they describe its leaves or stems. Thus, these records name its growth forms without giving its size or those details.

The Royal Horticultural Society accepts Draperia systyla as the correct name. Its record states that the plant is not native to Britain. The same is true of Ireland. The supplied page does not describe its flowers. It gives no time of year when they bloom. Nor does it give any facts about the fruit. The name and native status are clear from these records. The look of the flowers and fruit remains unstated in them.

The records give its name and wild origin, but little help with growing it. They do not state how much light it needs. They give no soil needs or water needs. They list no hardiness zones for the plant. The note on its temperate climate does not fill those gaps. No garden uses appear in the supplied evidence. These sources therefore leave its garden care and uses largely unstated.

The supplied evidence gives no facts about pests or diseases. It does not say which plant parts, if any, people can eat. Nor does it report whether the plant is toxic. The lack of such facts does not settle either point. Both its use as food and its risk of harm remain unreported in these records.
