About Cape Jewels Seeds - Blue Gem

Nemesia strumosa

Seed Type Open Pollinated Seed

Diminutive and sweet, Cape Jewels Blue Gem produces a low-growing carpet of sky-blue blooms to adorn your landscape. Cape Jewels, or Nemesia strumosa, is a true annual that is extremely easy to grow from seed. As long as temperatures remain mild, Blue Gem can produce so many flowers that they almost entirely obscure the foliage from spring into fall.
