Cape Forget Me Not Seeds - Anchusa capensis Flower Seeds

Under good conditions, with cool soil around 60 to 65 degrees Fahrenheit and consistent moisture, you can expect to see seedlings emerge somewhere between 14 and 30 days after sowing. That said, germination timing varies considerably depending on your climate, the quality of your soil contact, and how steady the moisture has been. If nothing appears after four weeks, give it more time before concluding the seeds have failed.

Anchusa capensis is native to South Africa where it grows as a short-lived perennial, but in most temperate gardens it behaves as a biennial, forming a leafy rosette in its first year and flowering in its second. In climates with cold winters, gardeners typically treat it as a half-hardy annual by sowing it fresh each season. Either approach works well, and the plant's tendency to self-seed often means you end up with a self-sustaining colony without much effort.

Yes, Cape Forget Me Not is a reliable self-seeder when it is happy in its location, and in warm, dry climates it can naturalize quite effectively over time. If you want it to spread, simply allow some flowerheads to fully ripen and shatter seed before cutting them back. If you prefer to control where it grows, deadhead consistently before seeds fully mature.

Anchusa capensis is considered relatively deer resistant, likely because deer tend to avoid plants in the Boraginaceae family that contain rough foliage and certain alkaloid compounds. It is also a genuinely drought tolerant flower once established, making it a practical choice for water-conscious gardens or areas with hot, dry summers. It is not indestructible in extreme drought, but it handles dry spells far better than most cottage garden annuals.

You can grow Anchusa capensis in containers, though it does best in larger pots that give its taproot room to develop and that dry out a bit between waterings. Use a well-draining mix, place the container in full sun, and be aware that potted plants will need more attentive watering during heat waves than they would in the ground. Smaller containers tend to stress the plant and shorten its blooming period.

The flowers of Anchusa capensis are sometimes used as a garnish in the same way as borage flowers, and the blue color is visually striking on a plate. However, the plant contains pyrrolizidine alkaloids, which are compounds of concern for liver health with repeated consumption, so it should not be eaten regularly or in quantity. If you are interested in edible flowers, it is worth researching this carefully before adding them to food.

In cooler temperate climates, early spring sowing directly outdoors once frost risk has passed is the most common approach. In mild or warm climates with minimal frost, an autumn sowing works well and allows plants to establish over winter for strong spring and summer blooming. Avoid sowing into very warm soil in midsummer, as heat tends to slow or inhibit germination for this South Africa native.
