How do I know if my plant is a biennial?

In its first year, the plant will form a low rosette of leaves. It will send up a tall flowering stalk in its second year before setting seed and dying.

Does Scarlet gilia need special soil to bloom?

It prefers well drained, slightly rocky or sandy soil. Very rich, heavy soil can sometimes cause the plant to focus on leaves rather than flowers.

Scarlet gilia: not flowering, causes and fixes

Likely causes

Lack of direct sun
Most likely

When to worry

Scarlet gilia is often a biennial, meaning it grows leaves the first year and flowers the second. If it is in its first year, it is normal for it not to bloom.

Stopping it coming back

Ensure the plant gets full sun throughout the growing season. Use a balanced fertilizer sparingly to support growth without sacrificing flowers.
